- How to replace a contactor on an AC condenser unit. In this video I show and explain how to change out an air conditioner contactor. I replace a single pole contactor with a double pole contactor. I talk about all the safety precautions, what the amp rating should be, whether you should get a one pole or a two pole contactor, which side the power wires need to go on, and other tips involved with replacing a contactor.

Thanks for sharing your knowledge
I decided to replace both my capacitor and 2 pole contactor as maintenance items after watching Jay's video. Upon inspecting the old contactor, I found all 4 contact points to be heavily pitted. It was on the road to failure, for sure. The contactor cost me around $15 on Amazon. The a/c repair folks charge in excess of $300. Cant say enough good things about Jay's videos. Thanks so much
Thank you so much!! I'm 61 year old female and was replacing a contactor to an older Trane AC. The connectors were like the ones in this video, some were female connectors and some were rounded connectors. You saved me time of not having to change the round connector ends. I was going to go buy female connectors and switch them out.
Original problem was outside fan was coming on but not compressor. I had AC repair come out yesterday and said I had a bad capacitor and contactor. He wanted to charge me $275 to replace a $9 capacitor and $309 to replace $26 contactor. I paid him the $75 diagnostic fee and told him I would do it myself and I did thanks to your videos.
Hopefully you didn’t get hurt or ruin your machine. Seen so many homeowner destroy their compressor or harm themselves. We are trained professionals for a reason.
@@marcusfitzgerald59your inflated fees are driving the diy community to watch CZcams videos and get up off the couch to save $$$$. All this job was only part swapping, standard A/C maintenance. I’ve had A/C techs come to my house and misdiagnose a problem to my A/C.
Your videos are helping the diy community to grow. This is just part swapping and standard maintenance to an A/C. I’ve had A/C techs come to my house and miss diagnose a problem. The tech told me the problem was an $850 compressor when the real problem was a $150 expansion valve problem. A/C techs inflated fees are helping our diy community to finally get up off the couch.
BRAVO!...finally someone who knows how to present ac problem solving in an understandable way. Thank you.
Your videos are simple, straightforward easy to understand. Can’t thank you enough.
I'm kinda technical, but working on my AC is new to me. So thanks, you helped a lot!
Word of Advice HVAC is the hands down best quality, best examples, best host -- for this subject matter.
We all appreciate your thorough, helpful troubleshooting videos.
I agree. I like the way he explains everything and shows you how to do things.
Great Video. I followed the instructions and i was able to replace the contactor of my HVAC unit with no issue. Happy to find this video.
Jay, you are the man! Your excellent tutorials told me everything I needed to know and the courage to replace my 15 year old capacitor and contactor that a service repairman said, during a routine PM, were close to failure. As in your video, my screw over connectors had to be crimped, but unlike yours, this was no easy task. I discovered that cutting open the ring with wire cutters and then crimping it, worked like a charm. Just a little idea you might want to pass along.
Thank you so much for your video. I used your video to replace my AC condenser contactor. It saved me couple hundred dollars to call for service. Great job on the video.
Man, you are a Professor of all things instructional concerning home cooling and heating...thank you for sharing the elite wisdom God has given you to help so many of us out here in cyber land.y issue was that at times, my condenser unit would keep running after the AC would cycle off in the house. I would go outside and see the line from the unit to the house frozen... problem was the contactor sticking (which a slap on the side would loosen)... but now is fixed... with the new contactor for $23.86 and guidence from you!😊
Once again you saved me time and money. At first, contactor was full of dead bugs. After blowing and cleaning, it still did not work. Decided to replace it - easier than I thought thanks to your video. And voila! Thanks.
Local company wanted $783 to replace contactor. Just the contactor. Included in that fee they had a $69 fee to drive to the house, 4 miles from their door, and a $100 diagnostic fee. Crazy.
This video just saved my weekend (and a 2 week wait), thank you so much for your clear, easy to follow instructions on how to do a thing that really intimidates most people.
We now have someone who knows what they're talking about. Great job Jay❤.
Thank you sooooo much. I watched many of your videos to diagnose my AC system. It took me some time to figure the problem out but with your instructions and knowledge you saved me hundreds, if not thousands of dollars. I only paid about $15 for parts and a little time. THANK YOU!!!!!!
Perfect perfect perfect explaination you are #1 in CZcams ! Good job explain every thing from 0 to 💯
10/10
Thank you! :) It's an honor to get such high marks! I appreciate you taking the time to leave a comment.
@@WordofAdviceTV what cause the negative value subcooling?
I have 410a and the liquid line temp was over 140 f and the red gauge read 102f
The system was low in 410a and I put 3lbs that dropped the temp on the low side pipe from 210f to 140 but like I said it's still high and result in negative subcooling value!
The low side is reading 40f on gauge and the temp prop on the low side read 68f
So the high side pressure is about 345psi and the low side is about 145psi based on the guages reading
The outside temp was 74f afternoon
The system is roof mount train
Thanks
Every tubers needs to learn from you in making instruction video. Your explain and teaching are awesome, clear on every point. Thank you. Now im confident to go back outside to replace my contact and capacitor.
Thanks so much for making these videos. Most complete, easiest to understand A/C help videos out there.
FANTASTIC! YOu are a natural at explaining things! Thanks for making things easy and for explaining the every you’re doing! You’re a great teacher! You get an A+ for the day! Thanks again!
Your friend,
Barry
Another excellent video, super clear and good explanations. The safety tips are critical, especially since many are DIYERS and it never hurts to hear it again. 🙏🏼
Very thorough explanation and clear video. The best I have seen-Thank you!
I have a two 20 year old AC units and have started replacing the capacitors and contactors.
The slide on connectors for the capacitors were very dull looking. I grabbed them with a needle nose and polished them up with a slim brass brush. I would recommend this easy step to insure the best connection. Also like your idea to crimp them down a little if loose.
I only wants to say thank you very much for the time that's you used to teach us, I'm not a technician or anything but with his help o did the job, he explained very well what's to do with a contactor that isn't labeled .. I did what he said and abracadrabrapatasdecabra... worked...
Thank you bro..
Best Hvac teacher 👨🏫 ever
Thanks 🙏🏼 very much appreciated
This guy is just full of good game, thanks for sharing man. 💯
Insane! You explain things clearly. Best video I have seen.
You are just the best, very clear on everything...
I just started to learning about HVAC and I found your channel. You speak briefly about certain subjects that's a beneficial for us. Thanks for sharing your thoughts, keep up good work.
Glad to hear you found the videos useful! Thank you for watching and commenting!
This was an excellent video, thank you for your high quality and attention to detail. One extra tip: Test your meter at the disconnect before trusting it reads 0 everywhere.
Great instructional video! Been in a heatwave here in the northeast and Wed evening the AC unit was just just blowing hot air from the inside air handler. Went outside and the manganic connector was fried (27yrs old) Replaced that and figured I'd do the coil at the same time as that even though it was still good (at the 27 years old also, it just mad sense to do both.) Also take lots of photos for the wiring for reference as each unit is different and even jot down a few notes. Made the installs trouble-free. Both parts from Grainer came to $85.
One of the best vids on this topic.......great job !!!!
Thank you for the great videos, I've watched several, our heat pump has been running on emergency heat for a couple of weeks (propane) I discovered the single pole contactor had burned up one of the contacts, it's 10 years old, I ordered another on internet $12, should have it in a couple of days 👍
Thank you for this. As a rookie DIYer, i was able to tackle my contactor replacement with no problems and for a fraction of the cost.
Lucky guy. I paid $330 to an AC guy on Labor Day for a run capacitor. Then I see this man's videos. $300 in the AC man's pocket. Come on. How about $130? Kind of a shame the ripoff games in HVAC.
Thanks so much, all your instructions are clear and easy to follow, great job!
Thank you so much. I'm replacing a very old contactor and had questions about the coil wires and the old style connectors. I did not think about flattening the connector to get it under that screw terminal.
Another great video, You do a great job of explaining the repair you do in each and every video, great job 👍
Thank you! :) It's nice to hear that!
Thank you for the instructions. I watched very much all of the troubleshooting AC videos you have, and I able to fixed my AC issue. It was contactor related. The reading was well below 12ohms.
Sir, thanks for your knowledge and explicit instruction, which gave me the courage to replace a bad contactor.
Great explanation of what to do and why. You anticipated my questions on contactor compatibility, 1 vs 2 pole, and how to adapt leads for contactor.
You are awesome brother! I wish all HVAC techs were as knowledgable and thorough as you. Most techs are rude and selfish. In my experience, most HVAC techs don't know how to teach you or have the patience to teach you. You should really consider being an instructor brother. You have the temperament to do it.
Thanks so much Jay for the awesome video.
19 and ty for all your great videos ! You are a master of all trades !
you are an awesome creator. The content is so clear and also sharing your previous videos where you have covered a topic is super helpful. Please keep doing what you are doing, its helping a lot of people.
You are the MAN!!! Thank you so much brudda!!!! Two minutes into the vid you answered my question! Can you replace a 30 with a 40? YUUP!! I am going to be watching some more of your very excellent vids!!! THANK YOU!
This video and a few of the others you had helped me solve my AC issue. Started off thinking it was the thermostat, after blowing several fuses, slowly rulled out each link in the chain. Turns out my contactor when testing only gave 1.2 ohms when testing it. I just got the part today and installed it! AC is working as it should!
Just got into facilities maintenance been at it for about a year. Came across a pretty burnt contactor. Changing it tomorrow. Great video thanks chief
You always explains my problems so easy thank you.
Best channel for hvac!!
Buy a spare one of these and keep them on hand. $15 part and easily replaced. Same goes for capacitor. I had my AC go out late in the afternoon and could not buy a contactor. Had to hard wire where contactor goes and use the main breaker by the condenser to use the AC. Worked great for that night. Make sure the thermostat is on so the fan runs while compressor is on. Next morning got the part and changed it out. Great video. Thanks
Thanks for a great video went to my local ac place grab a 15.00 part fixed you saved me a ton of money thanks thanks
Thanks for sharing your knowledge on AC units👍🏼👍🏼👍🏼👍🏼
Great video! 🤙🏽🤙🏽

Thanks Mr. Classic! :) Glad you liked the brick joke! I think I will be using the "no, sun" joke next.
Word of Advice TV,
I’m looking to sell my Delorean,
It’s in great shape, low mileage.
Only driven from time to time....
Haha nice one! :) I've seen that one on Reddit before. I liked this reply: Good shape? Are you aware that there are easily available recorded videos of the stunts you've pulled with this car? If this car's in good shape then I'm my own father!
Man another great video. Thanks
Bro you are the beast you are the best program that you have thank you for everything .
I love the way you explain best ever thank you it’s help a lot 😊
Excellent channel! Very helpful information. Thanks for the recommendation of discharging the capacitor! Good safety step.
Buen video gracias por su gran trabajo!
I replaced our AC contactor about year and a half ago thanks for your help and for your videos.
Glad to hear the videos helped! Thank you for watching and commenting!
I just watched your video on contactors single or double pole and replacing a single with a double pole contactor and checking if a CCH is there, I think the tech should check the schematic before changing 2 reasons at this point CCH can be connected to L1 and L2 with a hi temp thermostat on discharge line to stop heater and important the K2 defrost relay BK wire placement on the contactor....
Thanks I enjoy your teaching and I really want to learn more about
Out standing video thanks J
THANK YOU SO MUCH! I have to DIM (Do It Myself) as I am a single, private school teacher. I just replaced my contactor today and before I POWER ON, I wanted to be sure I got it right, so I watched one more video - this one. I also sent pics to my Uncle - an electrician to have him inspect it. I had an 8 wire, that I had to clip and strip the 1998 clamps off and insert. Thanks for the old/new pic as yes, the smaller coil wires are on opposite sides and you helped me look on the bottom to understand how they are attached to the coil. It is June 28, 2020 - in TEXAS - thank God it has been overcast and cool these past several days since I ordered my contactor 1-pole 30amp 24v. So I will now power on as I place my trust in God the ultimate technician who has helped me learn. My older contactor lasted 22 years!!!! Wow! It was sticking last fall prior to winter, so again, sticking in beginning of June, needed to replace it. Thank you for your educational video - you are easy to learn from. May God Bless you richly!
GREAT JOB
Thanks so much for your video!
Excellent info!! Thank you so much :)
You are the best.
Thank you
Thanks so much for the helpful videos! My hvac won't cool, the fan outside isn't spinning, and after turning everything on using the thermostat, I can't turn the system back off again (fan on auto, system on off). Last year I had a similar problem with the unit not cooling and getting stuck on. Repair technician said it was the contactor and replaced it (had a power surge that took it out). This year I'm thinking that it has to be something different since I keep hearing that it's not usually the contactor. Thanks to your videos, I've tested both the capacitor (35+5 read as 34.6+5) and I tested the fan motor (got 55, 23, and 79 between the wires so it seems the motor is good too). I decided to finally look at the contactor before checking the compressor itself. After removing the contactor cover, I noticed the metal contact looks all scratched and pitted and there are black scorch marks. The plunger isn't stuck in, I can press it easily enough. But I'm wondering if it is bad.
I plan on replacing it due to the damage but I'm trying to find out what is the most important features to keep in mind when buying a new one. I have a single pole and I'm trying to match up all the numbers exactly when searching Amazon and it's kind of hard to find an exact match. Wondering how important the FLA/LRA/RES are to get exactly matched right. Anyway, thanks so much for these helpful videos! So grateful for such educational information!
Excellent description!!

Thank you!
Like always an excellent video and informative n have a good day
Getting ready to attempt both capacitor and contactor replacement. Wish me luck
Dan here, I watch a lot of your videos and think the are great. My comment is on your video "how to replace a contactor". You stated there was only one reason to not to replace a single pole with a double pole. I was watching other videos (not yours) , and other techs stated a single pole was necessary if someone had a heat pump, which required constant power. To overcome this, a jumper wire is needed to provide constant power on the always on side. It would be great if you could explain this. You explain thing so well. Thank.
Excellent Video thank again for sharing. 👏👏👏💯💯
Thank you Miguel!! :) Glad you liked the video!
Thanks for the video =)
Jay THANK YOU so much for sharing your AC videos. They are enjoyable, informative and easy to follow. Your videos have tremendously enhanced my comfort level with the operation of my AC. So much so, that I am able to carry a conversation with an AC technician and not feel intimidated. I also feel confident enough to troubleshoot minor issues and/or make minor repairs. Thanks again, you’re the best.
I do have a question regarding single pole AC contactors. Is there a certain brand better than others or a brand I should steer away from?
Nice job 👍
Thank you so much i been watching your You tube !!

Great detailed video as always. You're the #1 AC/Furnace guy on youtube...hands down!
Thank you! :)
Great video my contactor had a big hole burned in the side, lots of corrosion and the plunger had fallen off. I think it must have exploded somehow. I’m going to install a new one tomorrow.
I honestly just took a picture of the old one and did it that way was pretty simple and fixed my ac unit. Just shut off the power first
