Maytag Oven Error Code F6E5

F6E5 means the oven's control board has detected that the stored cavity size setting is incorrect or missing. This is a configuration fault, not a mechanical failure. It is resolved by accessing the diagnostic menu, going to SYSTEM INFO then MODEL AND SIZE, and correcting the value using EDIT CAVITY SIZE.

F6E5 is a configuration error that may affect how the oven manages cooking functions and temperature calibration. Using the oven while this error is active is not recommended, as the control system may not behave as intended. The error should be corrected before resuming normal use.

If the fix only requires reprogramming the cavity size through the diagnostic menu, the cost is typically limited to a service call fee, which generally ranges from $75 to $150 depending on your location and the technician. If the control board itself is faulty and unable to retain the setting, board replacement can add $150 to $400 or more in parts and labor. Most F6E5 cases do not require any parts.

Correcting the cavity size setting requires entering the oven's service diagnostic mode, which is typically accessible only with knowledge of the specific button sequence for that model. While the fix itself is software-based and does not require parts, most homeowners will need a qualified technician to navigate the diagnostic menu and enter the correct value safely.

A simple power reset, such as unplugging the oven or tripping the circuit breaker, will not resolve F6E5 because the underlying cause is a missing or incorrect setting in the control board's memory. The correct cavity size must be entered through the EDIT CAVITY SIZE function in the diagnostic menu. If the setting is not corrected, the error will return after every power cycle.
