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 should add, PTC is a Positive Temperature Coefficient Resistor, so really PTCR. With no power applied, it's close to a dead short (low resistance). So in your case, it's if the Compressor Start Capacitor wasn't there and the wires were simply connected to themselves. When power's applied, it heats up fast and goes nearly open (very high resistance). That's why I said awhile ago that the PTC is equivalent to cranking your car for the same number of seconds without knowing if it actually started or when.
I mentioned I hadn't heard of a capacitor causing compressor noise. I wonder if it'd be noisy on its Start winding if it never shifted to its Run winding. Maybe from a failing/failed capacitor or PTC...?
Hopefully somebody who knows more about the electronic/electrical issues will jump in...
