Freezer defrost problem

Posted by mamalinda (My Page) on

Hello,

Our freezer/refrigerator stopped getting cold enough last week. The freezer was freezing ice, but not ice cream or other foods and the refrigerator was running at about 55 degrees.

I checked to see if it was a defrost problem and sure enough there was a lot of frost built up all around the coils and even on the back of the inside of the freezer.

I've now unplugged and defrosted the whole unit. I originally suspected it was the defrost timer. But now I'm thinking that the timer is not the problem because when I manually turn the timer till it "clicks" and the compressor goes off, the defrost heater does not warm up.

Is it still possible that it's the timer? Or should I think about replacing the defrost thermostat? Or is there something else I should be looking at? Is it possible to test the thermostat if I don't have a multitester?

Thanks so much!

Linda

RE: Freezer defrost problem

You'll have to do further investigation on the individual components ... suspect the defrost heater first, then the thermostat, then the timer.

Note that the defrost thermostat must be cold to trigger the heater. The heater can't come on if the unit is still "warm" after you unplugged it for manual defrosting.
