What E11 or E12 means

E11 and E12 on a Maytag over-the-range microwave and hood combination both point to the gas sensor. With E11, the gas sensor reported a problem to the control board, and with E12 there is a problem with the gas sensor or its wiring. This is the sensor that helps the microwave judge cooking steam, not a sensor for household gas. You will see the code in the display, and sensor-based cooking may not work properly.

Common causes of E11 or E12

  • Sensor not giving the control a usable reading
  • Wiring or connector to the sensor
  • Control board input for the sensor
✓ One safe check you can try

1. Cut power to the microwave at its breaker for one full minute. 2. Turn it back on. 3. Monitor the microwave for one minute to see whether the code returns. 4. Verify the microwave works by heating a cup of water for a short time. 5. Use timed cooking in place of sensor cooking until it is checked.

! Why to stop there
  • If E11 or E12 returns, the sensor, its wiring or the control may be involved, and only testing shows which.
  • We check the sensor circuit before replacing any part.
  • We quote the repair in writing before work, and we say so plainly when an older microwave is better replaced.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E11 or E12E11 or E12 questions
Does E11 mean there is a gas leak?

No. The gas sensor here belongs to the microwave and helps it judge cooking. It is not a household gas detector. If you ever smell gas, leave the house and call the gas utility from outside.

What is the difference between E11 and E12?

E11 means the sensor reported a problem to the control board, while E12 means a problem with the sensor or its wiring. The first owner step is the same.

Can I use the microwave?

Often yes for timed cooking, once the breaker reset is done. Sensor cooking may not work until we test the circuit, so watch the food and use the timer.
