Question about Jenn-Air Refrigerators

The refrigerator doesn't get cold. The condenser ices up. When I thaw it, it begins cooling again, but only for a few days at a time. What causes this and what do I do about it? Thanks, R. Scoggins

The refrigerator is supposed to self-defrost approximately four times in every 24 hour period. If one of the components in the self-defrosting system fails, the refrigerator continues to try to cool. Eventually, though, so much frost builds up on the evaporator coils that the circulating fan can't draw air over the coils. There may still be a small amount of cooling because the coils are icy, but with no air flow over the coils, cooling in the refrigerator compartment is quite limited.
Self-defrosting refrigerators all have a set of coils and a cooling fan, usually under the refrigerator, that need to be cleaned regularly. If these coils get coated with dust, dirt or lint, the refrigerator may not cool properly. The coils may appear to be a thin, black, wide radiator-like device behind the lower kick-panel. To clean them, disconnect the refrigerator from the power source, use a refrigerator condenser brush and your vacuum cleaner to clean the coils of any lint, pet hair, etc. You may not be able to get to all of the condenser from the front, it may be necessary to clean the remainder of the condenser from the rear of the refrigerator.

This is caused by the defrost system not doing it job .. there is a timer in some models and aditive defrost control in newer models . it knows when to defrost the frig . if it does not defrost properly the cold coil gets blocked with ice and stops the cooling . if the control ic not bad then the heaters may have failed and there is a defrost terminator that may also bee at fault . most common would be the heater / then terminator / & then the A D C. .. . hope this helped mm..

Why is my brisk air duo therm rv ac freezing up on the inside.


Where you see frost all the time, wait for unit to thaw and start cooling again and carefully slide hand up in that hole and see if you can feel cool air leaking in from divider that separates cool and return air, that will cause freeze-ups as well. Use foil tape if necessary to stop any cool air coming in to return air from around divider. Also, if you have any diffusers closed, (on ducted system in ceiling) or partially closed, open them all up full flow. If you restrict the cold air from coming out too much, it can also cause freeze up. One more thing, take cover off where cool air box is and double check that something isn't restricting the flow of cold in to the duct work if it has ducted system.

Hi, from my experience dealing with repairs of refrigerators and freezes, it is a fact that you likely have a bad condenser coil, condenser fan or condenser motor whenever your refigerator switches itself off and put it self on again. So you have to check one after the other to ascertain the faulty part and replace it...
