Carrier A/C Compressor making a humming noise
The Carrier A/C on my 2006 Jayco Greyhawk is making a buzzing noise. I'm getting ready for a trip and afraid my a/c may go out in the summer heat. Carrier A/C model is 68RV15102A Here is a video...

I take it you tried the Fan Only settings and no humming sound then?
It IS cooling, right? Air flow seems normal?
You can run the compressor BRIEFLY with fan disconnected and confirm the noise. Are you sure the outdoor fan blade and inside blower wheel are tight and undamaged?
We had a Coleman that made noise because one of the shock mounts at the base of the compressor got out of place.
Noise also possible if refrigerant lines get to rubbing, against each other or against the cabinetry.
I don't know if a failing capacitor can get the compressor out of phase enough to make noise but capacitors are cheap.
Have you worked on 120VAC equipment? And with Capacitors? If you haven't you'll need some coaching and a Helper/Safety Observer.
Two suggestions:
1. Update this thread with Model Number of the A/C. Maybe we can find a wiring diagram to show how to temporarily disconnect the Fan, and how the Capacitors are connected.
2. Click "Notify Moderator" and ask to move the thread to Tech Issues. This A/C is used by all RV types, and more techy OP's hang out there.
