Over the last month I have taken the freezer apart several times and defrosted it. Because of my freezer working correctly and the refrigerator keeps getting warmer every day no matter where I set the controls. After about a week the fridge will not go over 50 degrees and the rear element cover is frozen hard. I noticed the damper door is not opening between the freezer and the fridge. How do I test to see which part is not working correctly? Is it probably the damper servo, thermister, defroster or something other? Thank you for your help and the websites Q&A is very important to me because I like to do most work by myself. Have a great day.
ANSWER Hello Steve. 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
