My system works fine for a few days then the evaporator freezes up and then both side won't cool properly. What you think it may be?
Answer Hello Miguel. You will need to test the defrost heater 242044113 and thermostat 5303918214. They should read closed for continuity when cold. If they are good, you will need to replace the defrost timer 5303918340. 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
