Refrigerator Defrost Board 4388931

Hello Russ, thank you for your question! If the fridge is warm, but the freezer remains at the proper temperature AND the evaporator fan motor is not turning you should replace the Evaporator Fan Motor part number WPW10188389. Please enter the part number into the site for current price and availability. Good luck with your repair!

Hello Minh, Thank you for the question. I suggest testing the Clip-On Bimetal Defrost Thermostat with Leads. The best way to do this is to remove the thermostat from the refrigerator so you can control the temperature of the sensor. You can let the sensor warm up to room temperature. With the sensor warmed up to room temperature the sensor should read approximately 6.2K Ohms at 68°F. With the thermistor submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms. If the values that you are getting are far off from these readings, then the sensor is bad and should be replaced. Hope this helps!

Hello Staunchis, thank you for your question. We would recommend testing the Part Number: WPW10662129 Capacitor. Usually if the fridge and freezer stay warm, it has something to do with the capacitor on the compressor. I hope this helps!

Hello Robert, Thank you for the question. If the sound is coming from the Thermostat, it is more then likely the issue. Hope this helps!

Hello Mike, thank you for reaching out. We have researched the model and found that the issue might be with the Defrost Heater, part number PS11739991.
