Maytag Microwave Error Code F2 E3

F2 E3 on a Maytag microwave indicates a keypad hardware failure. The control board has detected that the keypad assembly is not functioning correctly, preventing the microwave from registering user input. The fault can stem from a loose CN11 connector or a failed keypad membrane. Diagnosis should start by checking the CN11 connector and reseating it if necessary.

A power reset by unplugging the microwave for a minute or two may temporarily clear the display, but the F2 E3 error will return if the underlying keypad hardware issue is not corrected. Because this code reflects a physical component failure, a reset alone is not a lasting fix. The CN11 connector should be checked or the keypad replaced to resolve the error permanently.

Repair costs vary depending on whether the fix is a simple connector reseating or a full keypad replacement. If only the CN11 connector needs reseating, the repair may cost little to nothing beyond a service call fee, typically in the range of $50 to $100. If the keypad assembly requires replacement, parts and labor combined can range from $100 to $250 or more, depending on the specific model and local labor rates.

A knowledgeable DIYer can attempt to resolve this error by locating and firmly reseating the CN11 connector, which links the user interface to the keypad. If that does not clear the fault, replacing the keypad assembly is the next step. Working inside a microwave does carry electrical risk, so the unit should be unplugged before any internal inspection and caution should be taken due to the high-voltage capacitor inside.

When the F2 E3 code is active, the keypad is not functioning reliably, which means you may not be able to control the microwave properly. Attempting to operate an appliance with a failed input system is not recommended, as you may not have accurate control over cooking settings. It is best to leave the unit unplugged until the fault is diagnosed and repaired.
