So my 2002 Dometic refrigerator wasn't working the last time I was at my camper. I have it parked at a friends auto repair place out of town and use it infrequently we we come to visit. I did some checking and there was no 12V to the control board, the thermal fuse on the chimney was open. I reset the fuse and now I have light at the control panel but the check light is on also and no cooling. Fast forward to next weekend, I replaced the control board and now the check light stays off and I can feel the chimney is hot but no change in internal temperature after 3-4 hours.
So my best guess is something went wrong on the control board that forced the heating unit to stay on until it finally overheated the thermal fuse. I don't smell ammonia or see any signs of a leak but that doesn't guarantee there isn't one. Is it possible to overheat the chimney to the point it boils dry and requires some other action to recover it? I read somewhere else a suggestion to remove the unit, turn it upside down for 24 hours then set it back up.
