My Refrig. is freazing up in the back of freazer, starting to run all the time, is it the Bimetal defrost that controles this or the module part 2169337? If its the Module where is it located?

E. Davis for Model Number 106.9750383

ANSWER Hello E. Davis. You will need to test the heater 2315530 and the bimetal 4387503 and make sure they are good. They should read closed for continuity when cold. If one of these are open, they are bad. If they both are good, then you will need to replace the defrost timer 2183400. It is located inside the control assembly. You will need to remove the screws holding the control assembly in place to access the timer. You can test the heater and bimetal with a multi-meter TJMA-DM1. 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
