Error codeF4 E6
ApplianceWall Oven
Quick answer
A Maytag wall oven that displays F4 E6 may have a fault with the Microwave Wave Guide Temperature Sensor or with the wiring that connects it. Maytag lists the message for wall ovens in general and does not tie it to a particular series, so the same approach suits any unit.
Power-cycle routine
Turn off the oven’s breaker(s) and leave them that way for sixty seconds.
Restore the breaker(s) to the on position.
Keep an eye on the screen for one minute; the code should not reappear.
Confirm the oven runs normally to finish.
A message that shows up again after this routine means it is time to book a technician visit.
Codes worth comparing
F4 E3 is tied to the microwave exhaust air temperature sensor.
F4 E7 is tied to the microwave meat probe and its receptacle.
