Error codeE12
ApplianceMicrowave
Seeing E12 on a Maytag over-the-range microwave? The code concerns the gas sensor or the wiring that goes with it. Maytag gives no further detail, only a reset and a recommendation to get service.
The reset, step by step
At the breaker, cut power to the microwave for one minute.
Restore the power.
Spend the next minute checking that the display stays free of E12.
Run the microwave to be sure it works as usual.
What a repeat means
If E12 shows again after the reset, a technician visit is the next move for the sensor and its wiring.

E11: also a gas sensor report, sent to the control board.
E24: a longer list of suspects that includes the gas sensor.
Our Maytag microwave repair page covers what a visit involves, and (415) 649-2156 reaches us for Bay Area bookings. Keep E12, your model number and the steps you already took within reach when you call.
Model compatibility: Maytag reuses codes across series and model years, so E12 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Maytag lists E12 for the gas sensor or its wiring, with reset and service steps only.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
