Window AC Not Turning On or Cooling - Most Common Reason Why

Is your window air conditioner not turning on or turns on and the fan is running but its not cooling? In this video I show you what the most common problem is and how you can fix it. Most window AC units will have a capacitor in them which happens to be the part on an air conditioner that fails most often. Luckily it is not hard to replace and doesn't break the bank. In this video I show you how to find, test, and replace a capacitor safely and quickly.

Thanks Jay for another informative video! Love your tutorials! Capacitors are definitely curious components, sometime they will work forever and other times they expand and die. They always seem to be the weak link in the system on any A/C unit.

YOU STILL DOING SUCH A GREAT JOB THANK YOU SO MUCH

[andresbarragan]

FROM CHICAGO IM SO GLAD I HEAR ABOUT YOU

[s.j.]

Glad to see you are still making videos Jay! I finally got my EPA 608 certification after taking a HVAC class at the community college. The course was dirt cheap compared to all of the A/C equipment I bought to service my own. If I can keep my units going, or make sure a new one is installed (& charged) correctly then it is well worth it!

Great job as usual ... They finally showed that movie in our town ... It ran and ran for days Aloha my friend

Hello 👋 🫂 good buddy Jay 👋 it's good to see you today buddy 👍. I'm visiting my brother today and his window unit isn't wanting to kick on the compressor and buddy this video is perfect timing 👍 I'm going to take his unit out and take it home and fix it now because you just learned me some very valuable information. Luckily I have some ol scrap units at home I can use for parts..I hope you all are doing well 😊 I'm doing pretty good for a ol dude ..lol. tell everyone I said hello 👋 🙂 and give them a big old fashioned hug 🫂 for me please 🙏 ❤❤❤❤much love to you all.

How about one that runs for awhile and cools, then turns off, then cools, rinse and repeat. This is for a through the wall unit. As well, is there temperature cut off for these, when it gets to hot to run. Having this issue now during a heat wave, where it short cycles

😂😂 nice joke jay.... its another Thanksgiving table joke 😂

I offer you respect and gratitude for the information you provide on this useful channel, and I thank you very, very much with deep appreciation for you and your information.❤❤❤

The other simple repair you can make is replace the fan motor, that has a shaft that drives both fans for the evaporator and condenser. but I must admit you will find parts on these units hard to find and expensive, so if the unit has any age just buy a new one.

Hi there . I live in Greece and discovered your channel, and i have being watching your videos to find the problem with my A.C. but i didnt so i would like to ask your opinion to tell me the possible reasons for the problem . So my A.C. when i turn it on it burns the fuse . But when i removed the capasitor and started the A.C., it worked without burning the fuse . So i thought it was the capasitor and i changed it but again it burns the fuse .My suspicions go to the compessor and/or the electronical circuit board of the A.C. outside .What do you think ?

[garymcmullin]

I don't have any statistical observations to refute this idea but perhaps so. The compressor relay can also be a problem and my favorite is the printed control circuits on todays units, the incorporate resistors, transistors, diodes, etc that can and very often do go bad. Chinese origin of all these components including the start and run capacitors means a high percentage of early failure. Electronics out of China is a real gamble. Best bet for the homeowner is to have one of the small units, 5000-9000btu capacity in back up to install if you do have a breakdown because repairing the problem is going be considerable in comparison to the cost of a new unit.

I watched an older video where you installed a hard start kit and you were surprised that it didn’t make a difference. The same thing happened to me, can you think of a reason why?

[Dicofol]

Where would put condensate treatment pills or tabs inside the window's A/C unit to prevent the moldy smell that always develops over time ?

[SRD]

I have a midea portable, and thought the compressor was broken, but i opened up to find the compressor terminal was disconnected from the capacitor, and now the compressor boots up and cools my room as it should of, funny times lol.

[alexandershilling]

Do you know what else can damage the air conditioners hail from severe thunderstorms?

[bnrz]

I replaced capacitor and still nothing. What else should I try. And also it isn’t loud how it used to be

[it_geek]

I don't understand so what was the issue then if capacitor was fine?

[johncalla]

These new window air conditioners are junk. They last for about one season then their cooling ability drops off a cliff.
