Still learnin' ...

We have such a refer in our 5th wheel. Runs on either propane or 120
VAC shore power. Type of power to use is selected by push button at
the top of the unit. You didn't say which was being used when your
unit stopped. If it was using propane, did the propane bottle run
empty? Did the "fault" light come on?

Each year before we start camping, I pull the outside cover and blow
all the dirt, spiders and other stuff out with compressed air. Lots of
stuff comes out!

The units run on ammonia gas and if this leaks out, the cooling stops.
Have you smelled any ammonia in your camper? Well, you said you
haven't inspected the unit, so I guess you wouldn't know, yet.

Hard to guess until you know more.
