E24 means the oven hit an overheat condition of 500F (260C). Sensors, the control board and wiring are named.
Model compatibility: KitchenAid reuses codes across series and model years, so E24 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
What this code means
An overheat condition of 500F (260C) was reached; thermal sensor, gas sensor, control board or wiring may be at fault.
An overheat message
E24 is KitchenAid’s way of saying the microwave oven became too hot, at 500F (260C). No owner cause goes with the message, only a short roster of suspects.
At a glance
| Code | E24 |
|---|---|
| What it means | An overheat condition of 500F (260C) was reached; thermal sensor, gas sensor, control board or wiring may be at fault. |
| What you can check | Cycle the power at the breaker with a one-minute wait, then watch for a minute to see whether the code returns. Confirm the oven is operating normally. |
| When to call a technician | If E24 repeats, have a technician examine the sensors and control board. Tell them whether the reset ever helped, since no owner test exists for the sensors. |
Suspects
| Item | Job |
|---|---|
| Thermal sensor | Measures heat and passes the value to the control |
| Gas sensor | An additional sensing component named for E24 |
| Appliance control board | Makes the oven’s operating decisions |
| Associated wiring | Links the other three |
The article offers these as possibilities, in no order of likelihood, and with no owner-level sensor test.
A figure worth noting
Because 500F (260C) appears in the text, E24 is less vague than many entries. Either the control registered that temperature, or a sensor fault made it believe so. KitchenAid leaves open which of those happened.
Listed steps
- Turn the breaker(s) off, wait one minute.
- Turn the breaker(s) on.
- Watch for one minute and see if E24 comes back.
- Confirm the oven is operating normally.
After that the article proposes scheduling service. A repeated E24 should be looked at by a technician who can examine the sensors and board.
