Questions & Answers

For Frigidaire Refrigerator User Interface Control Board (Part Number: OEM21052191)

1 Answer

Hello Michael, the variable speed compressor on your model is powered by an inverter board and controlled by an input signal from the main control board telling the inverter how fast to run the compressor. There is a possibility the generator output has damaged the main control board or the inverter control board.

Gary, With the damper having been replaced it would be recommended to test the thermistors in the unit to make sure that they are good. The thermistors would have a resistance reading of 5K ohms at room temperature. If the thermistor is good then the issue will be with the main control board.

Mickey, You will want to check to make sure that the crushed/cube solenoid next to the auger motor is not stuck in the up position. If it is then it would need to be replaced. This would be the most common cause other than ice build up behind the door in the crusher bin that opens for the cube ice. If that has occurred then look for an air leak around the ice door on the dispenser.

Jerry for Model Number FGHF2366PF5A

The LEDs on the user interface assy many are burned out this is the second time this has happened. The refrigerator is only 5 years old, the first time it happened it was less than a year old and was covered under warranty. Within a year of the new interface replacement, I noticed LEDS on the temp numbers going out and I do not leave the display on. Now the LED's indicating water, cubes or crushed are out. Is this an indication that the whole board is failing or just the LED? I don't want to send $150.00 just for the convenience of knowing what is going to come out in my glass.

Jerry, it is likely that the issue could be simply that the LEDs of the user control 5304527930 are failing which would be considered a control failure. However, it could not be guaranteed that the LEDs are all that would fail or if this would have an impact on the proper operation in the future. It is usually recommended to replace a control when an LED is failing because of the inability to guarantee the failure only going so far.

Tim, Based on the model number provided you must hold the lock icon for three seconds to turn on or off. If this does not work you may have a user interface board that has failed. UI part# 5304527930

Jason, It is possible for the dispenser control board to be faulty causing the unit to turn the icemaker off. The dispenser control will definitely need to be replaced.

Bob, The trigger for the icemaker to call for water will be part of the icemaker itself. With what has been replaced this may be an issue with the water valve on the unit.

Bill, Underneath the front of the display there will be 2 screws. Remove these screws and remove the piece of trim at the bottom of the display. There will be 2 screws behind this trim piece. Remove the screws and pull the bottom of the display and it will come out.
