Ac unit inoperative Gmc.

[Misfitted]

Hello everyone and thanks for your time.

I'm having a bit of a issue with my ac unit.
First I'll give you the back ground info.
I bought the house last year (in the middle of winter)
The house is strong and we'll put together. Have had little to no issues out of it....
The ac unit is a gmc? Last Saturday the unit would not fully come on. The top fan would engage but at only 1/4 of its normal speed....
I messed with it a bit and got no results. Finely I let it set for several hours... when I started messing with it again I checked the fuse box of the house.... that's when I found two brakers (linked together on a slide) I noticed one was thrown and the other was set.... I rest the two together and boom everything was working great again....
Everything was great until yesterday. Same issues.... this time no thrown braker.... ):.....
Iv checked everything I can think of. Iv replaced the capacitor with a new one (locke supply) verified it was the correct one... 27$.

Symptoms are -
Top fan spins slowly (1/4 speed)
Every 3 mins or so you can hear a (grrring) sound from the compressor. the noise will last roughly 10 secs and then remain silent for 3 more mins. The noise sounds like the system is trying to fire up.

These are the same issues I had the first time... only after I changed the capacitor the noise increased in sound a little.
I'm a single working dad with 2 boys. I need to get the cool back into my home. I don't have much to to research and throw money around....
Anyone have any suggestions. Thanks

Hi there!

It sounds like you're dealing with a frustrating situation with your AC unit. From what you’ve described, it seems like there might be a few issues at play. The top fan spinning slowly could be due to a problem with the fan motor or an issue with the capacitor, even though you’ve replaced it. It’s worth double-checking that the new capacitor is the right one for your unit, but if it is, the fan motor itself might be the culprit.

The grrring sound from the compressor suggests that it’s having trouble starting up, which could be related to a failing compressor, a faulty start relay, or potentially low refrigerant levels. If you haven’t checked the start relay or overload protector, these components are relatively inexpensive and might be worth a look. However, if these parts seem fine, the compressor itself might need attention.

Since you’ve had issues with breakers before, it’s also a good idea to check the breaker panel for any signs of wear or damage. Persistent breaker problems could indicate an underlying electrical issue that might require professional attention.

In the meantime, make sure all connections are secure, clean any dirt or debris from the unit, and verify that the capacitor is installed correctly. If these steps don’t resolve the problem, it might be best to call in an HVAC professional who can provide a more thorough diagnosis and get your system running smoothly again.

Hopefully you have already fixed the issue!
