Common fault codes for Maytag ovens include F1, which indicates a defective touchpad or membrane, and F3, which occurs when the oven temperature sensor is shorted or open.
A defective touchpad error or clock occurs when a function key is stuck. The best solution to this problem is replacing the touchpad or the clock if the touchpad is part of the clock. A shorted or open temperature error means that the oven temperature sensor is damaged. To fix the problem, replace the temperature sensor.
Additional fault codes for Maytag ovens include F2, which indicates that the oven is too hot, F5, which indicates wrong hardware and watchdog circuit connections, and F9, which indicates a door latch error. An oven too hot error occurs when the oven temperature is beyond maximum range or when the oven temperature sensor has a problem.
The watchdog and hardware circuits disagree if the wiring between them is not correct or if the clock assembly is damaged. A door latch error means that the wiring between the door latch and the switch is not correct or that the switch for the door latch is damaged.
