My compressor will come on work but deforst heater will not work. I replaced heater but my coil still freez & heater will not work. Help////
Answer Hello William. 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
My freezer fan does not work nor defrost heater.also if the control board is bad will the compressor come on. My compressor come on but no fan or defrost ????
Answer Hello William,
The defrost heater will only come on when unit goes to defrost mode. You can check the fan motor by testing for 120vac, when the unit is running, across the leads. If you have 120vac then you have a bad fan motor. The most likely cause for both the fan and the heater to not work would be the Adaptive defrost control 5303918476. Check continuity on your heater as well to ensure that it is good. 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
