Dean for Model Number 2188159 The model number is for a defrost timer for my whirlpool refrigerator. It appears to be more than just a defrost timer as it has more than 4 prongs - is there a way to test this part to see if it has gone bad?
Answer Hello Dean. The best way to test if you are having a defrost issue is to test the heater and the defrost thermostat and see if they are good. If so, replace the timer 4388932. You can test for power coming to the timer, but without a model number we cant check the wiring diagram for this. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
