    My Whirlpool fridge is warm freezer works fine noticed the evaporator fan is not running , compressor is running and feels very warm
    For model number W8RXNGMWQ03
    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!

    My freezer and fridge are warm. I checked the evaporator the motor fan is running and i noticed a small frosted around the bimetal thermostat area. I replaced new capacitor, compressor start relay and overload protector and defrost timer. Now i am not sure defrost control board may need to replace?
    For model number ER8GHKXMQ03
    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!

    Freezer and refrigerator not cooling, i only had frost around the bi-mental thermost, i have replaced all of the defrost parts but still not cooling, i replaced the defrost control board first and after two days i could see that the freezer was starting to freeze then it stopped. What else could be causing my problem
    For model number t8txnwfwb01
    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!

    Loud click coming from thermostat cover. On/off sound. A day later i have frost built in freezer and bottom is not cold as it normally would be. I ordered a thermostat. Should i have ordered this part instead?
    For model number A8RXNGMWN00
    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!

        I unplugged the fridge.Removed the thermostat casing located in the lower part of the refridgerator by removing a few screws. disconnected the wiring plug from the relay board-connected the new board-screwed the new board inplace-put the casing back and replaced those screws. turned fridge back on and HOORAY off we went. i want to add frinding the part and recieving it so quickly was also part of a great savings to me!
