Dometic Refrig Defrosting

How much ice should you let build up on finned surfaces before you defrost.

Any ice will have some impact on the efficient cooling of the fridge.
The more ice build up the less cooling and the softer your ice cream

Make sure you have the drip pan hose outside the camper's access panel (and not INSIDE like mine was delivered) and the pan is completely under the fins and then:

If on battery and propane (like boondocking) turn off the fridge for an hour; then check. They should be clear; then turn the fridge back on.

If on Campground (shore) power, just make sure the "climate control - defroster" switch is on and it will do this automatically. TURN IT OFF before you go back on battery. The heater that warms the fridge air to defrost is 12VDC and will kill your battery quickly.

Sounds like this is Refrigerator specific, on our Georgetown the refer automatically defrosts ever 48 hours, also the drain line does not protrude out of the rig, it is fastened so that it drips through the lower vent. Our old rig would frost up like crazy and we defrosted about once a month by removing everything from the freezer and use a blow dryer and dull knife to clear the ice.

Sounds like Sherry's been leaving the doors open too much. :-) Donna says you should defrost as soon as there's ice build up. She decreases the effectiveness of the freezer. I would think where you are that all you'd have to do is open your door and store it outside. Safe travels and our best to you, Sherry, Gary & Ruby.

When my refrigerator starts freezing up, I turn off refrigerator and use a hair dryer to defrost the build up ice. Then turn on the refrigerator and it takes about 1 hour to get back down to 36 degrees. and will maintain that until it freeze up again. I had a refrigerator tech tell me that. No need to remove food from refrigerator. Now when I defrost the freezer, then I remove all food. Good luck. I am full-timing and a workamper and enjoy it.
