Customer Questions and Answers for Bimetal Defrost Thermostat by Whirlpool

Hello John. First you will need to remove the basket and the freezer door from the unit. Once these are removed, you will then remove the icemaker from the side of the freezer compartment. Then remove the screws securing the back wall to the unit. In the center of the back wall there is a vent. To remove the vent, there is a clip in the slot on the bottom that needs to be released to remove the cover. Once you remove the center cover, you will need to remove the cover on the right side and remove the thermistor from the cover. Once all of this is removed, you should be able to remove the back panel and access the bi-metal WPW10165425.

Hello John. Yes, you will need to remove the back panel inside the freezer to access the bi-metal WPW10165425. It is located on the freezer coils.

Hello John. No, the control board WPW10503278 is located in the fresh food section inside the control panel.

Hello Mark. If the bi-metal WPW10165425 is cold, it should read closed. If it is hot, it should read open. The Bi-metal attaches to the top of the evaporator assembly on the large copper line. If the bi-metal and the heater test good, you will need to replace the control board WPW10503278. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter.
