Whirlpool E24 on a microwave: 500 °F (260 °C) overheat

Risk level
High
Professional inspection is recommended.
Urgency
High
Quick answer
On a Whirlpool over-the-range microwave, E24 means the oven reached an overheat condition of 500 °F (260 °C). If you see smoke or flame, keep the door closed and cut the power; then reset the unit as Whirlpool describes.
Safety first
Stop and check this first
- If you see flame inside, do not open the door: switch off, cut power at the breaker and wait for it to die out.
- An over-the-range microwave is not taken apart to check boards or wires: the high voltage capacitor can keep a lethal charge even with the power off. Magnetron, door seals and safety interlocks are for authorised service only.
Safe checks you can perform
- Smoke, flame or burnt food
- Breaker off for one minute
- Short, watched test with a load

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Thermal and gas sensor measurement
What they doThe authorised technician measures the thermal sensor and the gas sensor and checks their wiring against the service manual values, after discharging high voltage.
They must show youboth sensors' measured values against Whirlpool's specification.
In writingthe values, the cause and the part number of anything replaced.
Inspection after overheating
What they doIf there was smoke or flame, the technician checks the cavity, the door and its latch before declaring the unit fit for use.
They must show youthe state of the cavity and the door.
In writingwhether the unit is fit for use and what was checked or replaced.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Smoke, flame or burnt food
- Who:
- you, without opening the door if you see flame.
- How:
- look through the glass. If there is flame or heavy smoke, keep the door closed, switch off and cut power at the breaker.
- Result that matters:
- whether there is or was fire or smoke inside.
- If there is flame or smoke:
- wait for it to die out and do not use it again until service has checked it.
- If no sign of excess heat:
- move on to the breaker cut.
- Evidence to keep:
- photo of the cavity and a note of what was cooking and for how long.
Evidence: E24 - Error Code - Over-the-Range Microwave
Breaker off for one minute
- Who:
- you, at the breaker panel and without opening the unit.
- How:
- switch the microwave's breaker or breakers off for one minute, switch them back on and watch the display for another minute, as Whirlpool says.
- Result that matters:
- whether E24 reappears within that minute.
- If it does not return:
- let it cool and test with a short load.
- If it returns:
- Whirlpool points to service to check sensors, board and wiring.
- Evidence to keep:
- time of the cut and whether the code came back during the minute.
Evidence: E24 - Error Code - Over-the-Range Microwave
Short, watched test with a load
- Who:
- you, with a microwave-safe container of water.
- How:
- with the unit cool, place a microwave-safe container of water inside and set a short time. Stay in front of it. Do not run it empty.
- Result that matters:
- whether E24 returns without excess heat.
- If it does not return:
- the code came from that cooking.
- If it returns after a short time:
- it points to a sensor or its circuit; ask for service.
- Evidence to keep:
- note of the time set and when the code appeared.

What it means
Whirlpool defines E24 as the oven reached an overheat condition of 500 °F (260 °C), and names the thermal sensor, the gas sensor, the appliance control board or the associated wiring as possible origins. It can be real heat or a false reading from one of those sensors. The code does not separate them: whether there was smoke or burnt food, and whether the code returns after cooling in normal use, does. The page is Whirlpool US's over-the-range microwave guide; confirm the code in your model's manual.
Warnings and stop conditions

Symptoms and causes
Probable causes · in order
- Real heat inside the ovenPossible
This is the condition Whirlpool describes. It fits if there was smoke, charred food or a long cooking time before the code.
Evidence: E24 - Error Code - Over-the-Range Microwave
- Thermal sensor or gas sensorPossible
Whirlpool cites both sensors. If E24 appears after a short time with no sign of excess heat, it points to a false reading.
Evidence: E24 - Error Code - Over-the-Range Microwave
- Control board or wiringLess common
Also cited by Whirlpool. They are considered when the sensors measure fine and the code keeps appearing.
Evidence: E24 - Error Code - Over-the-Range Microwave
