What it means, first
Oven code E24 is the control reporting that the control saw the cavity exceed its documented ceiling and stopped. The control has already removed the heat, and leaving it removed is the right call until a technician has seen it. Nothing here needs a part until a genuine overshoot at the end of a clean cycle rather than a runaway heating circuit has been ruled out.
The code table for this reading
Reference| Code | Documented meaning |
|---|---|
| E24 | The oven reached an overheat condition of 500F (260C). There may a problem with the Thermal Sensor, the Gas Sensor, the Appliance Control Board, or the associated wiring. |
What an owner observes
- The oven got far hotter than the setting — Smoke, a burnt smell, or food ruined at a temperature that should have been safe.
- The code arrived during or after a clean cycle — The clean cycle is the hottest thing the appliance does and it is where overshoots surface.
- NEAR MISS - the oven never reaches temperature at all — That is the opposite fault and a different page entirely.
Causes in the order they actually occur
- A relay or switching device stuck closed — Ranked first because it is the cause that actually produces a runaway: contacts weld, the heat stays on, and nothing the control does turns it off.
- Thermal sensor reading low while the cavity climbs — Second: a probe reading under the truth lets the control keep calling for heat past the real set point.
The cheapest checks first
- Switch the appliance off at the breaker and leave it off — The first and most important action: it is the only way to be sure the heat cannot come back on.
- Look for scorching or discolouration inside and at the vent — Evidence of how far it went, and it changes the repair.
Steps you can take yourself
- Switch off at the breaker and leave the oven to cool completely — Isolating it is the whole owner-side procedure for an overheat.
About 60 min
- Write down the cycle, the setting and how far in it got — A stuck relay and a misreading probe need different parts, and this is what tells them apart.
About 5 min
- STOP HERE - do not clear the code and carry on — Unplug the appliance or switch off its breaker before any panel comes off; a capacitor can hold a charge after the power is off.
The safety line on this appliance
Safety
Isolate and let it cool. Unplug the appliance or switch off its breaker before removing any panel - a capacitor can hold a charge after the power is off - and remember that a heating circuit holds its heat long after the display goes dark. Never work around a thermal protection device: if one has opened, the restriction that opened it is the actual repair.
When a reset is not the answer
The free checks above come first; past them this is a visit. Call for this one rather than clearing it: an overheat means either the heat did not switch off when it was told to or the control was told the wrong temperature, and both are diagnosed with the appliance isolated.

The scope of this reading
Written for the model lines that shut the heat down at a documented ceiling, this page describes what the code means and how to work through it, nothing more specific. Part numbers, connector layouts and resistance tables differ from one family to the next and are not guessed at here. A family-level or model-level page, where one exists, is the better answer for your unit - the index below lists what is available.
