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...

So I was able to locate the service manual online for my unit.

It details how to discharge the capacitor. It also mentioned a PTC:
Positive Temperature Coefficient Thermistor
(PTC) (Start Thermistor)
It doesn't show what it looks like but I recall seeing a little black canister in the control box with the capacitor. If it is, I guess I have to test and/or replace that too.
Since Carrier no longer makes or service these units I will post post the Owner Manual and Service manual for others. I will do it in a separate thread.
