2-way Norcold fridge only runs on AC power
Haven't started digging in yet, thought I'd throw it out there to see if this has happened to anyone before.
Started a two overnight trip, 2-way (AC/DC, no propane) Norcold DE0041 was running just fine on 12v. Went for a mountain bike ride, nice cold beer on return.
Friday afternoon and evening were cold and rainy / snowy, so we ran generator for a few hours enjoying "bonus" power and running furnace etc, fridge ran fine on AC power.
Shut generator off overnight, in morning everything quite warm in there. But fridge is still "on" on 12v, as in the light still works, and you can hear the fans and everything try to kick in when the thermostat tells it to, just the compressor doesn't start.
Went back to the generator, fridge still runs fine and compressor starts and runs on 110 AC. Ran the genny for a bit, made sure batteries were good and charged, then shut off AC power and tried fridge on DC again, same deal... lights are on and fans are running (so it's not the main fuse from the 12v fuse block to the fridge) but no compressor.
Anyone ever had this happen? Ideas of where to start troubleshooting? I looked at manual and wiring diagram and there doesn't APPEAR to be any fuses on the back of the fridge, but I fear this is heading towards pulling the whole thing out of the cabinet to diagnose.
Anyone know what these fridges actually run on natively (i.e. is it a 110v fridge and 12v is converted up, or is it a 12v fridge and the 110 is stepped down?)
