My freezer is working very well, the refrigerator however is too warm. The damper control door is working fine. The evaporator coils however are constantly freezing and not defrosting. The evaporator fan and everything else seem to be working fine. So I'm unsure if it's the thermostat, heater/defrost element, or the defrost timer.
Answer Hello Daniel. 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 fridge is no longer cooling.. seems like the fan is running and so is compressor but not getting any cooling. I was wondering if it could be either related to the defroist cycle being stuck open...
Answer Akrebs, Check the back wall of the freezer compartment, If there is a heavy build up of frost, ice or snow on the back wall, then the issue would be a defrost issue. If there is no frost build up, but there is no cool air entering the refrigerator compartment you'll need to check the auto damper 12571701 in the left rear corner to see if it is stuck closed or not opening due to a mechanical failure. At this point, it's not a failure of the ADC board.
