Customer Questions and Answers for Bimetal Defrost Thermostat by Whirlpool

David, the defrost bi-metal WPW10165425 can be used with the model provided.

The following part number includes the defrost thermostat WPW10290745

Mike, The defrost control sounds like it would be the issue. The fan will shut off and on throughout the day but will go through defrost 3 times a day. If the defrost bimetal and heater check ok then the issue will be the timer.

Mark, This issue would be caused by a faulty defrost circuit. You will want to test the defrost thermostat and the defrost heater for continuity. If either does not have continuity then replace that part. If they both check good for continuity then replace the defrost control which will be part number WPW10503278.

MLM, The only way to get the defrost bimetal cold enough would be to get the temp down to 15 degrees. If you stick it on the evaporator with the unit running for 24 hours and then test it before installing.

Hello John. No, you need to order WPW10165425 for the defrost thermostat.

Hello Ray. You need to check and see if the control board W10219463 is bad and is not sending power to the fan motor. 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

LGR, To answer the first part of the question on the defrost bi metal. Coming off the actual bimetal there should be 2 wires. The orange wire will split off to 2 wires and one will go to the heater and the other to the control board. If you cut the thermostat out at the 2 wires right at the thermostat then you can splice the new thermostat in place. For being able to access the control board on the refrigerator you would remove the light cover, once the light cover has been removed, if you look up behind where the lights would be, you will see an opening on each side. Using a flat blade screwdriver and put it into the slot and push toward the front to release the control board housing. This will allow access to the control board for you.

Hello Alberto. The control board is number 6 in this diagram link. http://www.appliancepartspros.com/control-parts-for-whirlpool-ksra25cnss00.html

Hello Richard. Based on the information you provided, if the unit has to be manually defrosted to clear the ice off the coils, you will need to order and replace the electronic control WPW10503278 in the unit. It is bad and is not going into the defrost cycle like it should and will need to be replaced. This is used as the defrost timer for this model.
