Customer Questions and Answers for Refrigerator Defrost Control Board by Whirlpool

Hello Dave. Look for loose connections. If none is found, replace the control WP2161460.

Hello AW, Based on the information, you want to check to see if your evaporator fan is running. If the fan is running but compressor is not Then you want to make sure that you are getting power to the compressor from the control board. The compressor circuit runs through the board. Check for 120 vac from White P4 terminal to Red on P2 pin 4. If you do not have voltage replace the board WPW10366605.

Hello Jim. Check and see if the bulb is loose. If not, then you need to look for a loose connection in the unit.

Hello Alberto. You will need to remove the control section in the top of the refrigerator to access the control board 8201672 in the unit. This is where you change the settings of the unit.

Hello Pernel, Yes sir, you are correct. WPW10366605 is the correct adaptive defrost control for the model number you listed.

Demetrios, Under the circumstances, you may want to start by checking the defrost system( heater, thermostat, and control board). The heater and thermostat are located in the freezer compartment, behind the back wall WP2323197 WPW10225581 and the control board is in the control assembly in the fresh food compartment WPW10366605, This is also where you probably should start. You probably have a short in the board circuitry, causing a short to ground and tripping the circuit breaker.

Hello Jim, The heat you are feeling isn't from a "heater" per say, but the heat from the sealed system backing up since it isn't dissipating the heat back into the room properly. You either need to clean the condenser coils with a vacuum cleaner, or the condenser fan motor W10124096 isn't running. Any time the freezer fan and the compressor is running, it should be running also. If it is running, you should try to stop the fan blade from turning. If you have to bump it to get it running and/or it is running slowly, it is bad and requires replacement.

Hello Chuck, Sounds like you need to replace the diffuser WP2209751. This is basically the little trap door that allows the cold from the freezer side to be shared to the fresh food side. If the spring has come off or the device has frost holding the little door in there open, it will turn the entire unit into a freezer.

Hello Dave, This unit has a defrost timer, not a control board. This unit either has a bad diffuser/damper or the evaporator fan motor has failed. If you hear the freezer fan when you open the door, the evaporator fan motor is good. I would check for a frost build-up on the back freezer wall. If there is no frost, you probably have a sealed system issue. If there is frost on the back wall of the freezer compartment, the unit is experiencing a defrost problem. Let us know what you find and we will go further in that direction.

Hello Mike, Sounds like a bad diffuser WP2209751, a bad fresh food thermostat WP2161460, Or a bad freezer thermostat WP2182770. Either the temperature in the fresh food side isn't coming down, (lack of air circulation...fan running so this would have to be the damper) or the temperature is coming down but the thermostat isn't responding as designed.
