Appreciate your informative professionalism. We're hard pressed to find someone as valuable as you and I thought I'd let you know.
Thank you for the kind words
Thank you so much for your help. You have help me fix my air conditioning unit to cool my dogs when it’s 100 Degrees outside. You are absolutely a lifesaver thank you so much.
Thank for watching Rex have a blessed day
Congrats on restoring a basket-case! One landfill is smaller due to your diligent efforts. But we sure could use someone like you here in N. Centr. FL. Messages sent to top ac repair and manufacturer (Frigidaire) for a year-old unit I installed last Aug. that just stopped cooling. So far: *Crickets * -Only deafening silence from all concerned. Except the fan motor. Outside is 78° inside is 83°! House is well-insulated and holds heat! No one here works on window units. *sigh *
They make little tools that fit almost any fins per inch pattern for straightening fins. I forget what it cost, but it wasn't much for the hassle it saves. Especially if you are doing multiple units. it does several fins at a time.
Very sharp!! Good job figuring this out.
try a flea comb next time to straighten out the coils it works awesome and saves so much time. i try to work smarter not harder. thanks for this video. it helped me out alot. my husband said we should throw it out and i said no i like fixing things by myself without having to ask him for help. Your video was very helpful.
Flea comb that's a great ideal thanks for watching and keep fixing stuff I'm working on a dishwasher tonight.. there's always something to fix.
@@ktoutdoor RIght!! Like no one should ever be bored. Theres so much to do. Lol Again thanks God bless you. Keep up the great work!!!
Thank you so much for this video, and for covering so much information, it's helped me out a ton!
Thanks for letting me know it helped you.
this video is awesome and you explain so well!! I feel like i can do this!! both my window u it's stopped blowing cold air. I wonder is there some other product I can use to get the crud off since I don't have any type of acid just laying around under my cabinet. Thank you so much for this video sir, you have given me confidence to try.
Sure any real strong clean like simple green will also work, let it soak for a good while then blast it with a good stream of water be sure to spray straight on into the fins if you come at them sideways they will bend if you need any help just call or text me 606-875-0125 Kevin
@@ktoutdoor where do the rest of the wires go? And y do I need a cap if I’m wiring it direct?
You did a great job with that
The compressor on Our window ac unit just recently stopped coming on too.. Been meaning to pull it out of the window and look at it.
Hi,guys! Just cleaned my wall unit. I was carefully to not get water to the control panel or any electrical parts. But still not starts. I can hear a little buzzing noise but neither the fan or compressor starts. I can use the control panel ,shows temperature, mode etc but that's all. Any idea? Could be the capacitor got little bit of moisture? Appreciate any thoughts
Yep the relays in those things can fail really easily. For some reason it seems condensation or moisture finds its way into the circuitboard, and since the relay isn’t sealed… It gets into the coil and starts to corrode those tiny wires in the relay coil. You can easily pop the relay open once it’s off the board and fix the relay usually even with corrosion… i’ve seen this exact failure mode a dozen times on these boards. Just a little bit of corrosion creeps up the legs of the relay and corrodes the tiny coil wire disconnecting it from the leg. Also the small voltage regulator in the TO 220 package can get hot and overheat/go bad
Thank you for contributing.
Yes and that happens the SAME WEEK the warranty runs out!
Bought & installed my Frigidaire one year ago (Aug.) and last week this happened.
Am not an electronics expert and here in N.Centr. FL NO ONE does work on window units.
My dogs and I are about to die of heat stroke. Thank You Frigidaire! Wish you were here.

Same here! Frigidaire AC, 1.5 years old. Hot dogs. Been working on it for the past few weeks trying to figure out what is wrong. Replacing parts as they arrive. Have yet to figure out. Hoping today is the day.
@@dreamsnchains4830 My "part" arrived just the other day: a brand new air conditioner by Midea, top-rated and more power. Some $300+ with free shipping via Amazon- but worth it. Out with 6,000 in with 8,000 BTU's. LR is now a cool 73-74 degrees and dogs are resting comfortably.
Am now the proud (scsm) owner of no less than SEVEN window ac units, ONE of which is working. (To be fair four are antiques with outdated coolant so that leaves three)... And hoping to repair the other two including the one just referred here. Because always you need backup... so THIS never happens again.
How do you tell if compressor works or not? Mine is in the window, can't take out. It blows but it is not cool air. I cleaned filter, then cleaned back and front. But it will not blow cold air. Is there a simple way to check if that thermo thing works in front for temperature and to see if the compressor comes on?. Mine runs, blows air but I dont know if the compressor is working. Thanks any quick testing for a female would be great. I took the front off and cleaned like I said. I just cannot swing a new a/c window unit. It's a fridgidair 5,000 btu w/ electronic controls. It's a bedroom a/c unit. Ithittimg 100 plus here now. :/
Awesome job!!!
Thanks for watching
How do I find someone in my area who can do this kind of work? I have a three yr. old window unit 18,000 btu's and it stopped cooling. All the hvac people I've called won't even consider working on it because the "Labor and parts would be more expensive than a new a/c unit." I don't have your skills but you make it look so simple and I hate to get rid of this a/c when it could be fixed. Btw, we already pulled it out of the wall and cleaned the coils front and back and hosed it out. The temp. sensor is in place.
Any one that does electrical or radio repair computers? someone that can read a wiring schematic can figure it out.
I have a ge 11900 btu that’s blinking and beeping if u type that in the search bar there’s a guy showing the same problem and thousands of views ,ge said they are sending me a check and said they don’t make them anymore but it’s only 6 months old and wondering if u know anything to help fix it. It seems like a waste to just throw it away
I have an Amcor PCMB10000EH Portable Air conditioner. I turn it on turn temp to lowest setting and compressor won't kick on since nothing is coming out of back exhaust. It also has a heater on the ac. i crank that to 90 degrees. compressor still doesn't kick on. it only blows room temp air on cold and on heat temps. it' not using the compressor just the reg fan is all that is engaging. My question is does this machine have a relay switch and where will it be located. and does it have a fuse and where is it located? I'm having issues. Please help me so my machine compressor can start working. Would low coolant, cause a compressor to not kick on? I have tools. I just need help please. I can't find tech support anywhere. i will pay for a fix. i have all tools. i need help please.
I have the same Samsung unit. It worked last time I used it. This year not so much. I opened up and looked around. The compressor clicks once heats up a little, then clicks off. I am stumped.. Any help is appreciated
Could be a capacitor or a bad compressor? watch this for more info czcams.com/video/vsozg8W2tes/video.html
Great video
Thanks for watching
I have less than 3 year old through the wall ac which stopped blowing cold air. The fan runs fine but it hums for 3 sec and then stops. And it.does it again. It can't seem to start the compressor. What could be the problem? The relay or the compressor? I called a repair guy and he asked for 400 bucks on the top of 175 initial diagnostic. I'm trying to fix it by myself before I get a new one.
Could just be a bad capacitor = cheap fix or could be a locked up compressor watch this fist then test the capacitor or remove it and take it to any local HVAC store they will test it for you. czcams.com/video/SihpkALJtmE/video.html
@@ktoutdoor Thanks Kevin! Will check it out. Have a good day!
Using this technique there is no thermostat control, correct? It just keeps cooling until you unplug it? I wonder if there's a way to get some sort of thermostat control wired in. Thanks for your video!
Yes you can and I have done this in the past you will need a standard house hold thermostat a 24 volt power supply and a 24 volt sequencer then tie it into the compressor wire so you can cycle the compressor on and off. call me if you need help hooking it up 606-875-0125 Kevin
Thanks!
whew 56*?? send it right over, my Whirlpool just crapped its logic chip out the board too.
Fair play to you..well done,
Mine has no starter relay. And it says. "NOTE: the illustration is explained the wire connection of the O.T.P of the external compressor. For the internal compressor, the O.T.P has been connected with the compressor." What's this mean?
Over-Temperature Protection it works like a fuse if compressor gets to hot it breaks the connection try a quick bypass and see if it works then buy a new otp
Just for your info. This looks to be a Samsung unit. When you first turn this unit on, there is a 5 to 8 minute delay before the relay closes to start the compressor. I found my first one of these and tnought control board was bad, but after i turned it on, and set temp low as it would go, i let it sit and run and compressor started after about 8 minutes.
Thank you for contributing.
Where could I find a schematic for mine? And r u in KY like I am?
Yes Somerset
Took it apart and got it working today. Apparently It developed a loose connection and it was not turning on the compressor. Fan was coming on but the compressor would never kick on at all.
Awesome you got it working!!
Good job to get someone's junk working again
Kevin. My names Daniel and I have 3 little kids, and where I live it is getting very hot. My window a/c compressor is getting hot and I can hear it trying to kick on but it wont. Can u help me please.
call me if i can still help you 606-875-0125 Kevin
It looks to need some anti-rust coating spray on the chassis
Why ac cmpressor have been stop running
Kevin what if the compressor trys to come on and sit there and gets hot?
That could be a bad capacitor or the compressor could be locked up. Remove the capacitor and go to any HVAC supply store and get it tested if bad replace it and hopefully that will get it going. plus discharge the capacitor with a screw driver.
@@ktoutdoor Thank you very much i will check it out my brother.
@@ktoutdoor Yes sir it was the cap, thank you much my brother. its blowing cold, i clean the coils with good cleaner.
@@kevinhoney1385 Thats great news.. Now go fix something else...lol
@@ktoutdoor Amen brother
Will it hurt anything to bypass the relay
No problem I do it all the time
did you check the fuse?
Yes, it was good probably a bad circuit board
I cleaned mine and now the compressor will not shut off at set temperature. Please help it is freezing 🥶 I think the electrical got wet. Everything else is working great, the display works, wifi and everything. The unit is only a year old Toshiba 10k btu
I may take a while for the board to dry out
How long did the ac last you after fixing it??
Amazing but its still working !!
@@ktoutdoor well I have one just like that. I've had it 13 years now. All of a sudden the compressor stop running . I had capacitor checked and it's good. Cleaned it to.. so I tried your technique and compressor still didn't Come on but it runs. So I took the cap off of compressor to check the wires and behold the wires had burned up but terminals are good and shiny. So now I'm replacing the wire and clips that are on the compressor. Your fan in front is different then mine. But this is a good air conditioner for having it 13 years I never new about cleaning it till now. I'm hoping if I replace the wires compressor will come on if not I can't complain for having it 13 years.
@@vickirichardt2344 Thanks for sharing your story I sure hope you get it going, Have a blessed day Vickie
When I pulled the cap off compressor there are wires that go to the terminals and there like this little round thing under the cap as well that is connected to the black wire. Do you know what that is and what it's for??
@@vickirichardt2344 Thermal Overload Protector try by passing it to see if it will come on. also watch this czcams.com/video/_iICWI4lV5U/video.html
I have a GIBSON air conditioner
Mine is making a loud noise on cold as the temperature goes up can anyone help
Give me a call 606-875-0125 Kevin
Can you just kinda let me know if it's worth fixing or I could send you the sound it makes tomorrow
Lots of possibilities most are simple.. sure send me the sound.
Can’t help but notice there is a fuse on that circuit board
I watched your video, you seems failed to mention what is failed? You doubt the relay yet measure it is working. So, what's your problem fixed? did I missed anything? anybody can comment?
Going by memory it was either the relay or most likely something on the circuit board that I cannot repair those circuit board
s are bad about going bad I fix them a lot them by doing this bypass.
Low talker , I had to pull out a amplifier. Speak Up.
Will do
isnt it gonna ice up the evap after the room startes getting cooler? the compressor has to cycle off but you have it on always?
Only if the the unit was low on refrigerant, allowing the the coil to fall below 32 degrees. Or if it was a very small room and really got cold.
I found my schematic, just cant red it!? Lol and cant send u a pic. Do u have email address so I can send u a pic. I need to wire mine like yours.
i can text it to you my cell 606-875-0125
