What E13 means

E13 on a Whirlpool over-the-range microwave, including models WMH31017HS, WMH32519HZ and WMH53521HZ, means the oven did not pre-heat correctly. The guidance says there may be a problem with the appliance control board or the wiring connected to it. You will see E13 in the display after a cycle that was supposed to heat the oven, and the cooking program stops. This code is about the heating start-up, so food may come out cool.

Common causes of E13

  • Appliance control board
  • Wiring and connectors to the control board
  • Heating circuit that should bring the oven to temperature
✓ One safe check you can try

1. Switch off the breaker that feeds the microwave for one full minute. 2. Switch it back on. 3. Monitor the display for one minute to make sure E13 does not return. 4. Start a preheat or short cycle and see that the oven behaves normally. 5. Make sure nothing is blocking the vents above and below the microwave.

! Why to stop there
  • A reset cannot show whether the control board or the heating circuit failed to start the preheat, so we test both.
  • If E13 comes back on the next preheat, the cause is still present.
  • You approve the written price before we replace anything.
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.

E13E13 questions
What does it mean that the oven did not pre-heat correctly?

The control expected the oven to warm up and it did not. The guidance points to the appliance control board or its wiring, and we confirm which by testing.

Is E13 dangerous?

The oven stopped to protect itself, so it is not an emergency by itself. If you smell burning or see smoke, stop using it, switch off the breaker and call us.

Do you repair older over-the-range models?

Yes, many older units are still in homes across Houston. We repair them and say plainly when the cost is not worth it for your microwave.
