Just put a new cooling unit on my propane fridge. What a PITA! Anyway, i have heard the real demise of these units is not using them. That somehow when they are not being used, it causes rusting and pitting on the coils. Is this true? Should i leave it plugged in at all times to keep the longevity or is it going to happen anyway? | ||

Bill - Re: "rusting and pitting on the coils" The metal generally rusts from condensation on the coils, and there shouldn't be too much condensation when the unit is off, right? When we were full-timing (in an RV), the new cooling coils rusted within a year of being in Florida; not all the way through, but enough to be noticed.. Then again, the brake lines rusted through after a year down here also. A new cooling unit we were given, had sat for years in storage prior to us getting it. It looked like new and preformed perfectly. I doubt either running it or leaving it off will make much difference, but there might be less condensation leaving it off.... John | ||

Since the coils are the condenser part of the unit, wouldn't they be warm/hot when operating? (and the evaporator part inside the refrigerator the cold part of the unit) Since condensation forms when the surface is below the dewpoint, keeping the unit running should keep the coils above the dewpoint and prevent condensation from forming.

They use amnonia for refrigeration instead of freon. The chemicals when under working conditions are the same effect. Taking hot air and putting it in a unwanted space. The problem is they have water in them also. and made of steel as they are will rust out regardless of where you are. They have rebuilt units available and they are about 1/2 price of a new unit. They are a bear to change sometimes you have to install it in the unit. They way to make sure the unit is bad is as follows. remove unit from wall. turn upside down for 24 hrs if possible lay on one side for 6 hrs lay on opposite side the same lay on back the same upright unit,and hook up a/c and check coils for heating, They will get real hot BE CAREFUL!! the element is normally about 150-150 watts at 110 v.
