David,

It's easy to check if the 120 is coming on. Is yours in the generator bay or by the generator blower. Bleed the system pressure down to 60 by pumping the brakes. The compressor should come on. Put your hand on the compressor. It will vibrate when on. If it doesn't then, first check the breaker. You may have two breakers. One in the rear breaker panel, and a second one in the bay with the inverter. My coach is one serial number different from you. Newell did a neat thing on this one. They have a separate breaker panel for inverter loads, plus those loads can be plugged into the inverter or they can be plugged into AC feed that bypasses the inverter. They did this in case the inverter takes a dump, you can keep the frig and other things going without the transfer switch in the inverter until you fix it.

If the compressor doesn't come on, and the breakers are not tripped, then the next thing to check is to take a voltmeter see if you have voltage at the compressor. I don't know you and I don't know if you are comfortable with that or not. Please advise.
