Hello!

I recently bought a 15,000 btu window unit Off of Craigslist. The seller stated that the unit was two years old and did not cool as well as it used to and possibly needed a “recharge”. Once I installed the unit I came to realize that this unit was not cooling whatsoever, Essentially just functioning as a fan even when I’m cool mode. The unit it perfectly clean as if it were brand new, however I cleaned the filter anyway as this is all I know how to do in terms of A/C maintenance and repair. After a bit of research I am wondering if maybe the compressor is broken? The unit is very quite and really only sounds like a fan, so maybe the compressor is not even turning on at all and that is my problem? Or is there a way to “recharge” the air conditioner?

Has anyone had any experience with this unit before? And what does this sounds like/how do I fix it DIY?

Thank you!

Sorry I forgot to put the brand of A/C. It is an Amana 15,000 BTU 115v. Model AMAP151BW.

If the compressor and both fans are coming on and it's not cooling, get rid of it - not worth fixing, leaking refrigerant or other major issue.

If the compressor isn't coming on, it could be something simple like a capacitor and is worth checking out.

Always test used appliances before buying!

Window shakers aren’t really intended to be serviced. Unless it’s a high end unit, it’s likely built as a disposable appliance.
That’s not to say you can’t work on them. But you’ll need the proper tools.

Can check still check the capacitor and see if power is being applied to the compressor.

If it's a bad board or has refrigeration problem, the unit is junk with labour cost exceeding that of buying a new one.

Absolutely.
I should have been more specific with my post. Every window unit I’ve seen is a sealed system with no access ports to test the refrigeration circuit.
Exterior parts can still be easily tested.

I favor units with mechanical controls - one less proprietary thing to break.
