After watching your videos on capacitors last year I ordered a spare capacitor for my 22 year old air conditioner, just in case. Two weeks ago my capacitor failed on a hot humid day here in the south but I had the spare capacitor installed in about 10 minutes. The air conditioner was back up and running saving us from suffering through the heat and humidity which honestly is becoming more dangerous every year. Thank you for all your great advice and instruction, much appreciated. I'm a subscriber and a big fan of your videos.
Awesome! I love to hear that a spare capacitor was able to save the day. Way to act on that and order it last year. Thank you for sharing that, may you have a wonderful new week, stay cool!
Thanks to you I replaced my capacitor for $41 and got my A/C working before an HVAC company could even come out to look at it. 3 years ago I paid an HVAC company to replace a capacitor for $330. Thank you! Thank you! Thank you!!!!
Not defending HVAC companies, but capacitors are not the only thing that fails. Just had a home AC unit fail because the refrigerant level got too low (very small leak), and the low pressure sensor switch opened. System needs a recharge and possible leak detection procedure. I did the troubleshooting myself, but have hired a professional to do the work.
Jay, great to hear from you . If you make a “ temporary” substitution with a different value capacitor, it would be prudent to write the correct value on the unit in case that temporary replacement was forgotten about and became permanent. This way you know what’s SUPPOSED to be there. Stay well 👍👍👍
Good move. Also, it's good to know which sections of a dual capacitor go to what. Sometimes the notations on the terminals marked Herm and Fan are rusted over. Herm is the larger number e.g. the 45 of a 45+5, and goes to the compressor ("Herm" for hermetically sealed), and the other goes to the fan. If the markings are unreadable on your old capacitor, now you know. And the common terminal is typically labeled "C."
You saved me $30,000. My 5 ton had the fan wire on common for some reason and I replaced capacitor in 4 ton. Both working now. Every A/C person wanted to replace both systems.
For my Rheem unit, I have to get the same physical size because the "barrel" is placed through a hole in the casing. Smaller or bigger won't work but the OEM unit is readily available. Could you , one day, talk about installing a surge protector for the compressor? Love these videos.
Ah yes, in that case it would be better to have the same physical size. Although I've had times before (with Rheem units) where I simply laid the capacitor on it's side and strapped it down securely. That works too. And yes! I actually have a surge protector that's been sitting around which I got specifically to make a video with. I hope to make a video on that eventually.
Jay, very glad your still handing out sage advice on electronics. Having a spare capacitor on hand is a great to be prepared in case the one is the unit goes bad. Often the fix is to just replace the bad cap with a new one.
Some modern condenser units don't have a fan capacitor. Just worked on one that has a variable speed module before the motor, and no capacitor. It appears that the speed module spits out 3-phase power from a single-phase source, the motor seems to be 3-phase (no capacitor needed), and the capacitor is just for the compressor ("Herm" + C terminals on capacitor). Many condenser units have a schematic diagram inside the access panel that gets you to the capacitor and contactor (relay-solenoid) etc. which can be very helpful.
Just spent $170 for a guy to spend 10 minutes installing a $20 capacitor. Never again. Ordering a backup and know how to do it myself next time. Thanks for the video(s)!
$170 for diagnostic and labor of a qualified tech is not even that bad. Around here in Florida, most contractors charge $300 to $600 for the service and $20 part.

Capacitors are like everything else; there are trusted and less-trusted brands. Polypropylene caps are self-healing as they arc through the dielectric, so brands may say they have a high dielectric voltage tolerance but are the first to fail. Bojacks are known to manufacture a more high-end after-market cap. The larger can is due to a thicker dielectric, which lowers capacitance, thus requiring more foil length, making them more electrically robust. The physically smaller capacitor achieves the same capacitance by manufacturing with a thinner (therefore more prone to failure) dielectric, which raises the capacitance ( thinner dieletic=higher capacitance). The size indicates a construction difference in the dielectric thickness.
When my AC quit working I google the most common cause. Then removed the capacitor and took it to town ask my local hardware how to get a new one. He told me where to go. I went there and they tested my capacitor. It was bad so they sold me a new one. The first one lasted 14 years.
Sorry to hear that your AC stopped working but good to know that you were able to figure out what the problem was and get it fixed yourself. Stay cool sir!
Jay, thanks for this video! I was able to install an Amrad capacitor on our ac condenser. I would respectfully disagree with you about the brand of capacitor not mattering. I am OCD about research and it quickly became evident after reading thousands of reviews that cheap Chinese capacitors do not last much more than a year if that. Amrad capacitors seem to last at least five or more years and many are over twenty. I am all about going for quality instead of a cheap price. My 45-5 Amrad cost $36.94 with shipping from Dayton Industries in Palm Coast Florida. It was sent via usps in the manufacturer's box which was enclosed in a bubble wrap envelope. No damage like with many other sellers who slap the box in a cheap envelope that is unpadded. There may be good Chinese capacitors, but be sure to read the reviews. I'm lazy and don't care to replace my capacitor every year or less. Thanks for your great channel!

Thank you, I couldn't find the exact manual for my unit, found some very close and they all said it needed a 50/5. The bad capacitor on it was 40/5. Looked on the fan/compressor to confirm it was called for a 50/5. Thanks so much for that info.
You really know your stuff!! Thank you so much for making these video's . My air stop blowing cold & I did a lot of trouble shooting. I think I nailed it down to a bad capacitor. The unit is 6 years old & the capacitor has never been changed. Hopefully this will get us up and running again. Capacitor is on order should have it in a day or 2. I don't have a meter so I can't test the old one. I will let you know how everything goes! Have a wonderful Day & thanks Again!!
@@Phelper99I agree. If you have a Grainger nearby, they are a great choice. This past winter, the run capacitor went out on our HVAC blower motor at around 2AM. By 7:15 that morning I was walking out the door of the local Grainger with new capacitor in hand. Before 9AM, I had the capacitor replaced and the HVAC back in business. My wife was amazed and it cost about $6.
Hi Jay, another great video. I like to point out how careful you were while you loosened up the holding strap for the capacitor and not touching the wire terminals. 😁
Thank you! Haha better safe than sorry right? I don't remember for sure but I think I did turn the power off but didn't discharge the cap, that's why I was careful.
Last year the ac repair man came out to my house to fix my air conditioner. Come to find out, it was the fan side of the dual run capacitor. The herm side was still good. Instead of replacing the dual run capacitor, he piggy backed a small 5 ufd with the dual run capacitor. He said he ran out of dual run capacitors and all he had in his truck was the 5ufd capacitor. I got charged over $300 dollars just to replace a $10 dollar part! So now my air conditioner has two capacitors in it instead of one. Can you make a video on how it's wired? I've searched on CZcams for this and there isn't one for this scenario. Thanks for your videos. They have helped me understand how ac units work.
Sue them! They don't have the right to charge so much for repairs, we should shut down all HVAC companies, learn from this guy and do everything for free
I encourage everyone one to scrutinize the HVAC repair man! Watch what they are doing! The one that came out to my house would not let me use his ladder to get on my roof! I had to use my own ladder to get on the roof! I could tell by his demeanor, that he was not comfortable with me watching him do his work.
Thank you for sharing your story! This will be helpful for other homeowners to know. As for your question, these two videos should be able to help: How to Wire an Air Conditioner: czcams.com/video/KCanZEsLVEI/video.html How to Combine or Separate Capacitors: czcams.com/video/qLJOWU33TFo/video.html
@@WordofAdviceTV I kinda have an idea of how it's wired, but I'm not sure. I see the brown wire on one side and another wire that must be connected to common. Either through the common side of the contactor or the common side of the dual run capacitor. This totally bypasses the fan side of the dual run capacitor.
I like your videos and always waiting to see the most recent one. The less fortunate DIY person with a bit of intelligence learns from you and save some $$ in the process. Thanks
This is where a multi tap capacitor like a Turbo 200 is worth the money. The fluid in a turbo 200 is much thicker. The best part about an AmRad capacitor is they're American made you're putting food on an American workers table.
I hear ya but things made in China or wherever still produce some jobs and income for Americans. iPhones made in china so we lose out on Americans making money from assembling them but Apple still employs Americans and American stores that sell iPhones are American companies with American employees.
The larger number example 35 is for the compressor. The second smaller number is for the fan. If you change your fan motor to a different option you may need to change your capacitor too.
Great Cap info Jay ... I heard the guy that stole the batteries was later '' Discharged '' in that hi voltage case You have great neighbors ... Aloha my Friend ...
Hahaha I love it! The play on words is always fun! Aloha Eddy, always appreciate you joining in for the new videos!! May God bless you in this new week!
Your overall point that other specs than factory specs may often be substituted and will work fine. Shape factors may be different (as long as the parts are secured to endure vibration of the condenser housing). Actually, you may have a point that "the voltage rating is not important" for most HVAC units in the USA and Europe, ie 360v/440v but that is not true for capacitors in general and may be very important. Rule of thumb...you can use a capacitor with a differing but close capacitance rating and you can use a capacitor with higher voltage rating but NOT LOWER voltage rating (lower voltage rating may otherwise burn out). Also, capacitors have polarity (+/-) that must be respected when installing or replacing. Overall good, helpful video, thanks.
I think it's a good idea to buy a capacitor and have it as a spare. They tend to fail on the hottest day of the year and there's no average life expectancy on them so it's hard to predict when they will fail. I've seen some last over 30 years and others that didn't even make it to a year.
Nuance....an original capacitor rated ONLY at 440V should NOT be replaced with a capacitor rated ONLY at 370 V...right?..... we can go up in voltage rating, but not down. This becomes almost a non issue because (as you say)...most replacement units show both voltages. Cheers.
In short, the start capacitor helps the unit start and then it is taken out of the circuit whereas the run capacitor is in use the whole time while the unit is running.
If you do not know this answer, you have no business working on an HVAC AC or heat pump condenser system. These are high-voltage 220/240 volt systems and the start and run windings are very important to the function. Replacing these parts are not for DIYers. This isn't like replacing your windshield wipers, this can be dangerous equipment.
I recently replaced the AC and furnace capacitors on my 9 year old 5 ton Goodman system. The original 20 mfd furnace capacitor was down to 17.8 mfd and the 70/5 mfd AC capacitor was still 69.8/4.9 mfd I kept it for spare. To my surprise the condenser fan was not connected to the capacitor…just the red wire connected to C and the yellow wire to Herm. I chose to pay a bit more and bought the U.S. made capacitors…although, I don’t know if it really matters. Also, do capacitors have a shelf life? Do they go bad even if they aren’t used? As per your advice, I also ordered a hard start kit and got it today but after watching some more CZcams videos on that topic, I decided not to install it as long as my AC keeps starting so smoothly. No lights flickering either.
What about the +_% number next to the úf numbers? Does the 5 or 6 matter? Mine is a 45+5 uf - 5% and I'm having a very hard time finding that same one. I keep finding them with 6%
Brand does matter, buy American made and buy the exact size required for your system. The wrong capacitor in the system might have replaced by someone else before you and or the fan requires a different Microfarad than from the factory. Only a trained technician should do this type of work and will void your warranty, if it has one. Most systems have 10-12 year parts warranty. Do not guess on the size of the capacitor. That is like guessing which spark plug your vehicle takes or which oil. It is not OK to use a different size capacitor. It will shorten the life of the fan or the compressor and those can be very expensive to replace and VOID your warranty.
@@hahaha9133 Oh, that is too bad you don't buy the best product and you sell junk to your customers. AMERICAN MADE ONLY!! Anything else is junk. I am actually care about my customers and my country!!
Cool. Thank you. Question: What about the + or - 5 / 6. Does that matter? For example, I am replacing a 45/5 +/- 5 with a 45/5 +/- 6. Is this OK? I understand those numbers and what they do.Which is testing the capacitor good or bad. So does replacing +/- 5 with a +/-6 matter?
Thank you for the video!! My current capacitor says 45/4uF, but at the market sells only 45/5uF . Can i use this or should find 45/4 ? Please let me know!
It would be best to find the 45/4 but if you can't find it anywhere, then a 45/5 will have to do. It may shorten the lifespan of the fan motor a bit though.
The capacitor info may be on the compressor or on the fan motor but most condenser nameplates (where the unit model and serial are) don't have capacitor info on them.
THANK YOU SO MUCH. THAN I CAN INSTALL TENPORARY CAPACITOR I F I DONT HAVE TH RIGHT MICROFERS SO IF U NEED 45 fs I COULD GO 40 or 50 AT LIST FOR CUPLE DAYS AGAI THANK YOU SO MUCH
You're very welcome! Yes, it's okay to use a different size for a short time. 👍 I have seen some technicians put in a 60MFD instead of a 30MFD and it worked fine for 3 weeks until I got back there. 😅
I was needing to replace mine and the old one has only some of the label remaining and says 10/50MFD. I ordered one that said 10/50 but now that I have received it, it says 50+10 MFD. Is this the right one? I can't seem to find 10+50MFD anywhere
Yes, it should be the right one. The larger number will always be for the compressor and the smaller number is for the fan. It does not matter in which order the numbers are.
Hi Jay, Good to see another video from you. I have a16 year old, Bryant, 3 ton, R-22 unit on which I replaced the contactor and that cured on/off every few seconds until it would finally run problem I was having with it. Prior to that trying to fix the problem, I installed a Supco hard start kit. Should I take the hard start kit off now that the real problem (the contactor) has been fixed? Thanks
Hey Jay, I just found your channel and really love the content. I'm experiencing a very odd situation with my condensing unit and was wondering if you have any suggestions. A couple of day ago I noticed the fan was turning on and off. Like it runs for 3 to 5 seconds the off for maybe 45 to 60 seconds and repeats that forever. The compressor never shut off. It will run 24-7 while the fan does its 5-60 seconds deal. I changed the run capacitor (thanks to your video) but that wasn't the problem. Any suggestions?
Dude you're the Man! I notice all the run capacitor I see the larger number is stated first for the MFD. For instance 35/5 uf. For some reason my existing one that I need to replace, the smaller number is stated first 5/35 uf. Would it be the same? I know the larger number should be for compressor and small number should be for fan.
Great videos and education as usual. I was curious to know though would you put a hard start kit On a new condensing unit? A hard start kit came as part of the deal with the new HVAC system, but the technician said he wouldn’t put it on, if it was his system, because the capacitor that was there was so new. He suggested waiting a few years. Also, if you bought a spare capacitor, how long would it be good for? Several years, or do they age over time.? Your thoughts? This system is only one year old. Your thoughts.
Jay - I'm replacing my mechanical contactor with an Emerson SureSwitch. I traced all the wires so I know what goes where. However, the 2 wires from the crankcase heater appear not to be connected correctly, as they are connected to L2 and T2. This doesn't make sense to me and I don't know how this can possibly work. Interestingly, this 34 year old condenser unit has never been repaired, except I replaced the compressor cap last summer. Any idea why these wires are connected like that? Thanks for an Word of Advice you might have. ;-) Jeff
Very helpful video. I'm replacing both of my capacitors for my ac unit. They are both Sprague brand which no longer exist. One is 4 UF/370 VAC 60HZ. The other is 25 UF/370 VAC 60HZ. What capacitor can I use for replacement? I am coming across many with plus minus 6%. I don't know if those with plus and minus are compatible
I know you said none of the other numbers matter, but the a/c guy that came out said I also needed to match the ±6% beside the 45/7.5µF as well. So, do I need to match that number also? Or can I just match the 45/7.5µF? Thank you!
If you find one that matches all the numbers, great! 👌 But if you can't find the exact one, as long as the uf rating matches, it'll work fine. (In fact even a wrong mfd rating would work but I don't want to encourage that so I usually don't mention it)
hey Jay really like your videos and your explanation of what you are doing to test and replace. i looked for your video of testing capacitors but couldn't find it. it was mentioned in video - "FURNACE BLOWER NOT WORKING AND HOW TO CHECK IT". PLEASE DIRECT ME THROUGH THE MAZE OF CZcams VIDEOS TO FIND IT. THANKS A LOT.

@@Alexander42099 doesn't matter, thats just the allowable range above or below the rating on the capacitor to determine with a meter to see if it's still in range.

You really know your stuff!! Thank you so much for making these video's . My air stop blowing cold & I did a lot of trouble shooting. I think I nailed it down to a bad capacitor. The unit is 6 years old & the capacitor has never been changed. Hopefully this will get us up and running again. Capacitor is on order should have it in a day or 2. I don't have a meter so I can't test the old one. I will let you know how everything goes! Have a wonderful Day & thanks Again!!
How did it go? I'm about to order one from Amazon today and connect it tomorrow.
Thank you for this. Now where can I buy a capacitor for my ac unit?
Amazon
Grainger
@@Phelper99I agree. If you have a Grainger nearby, they are a great choice. This past winter, the run capacitor went out on our HVAC blower motor at around 2AM. By 7:15 that morning I was walking out the door of the local Grainger with new capacitor in hand. Before 9AM, I had the capacitor replaced and the HVAC back in business. My wife was amazed and it cost about $6.
@hoboken5224 You're welcome! I added a pinned comment under this video with a bunch of Amazon links to capacitors. 👍
Hi Jay, another great video. I like to point out how careful you were while you loosened up the holding strap for the capacitor and not touching the wire terminals. 😁
Thank you! Haha better safe than sorry right? I don't remember for sure but I think I did turn the power off but didn't discharge the cap, that's why I was careful.
@@WordofAdviceTV Awesome work, and a great joke. Still laughing my friend. 😂 😂
Can you make a video about soft starts and hard starts and their purpose?
Useful explanation
Thanks so much.
Very helpful video, Thanks Jay!
Last year the ac repair man came out to my house to fix my air conditioner. Come to find out, it was the fan side of the dual run capacitor. The herm side was still good. Instead of replacing the dual run capacitor, he piggy backed a small 5 ufd with the dual run capacitor. He said he ran out of dual run capacitors and all he had in his truck was the 5ufd capacitor. I got charged over $300 dollars just to replace a $10 dollar part! So now my air conditioner has two capacitors in it instead of one. Can you make a video on how it's wired? I've searched on CZcams for this and there isn't one for this scenario. Thanks for your videos. They have helped me understand how ac units work.
Sue them! They don't have the right to charge so much for repairs, we should shut down all HVAC companies, learn from this guy and do everything for free
czcams.com/video/GhBTVn5CHBE/video.html&feature=share8
I encourage everyone one to scrutinize the HVAC repair man! Watch what they are doing! The one that came out to my house would not let me use his ladder to get on my roof! I had to use my own ladder to get on the roof! I could tell by his demeanor, that he was not comfortable with me watching him do his work.
Thank you for sharing your story! This will be helpful for other homeowners to know. As for your question, these two videos should be able to help:

@@WordofAdviceTV
I kinda have an idea of how it's wired, but I'm not sure. I see the brown wire on one side and another wire that must be connected to common. Either through the common side of the contactor or the common side of the dual run capacitor. This totally bypasses the fan side of the dual run capacitor.
Excellent videos!
Thank you! 🙂
I like your videos and always waiting to see the most recent one.
The less fortunate DIY person with a bit of intelligence learns from you and save some $$ in the process.

Great advice and knowledge to have!
This is where a multi tap capacitor like a Turbo 200 is worth the money. The fluid in a turbo 200 is much thicker. The best part about an AmRad capacitor is they're American made you're putting food on an American workers table.
I hear ya but things made in China or wherever still produce some jobs and income for Americans. iPhones made in china so we lose out on Americans making money from assembling them but Apple still employs Americans and American stores that sell iPhones are American companies with American employees.
Can you make a video that can show homeowners how to check how much Freon they have in their using gauges that they can buy from Amazon.
This video is similar to what you are asking for but keep in mind that there are different refrigerants too. czcams.com/video/dExFtP-nXTw/video.html
Thanks, I took a picture of my capacitor and ordered one from Amazon today for $18.00.. All I need is a screwdriver to replace it should it go bad.
When replacing, does it matter which terminal the connector is put on...like which of the 4 on the common or which of the 3 on herm?
The prongs in each section are connected, so it does not matter which terminal you put it on. 👍
I was told the best thing to do is take a picture before you remove the old one and then use that as a guide for the new one.
The larger number example 35 is for the compressor. The second smaller number is for the fan. If you change your fan motor to a different option you may need to change your capacitor too.
Thanks, great info!😎
Glad you found it useful! 👍
What is a good brand Capacitor? Amazon goes from $15 to $35 . I need a 45/ 5 . Are the Cheap ones just as good as the more expensive?
Usually yes. The expensive ones fail just as much as the cheap ones. Buy a USA built one if possible, that might increase the longevity.
Great Cap info Jay ... I heard the guy that stole the batteries was later '' Discharged '' in that hi voltage case You have great neighbors ... Aloha my Friend ...
Hahaha I love it! The play on words is always fun! Aloha Eddy, always appreciate you joining in for the new videos!! May God bless you in this new week!
You are great. Thanks
Thank you! 🙂
Your overall point that other specs than factory specs may often be substituted and will work fine. Shape factors may be different (as long as the parts are secured to endure vibration of the condenser housing). Actually, you may have a point that "the voltage rating is not important" for most HVAC units in the USA and Europe, ie 360v/440v but that is not true for capacitors in general and may be very important. Rule of thumb...you can use a capacitor with a differing but close capacitance rating and you can use a capacitor with higher voltage rating but NOT LOWER voltage rating (lower voltage rating may otherwise burn out). Also, capacitors have polarity (+/-) that must be respected when installing or replacing. Overall good, helpful video, thanks.
Actually, since all A/C systems run on alternating currant, the capacitors do NOT have polarity.
Amazing content. You are awesome
how often does homeowners needs to change their capacitor? And how long does capacitor last?
I think it's a good idea to buy a capacitor and have it as a spare. They tend to fail on the hottest day of the year and there's no average life expectancy on them so it's hard to predict when they will fail. I've seen some last over 30 years and others that didn't even make it to a year.
Thank you for the much needed information. Can you please do a similar video with a contactor?
You're welcome! I answer most contactor questions in this video: czcams.com/video/qHZc9wWAF4c/video.html
Nuance....an original capacitor rated ONLY at 440V should NOT be replaced with a capacitor rated ONLY at 370 V...right?..... we can go up in voltage rating, but not down. This becomes almost a non issue because (as you say)...most replacement units show both voltages. Cheers.
Thank you Jay great video.
You're welcome, glad you liked the video!
Thank you.
You're welcome! 🙂
Great info

What is the difference between the start capacitor and the run capacitor?
In short, the start capacitor helps the unit start and then it is taken out of the circuit whereas the run capacitor is in use the whole time while the unit is running.
If you do not know this answer, you have no business working on an HVAC AC or heat pump condenser system. These are high-voltage 220/240 volt systems and the start and run windings are very important to the function. Replacing these parts are not for DIYers. This isn't like replacing your windshield wipers, this can be dangerous equipment.
Helpful information, thank you for sharing bro !!
I recently replaced the AC and furnace capacitors on my 9 year old 5 ton Goodman system. The original 20 mfd furnace capacitor was down to 17.8 mfd and the 70/5 mfd AC capacitor was still 69.8/4.9 mfd I kept it for spare. To my surprise the condenser fan was not connected to the capacitor…just the red wire connected to C and the yellow wire to Herm. I chose to pay a bit more and bought the U.S. made capacitors…although, I don’t know if it really matters. Also, do capacitors have a shelf life? Do they go bad even if they aren’t used?
As per your advice, I also ordered a hard start kit and got it today but after watching some more CZcams videos on that topic, I decided not to install it as long as my AC keeps starting so smoothly. No lights flickering either.
Don't worry about shelf life. Unless it is sitting in water.
Another tip: Buy an extra 1 or 2 capacitors. They are super cheap enough and you can leave them somewhere when needed.
Amen! Very good tip. 👍
I keep a set of capacitors and a contractor as well as furnace parts on hand at all times. It’s just smart, they don’t go bad.👍

What about the +_% number next to the úf numbers? Does the 5 or 6 matter? Mine is a 45+5 uf - 5% and I'm having a very hard time finding that same one. I keep finding them with 6%
The % doesn't really matter. 6% will work good 👍
Thanks, it helped
From your experience, what brand is the most reliable?
Bojack and Genteq is good, but the best of the bunch is AmRad
@@EliteGeeksand Amrad is made in USA with a good warranty
How do I know whether I need a start run duo capacitor or start or run capacitor for my AC? Thanks!
Brand does matter, buy American made and buy the exact size required for your system. The wrong capacitor in the system might have replaced by someone else before you and or the fan requires a different Microfarad than from the factory. Only a trained technician should do this type of work and will void your warranty, if it has one. Most systems have 10-12 year parts warranty. Do not guess on the size of the capacitor. That is like guessing which spark plug your vehicle takes or which oil. It is not OK to use a different size capacitor. It will shorten the life of the fan or the compressor and those can be very expensive to replace and VOID your warranty.
American made blah blah blah
@@hahaha9133 Oh, that is too bad you don't buy the best product and you sell junk to your customers. AMERICAN MADE ONLY!! Anything else is junk. I am actually care about my customers and my country!!
Excellent bro....
Good advise
Cool. Thank you. Question: What about the + or - 5 / 6. Does that matter? For example, I am replacing a 45/5 +/- 5 with a 45/5 +/- 6. Is this OK? I understand those numbers and what they do.Which is testing the capacitor good or bad. So does replacing +/- 5 with a +/-6 matter?
Either 5 or 6% will both work the same. You can use either one. 👍
Thank you for the video!!
My current capacitor says 45/4uF, but at the market sells only 45/5uF . Can i use this or should find 45/4 ? Please let me know!
It would be best to find the 45/4 but if you can't find it anywhere, then a 45/5 will have to do. It may shorten the lifespan of the fan motor a bit though.
Isn^t the correct info for the capacitor written on the condensers rating info
The capacitor info may be on the compressor or on the fan motor but most condenser nameplates (where the unit model and serial are) don't have capacitor info on them.
Gracias Maestro!!!!
THANK YOU SO MUCH. THAN I CAN INSTALL TENPORARY CAPACITOR I F I DONT HAVE TH RIGHT MICROFERS SO IF U NEED 45 fs I COULD GO 40 or 50 AT LIST FOR CUPLE DAYS AGAI THANK YOU SO MUCH
You're very welcome! Yes, it's okay to use a different size for a short time. 👍 I have seen some technicians put in a 60MFD instead of a 30MFD and it worked fine for 3 weeks until I got back there. 😅
0utstanding!👌
I appreciate that! 🙂
Really great information!!
Thank you. Glad it was helpful!
the spider got fried
I was needing to replace mine and the old one has only some of the label remaining and says 10/50MFD. I ordered one that said 10/50 but now that I have received it, it says 50+10 MFD. Is this the right one? I can't seem to find 10+50MFD anywhere
Yes, it should be the right one. The larger number will always be for the compressor and the smaller number is for the fan. It does not matter in which order the numbers are.
Hi Jay, Good to see another video from you. I have a16 year old, Bryant, 3 ton, R-22 unit on which I replaced the contactor and that cured on/off every few seconds until it would finally run problem I was having with it. Prior to that trying to fix the problem, I installed a Supco hard start kit. Should I take the hard start kit off now that the real problem (the contactor) has been fixed? Thanks
Does this word the same for an air compressor?
Thanks for the help!
Hey Jay, does it Matters if the unit is a heat pump or none heat pump.
I always buy made in USA !!!! They are much better in my opinion
Mine has a rating listed 5/45 uF. When searching in Amazon I'm finding 45/5 . Will it be the same thing. Is the rating listed backwards?
Same thing. The bigger reading will always be for the compressor/herm
@@WordofAdviceTV Thank You so much
Hey Jay,
I just found your channel and really love the content.
I'm experiencing a very odd situation with my condensing unit and was wondering if you have any suggestions.
A couple of day ago I noticed the fan was turning on and off.
Like it runs for 3 to 5 seconds the off for maybe 45 to 60 seconds and repeats that forever.
The compressor never shut off. It will run 24-7 while the fan does its 5-60 seconds deal.
I changed the run capacitor (thanks to your video) but that wasn't the problem.
Any suggestions?
Dude you're the Man! I notice all the run capacitor I see the larger number is stated first for the MFD. For instance 35/5 uf. For some reason my existing one that I need to replace, the smaller number is stated first 5/35 uf. Would it be the same? I know the larger number should be for compressor and small number should be for fan.
Do you have to put the dead spider back on top for it to work?
The dead spider would be an added bonus but not mandatory. 👍
Great videos and education as usual. I was curious to know though would you put a hard start kit On a new condensing unit? A hard start kit came as part of the deal with the new HVAC system, but the technician said he wouldn’t put it on, if it was his system, because the capacitor that was there was so new. He suggested waiting a few years. Also, if you bought a spare capacitor, how long would it be good for? Several years, or do they age over time.? Your thoughts? This system is only one year old. Your thoughts.
We replaced our capacitor last year, but the unit had a freon leak.
Sorry to hear that! A freon leak unfortunately is not as easy to deal with as a capacitor..
Jay - I'm replacing my mechanical contactor with an Emerson SureSwitch. I traced all the wires so I know what goes where. However, the 2 wires from the crankcase heater appear not to be connected correctly, as they are connected to L2 and T2. This doesn't make sense to me and I don't know how this can possibly work. Interestingly, this 34 year old condenser unit has never been repaired, except I replaced the compressor cap last summer. Any idea why these wires are connected like that? Thanks for an Word of Advice you might have. ;-)
Jeff
Aack! I'm a dummy. I see how it works now. Brain fart.
Glad to hear you figured it out! Stay cool good sir!
FROM CHICAGO THANK YOU SO MUCH FOR YOUR TIME SHOWING YOUR VIDEOS.WHAT DO YOU THINK ABOUT BETWEN HEATPUMP and FURNACE/AC CONDENSER
I'LL BE ANXIOUS FOR YOUR ANSWER AND AGAIN THANK YOU SO MUCH FROM CHICAGO
what is the best brand for AC capacitor
Supposedly one of the best ones is AMRAD.
Very helpful video. I'm replacing both of my capacitors for my ac unit. They are both Sprague brand which no longer exist. One is 4 UF/370 VAC 60HZ. The other is 25 UF/370 VAC 60HZ. What capacitor can I use for replacement? I am coming across many with plus minus 6%. I don't know if those with plus and minus are compatible
I know you said none of the other numbers matter, but the a/c guy that came out said I also needed to match the ±6% beside the 45/7.5µF as well. So, do I need to match that number also? Or can I just match the 45/7.5µF? Thank you!
If you find one that matches all the numbers, great! 👌 But if you can't find the exact one, as long as the uf rating matches, it'll work fine. (In fact even a wrong mfd rating would work but I don't want to encourage that so I usually don't mention it)
Nice
Thanks! 🙂
I just got charged $358 for a capacitor + $122 trip charge. Im definitely ordering spares.
Is there a difference if it says 40/5 or 40+5?
They are the same thing. Kind of like we're = we are.
@@WordofAdviceTV got it, thanks man!!
hey Jay really like your videos and your explanation of what you are doing to test and replace. i looked for your video of testing capacitors but couldn't find it. it was mentioned in video - "FURNACE BLOWER NOT WORKING AND HOW TO CHECK IT". PLEASE DIRECT ME THROUGH THE MAZE OF CZcams VIDEOS TO FIND IT. THANKS A LOT.
Glad you found the videos helpful! So I am not sure which video you wanted me to give you the link for but just in case here's both of them:

i have a question maybe you can help me out. My ac unit has a 35+10 inside it and the spec at default come with a 45+5. is this going to be an issue?
Yes, long term that will damage the compressor and fan motor. I would replace it with the proper size.
Very niece sir ji ❤❤❤💖😘🇮🇳
So what if on my old capacitor it states 35 + 5uf? Obviously with a backwards u, but all I could find was on ace hardware but it was 35+5mfd?
That's the same thing. MFD and uF is interchangeable.
Capacitor 45+5.0uF +/-6% 440VAC/B
How can I buy this capacitor because mine is too old? What number should capacitor I buy?
This one would work: amzn.to/3YCsftD
Does the +/-% matter? The current unit is 5%, most available online are 6%.
6% will work the same as 5%. Either one is fine.
lol i just commented on another vid about the capacitor. does the percentage matter?
6 or 5 ? my motor doesnt says which %
@@Alexander42099 doesn't matter, thats just the allowable range above or below the rating on the capacitor to determine with a meter to see if it's still in range.
@@Alexander42099 Only way to tell if it's having an adverse effect on your system is to use a clamp meter to check FLA of the fan motor or compressor.
