Hello. Freezer coils frozen up. Can I do a forced defrost with this model refrigerator and can I test the defrost heater and thermostat for continuity from the adaptive defrost board or plug?
ANSWER Hello Phil. There is no need to force a defrost if it is not defrosting. The best way to find the problem is to remove the wall in the freezer and test the heater 67002493 and the thermostat 67003426 for continuity. They should read closed for continuity when cold. If both are good, then the control board 12002495 is bad and will need to be replaced. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
