Inline fuse on the compressor wiring (if your coach has a Thomas TA-4101-DC compressor). If you have the smaller compressor I don't think you have this fuse.

The white panel of 12V breakers in the basement (if you're not familiar, it's hard to tell they are breakers).

Also, the pressure switch.  Found the following topic which was also for a 2001 coach.

Pulled white cover in bay. 15 amp breaker? labeled HWH COMP test hot on red side with copper buss bar connecting all breakers nothing on white side (out) with 12v tester. Bad breaker? Where can I get? Anything I should know about taking out? Line out is C18. It should test hot on both posts, correct?

You most likely just need to reset that breaker. Get your flash light and look real close at that breaker.  you will see a little button that is popped out. Some are white, red, or black and I have seen breakers with all those colors. When you find the reset button just push it in with a pencil or popsicle stick.    Now give it a test and report back.

Will look tomorrow for reset. At dinner with son that lives in Orlando for his birthday.  FOGO DE CHAO Brazilian meat overdose. Wil probably be working with meat sweats tomorrow. If can't reset and breaker is bad will be readily available at Napa?

They most likely won't have one on the shelf but will be able to get it overnight.  i have found them at O'r, Autoz, and CrowB.

Maybe easiest fix yet. Found reset button on breaker, pushed and voila compressor started pumping.  BTW what should high limit shut off be set at. Thanks again for all the sage advice and tips.
