A/C Not blowing Cold Air

Thanks team!

The diagnosis from the tech was that the compressor winding was showing continuity to the AC case, so they are saying it's shorted.  I'm planning on confirming this diagnosis soon when I can get back on the roof.

I was looking at replacements, and yes, 800-1000 seems to be the going rate, would probably be worth just swapping it at that point.  I didn't notice any schrader valves to check pressure of the unit - is that a thing on RV A/Cs?

Thanks again,
