Jenn-Air Microwave Error Code F6E5

F6E5 indicates that the microwave's control system has detected an incorrect cavity size configuration. The stored size setting does not match a valid expected value. This is a software configuration issue that is typically corrected through the System Info menu on the control panel rather than by replacing parts.

It is not recommended to operate the microwave while F6E5 is active. The cooking algorithms and power management routines depend on the cavity size setting being correct. Running the unit with incorrect configuration data could result in improper cooking behavior or other faults.

If the issue is only a misconfigured setting, a service call to diagnose and correct the cavity size through the System Info menu might cost anywhere from $75 to $150 depending on local labor rates. If the control board needs replacement due to a memory fault, total repair costs including parts and labor could range from $200 to $450 or more depending on the specific model.

Press the System Info button on the control panel, then navigate to Model and Size. Review the displayed cavity size and correct it if it is wrong or blank. Once the correct size is entered and saved, the error should clear. If the error returns after power cycling, the control board may need professional evaluation.

A simple power reset is unlikely to clear F6E5 because the error is tied to a stored configuration setting, not a temporary fault. The cavity size must be reviewed and corrected through the System Info menu. If the setting is correct but the error persists after a reset, a control board issue may be involved.
