Maytag Microwave Error Code F1 E1

F1 E1 indicates an oven user interface failure. The microwave's diagnostics have detected that the control panel board is not functioning correctly. This fault points specifically to the UI board, which handles button inputs and display functions. The code will persist until the UI board is confirmed functional or replaced.

Start by cycling power to the unit and then entering Diagnostics Mode to verify the active error codes. Check that any ribbon cable connections to the UI board are fully seated and free of damage. If the fault persists after these checks, the UI board itself needs to be replaced, as it is the component identified by this specific fault code.

If the fix requires only a power reset, there is no parts cost involved. If the UI board needs replacement, parts costs typically range from $75 to $200 depending on the specific model, with professional labor adding $100 to $200 on top of that. Getting a repair estimate before proceeding is worthwhile, as the total cost relative to the microwave's age should factor into the repair decision.

A power cycle is the first recommended step and can clear the fault if it was caused by a temporary voltage irregularity. Unplug the microwave or shut off its circuit breaker for at least one minute, then restore power. If F1 E1 returns after the reset, the UI board has a persistent failure and will need to be replaced.

A UI board failure means the control panel may not respond reliably to inputs, which makes normal operation unpredictable. It is not advisable to continue using the microwave until the fault is resolved. Attempting to operate the appliance with a failed user interface could result in unintended behavior or commands not being processed correctly.
