The freezer coils develop frost in spring thru fall, in the winter they seem to be ok. Last year we changed the compressor for this problem. Now the problem is back with warm weather. Is there a solution to the build-up of frost that then ices up the coils?

ANSWER Hello Roy. The problem you are describing has nothing to do with the compressor but is a defrost issue. There is only a few components in this circuit: the defrost timer, the defrost heater, the defrost thermostat, and the wiring harness. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html The defrost timer 297318010 is mounted behind the kick panel and has a knob that allows you to advance it into defrost. This is the first test. Advance the timer into defrost,(you will know it's there when the fan and compressor kicks off). It should advance itself out of defrost in 30 minutes or less. If this happens, the defrost timer is probably good. Now the next test you need to open the freezer back wall,(after unplugging the unit to prevent electrical shock), and ohm out the heater 216730700 and the defrost thermostat 297216600. Whichever part you find bad will correct the situation and it will once again be a self-defrosting unit. Have a great day!
