Do you have a defrost timer for this refrigerator and where is it located? I have ice build up on the coils and both fresh food and freezer sides not cooling well.
Answer Hello L.D.,
The defrost is controlled by an electronic board 12106802 on this model. Unfortunately, it is no longer available. It is inside a metal box mounted to the bottom of the unit, accessed from the front.
What circut is the Thermistor part of? If it is bad will it stop the defrost mode
Answer Hello George. No, the thermistor W10331672 is used to sense the temperature inside the unit. It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the back wall of the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
