Whirlpool Microwave Error Code F3 E2

F3 E2 means the control system has detected a shorted or open warming drawer sensor circuit. The important detail is that this microwave model is not equipped with a warming drawer, so the error points to a user interface board that does not match the appliance. Replacing the user interface with the correct part for the specific model is the standard repair.

A simple power reset is unlikely to permanently clear F3 E2 because the underlying cause is a hardware mismatch rather than a temporary software glitch. The error will return as long as an incorrect or faulty user interface board is installed. The fault must be resolved by replacing the user interface with the correct component.

If the repair requires only a replacement user interface board, parts typically range from roughly $50 to $150 depending on the model, with DIY labor being minimal. If you hire a technician, expect to add a service call and labor fee that could bring the total to anywhere from $100 to $300 or more. Getting a firm estimate before authorizing any repair is always a good idea.

A knowledgeable DIYer can address this error by entering Diagnostics mode using the OFF, OFF, START button sequence to confirm the fault, then sourcing and installing the correct user interface board for the specific microwave model. You will need to identify the exact model number to ensure you order the matching control. If you are uncomfortable working with appliance electronics, a technician should handle the replacement.

The F3 E2 error relates to a warming drawer sensor circuit rather than a core microwave heating or high-voltage component, but operating an appliance with an active control fault is generally not recommended. The incorrect user interface may affect how other features or controls respond. It is best to resolve the error before continued regular use.
