Pulled into a campground late last Thursday and hooked up. Put the refrigerator on AC; the inside temp was just under 40 degrees at the time.

I woke up next morning to a warm box. I lighted the propane without changing the thermostat and it cooled right back down to 40 degrees.

I checked the circuit breakers, none were popped. I also plugged the TV on the same circuit and it worked fine.

I haven't had time to look further. I figure it is either a failed AC heating element or a bad AC thermostat.

I'll run it on propane for this next rally and then let the dealer figure it out along with fixing a couple of other small items.

I had same problem with my old Dometic.

To change heat strips I had to remove reefer from its holding position. Heat strips are not expensive but a pain to do.
Lucky for you on Dealer work.

It's a beautiful day here in central Texas.

I'm bringing the trailer home today to wash and Walbernize Super-Seal it for the winter. While it is here, I'll do some probing with my multimeter. I have a gut feeling it is the AC thermostat and not the heating element that is at fault.

In fact, I'm outa here right now.

I put the meter across the heating element and turned the refrigerator on AC with the temperature selector to "on" so that the element should be on all the time. No heat! I then found that I had no voltage to the control box in the fridge.

There is an double AC outlet, out of sight in the outer wall above the lower refrigerator vent. I plugged in an extension cord in the unused socket, the circuit tracer into the cord, and had voltage. I then moved the refrigerator cord to that socket and, voila, I had voltage and heat.

I checked the original socket that the refrigerator was plugged into and it seemed to be intermittent. The socket I moved the refrigerator to seems to be solid as a rock. I'll just leave it there since the refrigerator would have to be removed to change the outlet.

Another bullet ducked!
