What E24 means

E24 on Whirlpool over-the-range microwaves, such as models WMH31017HS, WMH32519HZ and WMH53521HZ, means the oven reached an overheat condition of 500 degrees F (260 degrees C). The guidance says the thermal sensor, the gas sensor, the appliance control board or the wiring may be involved. The oven shuts down and shows E24 in the display. Because this is a protective stop, treat it seriously, and do not keep restarting the microwave to see if it clears.

Common causes of E24

  • Thermal sensor reading
  • Gas sensor
  • Appliance control board
  • Wiring and connectors
✓ One safe check you can try

1. Stop the cycle and let the microwave cool with the door closed. 2. If you smell burning or see smoke, unplug it or switch off the breaker and keep the door shut. 3. Once it has cooled, turn the breaker off for one minute and on again. 4. Watch the display for one minute. 5. If E24 returns, leave the oven off and call us.

! Why to stop there
  • We cannot say from the code alone whether the oven truly overheated or a sensor misread, so we test both.
  • Heat from a cooktop below can raise the reading, and we look at that as well.
  • We explain our finding and quote the price in writing before any work.
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.

E24E24 questions
Is E24 an emergency?

The oven shut itself down at the overheat limit, which is a protective response. If there is a burning smell or smoke, switch off the breaker and call us.

Should I reset it and keep cooking?

One reset after it has cooled is fine. If E24 returns, stop using the microwave until we have checked the sensors and control. Do not repeat this more than once.

Is it worth repairing an older microwave with E24?

Often yes if one sensor or connection is the cause, because those repairs are modest. We say plainly when the cost is not justified for your unit.
