Hello. Frost buildup in freezer, fridge stays warm. I've replaced the defrost timer and still have the problem. Before I order the defrost thermostat, I want to check with my digital ohm-meter. Do I need to remove the thermostat to do this test? Can I just touch the 2 thermostat wires with my leads and get a reading without removing it? Also, if it is an "open" reading (meaning a faulty part?), does that mean I am getting numbers greater than 0 on my ohmmeter? Thank you.
Answer Hi Bob. The defrost thermostat in frozen temperatures always ohms out closed (0-Ohms). Usually 15° or so. Then it also needs to open as temperatures raise so it shuts the heater off and not melt the cabinet. The element needs to measure resistance and not open (infinity). These are best to change together since they are electrically in the same circuit and they work 24/7 along with the same age. It is a bit of time it takes to defrost the coils (manually) and install all parts. The heater and defrost thermostat can be measured with one wire disconnected as long as there is no power going to it. Heater part # 5317842502. Thermostat part # 5303917954. Thank You.
Freezer is freezing up and not defrosting cause bottom to warm up and not get cold.
Answer Hello Nancy. Test the heater and the thermostat. They should read closed for continuity when cold. If they are good, you will need to replace the timer if there is a defrost problem. 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
The freezer works good, but the refirgerater does not get cold. What can I do to fix this? I have cleaned the coils in the back and the inside. Mike.
Answer Hi Mike. A few scenerios. Is the evaporator fan motor/ blade turning up to speed? The motor is part # 218878801.The fan blade is part # 5308000010. The damper needs to be opened mid way to get cold air to the Fresh Food cabinet.This part # is 218722200. If your evaporator coils continue to freeze up, Then I would replace the defrost thermostat part # 5303917954. Thank you.
