I'm aware of the need to keep the fridge level. We run it on propane
going down the road but my understanding is that's ok because of the
jostling it gets. Other than that, both of us are very sensitive to NOT
having the coach level, for sleeping or cooking eggs, so I can guarantee
that it doesn't get parked off level. Ever. If driving with it on can
cause this crystallization then I'm guilty.

I've had the cover off the breaker box but never messed tightened
screws. I'll do that.
But there are no issues here at home on my 30A circuit and I've never
had this problem anywhere else. I recently wired in a 120V plug (half
of the socket is Short power, half is 700A Inverter) to the bedroom and
tapped off the Microwave plug for that Shore power. The only thing
plugged into it was my wife's new CPAP machine and just turned on, NOT
running. Microwave clock went out with a "beep" and after unplugging
the CPAP didn't come back on for a couple hours. FWIW, I am pretty good
with the AC wiring stuff. Almost positive I didn't do it wrong. And as
I said, it works here at home.

Thanks for the input, Emery.

Eventually the microwave would come on (hours later?) and would work fine as long as you didn't plug a toaster in. That circuit works just fine when plugged in at home. Was the 30A circuit at the campground below 110V, perhaps? Could that have friend the control board on the Refer?

It sounds like you have been operating it off level and the return tubes from the freeze section are likely clogged with ammonium crystals.
If so, there is very little that you can do except replace the cooling section or the whole refrigerator.
This is a common problem. You should level the motorhome to within 1/2 o a bubble on the little round level that came with the refrigerator.

As to your electrical problem, take the cover from your breaker box and (with the shore plug unplugged and the Onan off) check all the screws holding the wires inside the box.
I suspect that you have some loose wires. Over time the screws will loosen with the heating and cooling of the wires. I helped someone whose air conditioner kept cutting off. We found several wires loose in the circuit breaker box.
After tightening them everything worked OK.
