Quincy for Model Number rb1944sl Hello, I have replaced the main control board, both temperature sensors in the freezer and I'm having the same issue. The unit will get to the proper temp an will not start back up without being unplugged and plugged back in. We notice that there was ice on the coils in he freezer ad had to use a hair dryer to thaw the ice. It will run fine until the ice forms again! What could this be? Thank You in advance for your help.
Answer Hello Quincy. 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 Read More...
