What E23 means

E23 on a Maytag over-the-range microwave and hood combination means the oven did not reach the preheat temperature within thirty minutes. The manual says there may be a problem with the heater, the appliance control board or the wiring. You will see E23 in the display, and the oven or convection function stops. Microwave-only cooking may still work. We repair these combination units, including older ones still in many Houston kitchens.

Common causes of E23

  • Heater not producing enough heat
  • Appliance control board
  • Wiring or connector in the heating circuit
✓ One safe check you can try

1. Shut the breaker feeding the microwave and leave it that way for a full minute. 2. Turn it back on. 3. Monitor the microwave for one minute to see whether E23 returns. 4. Verify operation with a short microwave-only test using a cup of water. 5. Keep the front and top vents clear of items.

! Why to stop there
  • A slow preheat can come from the heater, the control or the wiring, and the display does not say which.
  • We measure the heating circuit before replacing a part.
  • You see a written price first, and we tell you honestly when an older unit is not worth the repair.
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.

E23E23 questions
What does thirty minutes mean in E23?

The control waits up to thirty minutes for the oven to reach preheat temperature. If it does not get there in that time, the oven stops heating and shows E23 on the display.

Is E23 a safety risk?

The message is about too little heat, not too much. Even so, do not keep running the oven function if the code returns after a reset.

Can the microwave still be repaired?

Usually yes. We test the heater and control, quote the price in writing first, and say plainly if replacement is the better choice for an older unit.
