5 codes documented for Maytag microwaves
The humidity sensor used in Sensor Cook modes is not responding or is reading out of range. Auto-sensor cooking features will be disabled, but manual cooking modes will still work. The sensor is located inside the microwave cavity. Sensor replacement is required to restore auto-cook functionality.
A key or touch zone on the control panel is stuck or shorted. The microwave may not accept input or may behave erratically. Disconnect power for 60 seconds. If F2 returns, the touchpad membrane or the control board requires replacement. On some Maytag models, the touchpad and control board are a single unit.
The turntable motor is not operating. The rotating tray will not turn, causing uneven heating. Verify that the turntable coupling and glass tray are properly seated and not obstructed. If the motor itself has failed, it is a relatively low-cost replacement part accessible from the bottom of the microwave.
The power relay controlling the magnetron circuit on the control board has failed. The microwave may run (light and turntable operate) but produce no heat, or it may not power on at all. This requires professional repair — microwave high-voltage capacitors retain lethal charge even when unplugged. Do not attempt DIY repair on the HV circuit.
A general sensor error has been detected. This can indicate a fault with the humidity sensor, temperature probe sensor, or the door sensing switch circuit. The microwave will operate in a limited mode or may not start at all. Diagnosis requires identifying which sensor is faulted. Professional service is recommended.
