The first part of troubleshooting is knowing how it works. The relay under
the driver's seat only controls DC operation and that is only to switch
power to the 12 volt heater when the alternator is operating.  Of the 2
fuses behind the driver's seat, one is powered all the time and it feeds the
fridge cooling fan and the sink water pump along with the display. The other
fuse is powered from that relay and is for the fridge 12 volt heater. 

For the fridge to operate on 110 volts the power comes into the van, goes
through the circuit breaker, and then to an outlet in the pantry. The fridge
is plugged into that outlet. All the controls after that are on the fridge.
You have that rocker switch and the thermostat. 

I would just put the fridge back op propane when parked and use the 12 volts
for extended driving to get you through the weekend. 
Look for loose connections at the inlet plug and make sure the breaker is
not tripped.

Subject: Fridge Not Working on A/C - Relay?

Packing for a camping trip, and the fridge in my '87 Westy suddenly doesn't
want to get cold using A/C.  It worked at first, but then I switched it to
LP just to make sure it would light, and when I switched back to A/C it
didn�t get cold again. I don't hear the fan running either. The fuses behind
the driver seat look good. I'm thinking maybe it could be the relay behind
the driver seat? Is there an easy way to test or jump that relay?   I have
very limited time, as it's already 9 pm here and we leave early in the
morning. Looks like I may be bringing a cooler. :-(
