There's a "Converter/Charger" somewhere in the coach. It Converts 120vac (if you're plugged into 120vac or running a generator) to 12vdc. That 12vdc supply takes over for your coach battery for MOST of the lights and appliances that use 12vdc. The trick here is "MOST." It isn't uncommon to find the fridge logic board powered directly by the coach battery. So it's possible the fridge's control system might not be powered up if you're plugged into 120vac but your coach battery is missing or dead. The Charger part is supposed to recharge the coach battery when you're plugged into 120vac. The Charger side (or Converter side) can fail and the other side be good. Charger fail, coach battery won't charge (or will run down if installed new or charged), fridge still won't run.
You need a Digital Volt Ohm Meter (DVOM, aka Multimeter) and start checking for 12vdc.
Coach (or House) battery may be underhood, very possibly in part of the coach body, sometimes cleverly hidden. There should be 12vdc and 120vac power/fuse/breaker panels, much more likely inside the living space of the coach than under the hood.
