Do you leave your refrigerator on electric at a moderate temp setting for the months it is not being used...
I leave my refrigerator
on continuously for most of the summer and fall. However, if the camper is not going to be used for several weeks or more I turn it off, then defrost/dry the interior, and leave the doors open.
I have read reports from "refrigeration experts" who hypothesized that a cooling unit will last longer if the fridge is always on. This allows the anti-corrosion additive in the refrigerant to circulate and prevents sedimentation from depositing in the absorber and/or generator. I don't have any evidence to back this up, but it makes sense to me.
