Dometic fridge generating heat while off

Thanks for that info Doug. The part about the ambient temp switch brings memories back from years ago when staying in an RV on a construction job and temps were staying down below zero for weeks at a time. Someone figured out if we put a 40 watt light bulb behind the fridge under the coils it would work. Hoar frost would form on the door knob on the inside of the RV at about 20 below when cooking.
