Error codeE24

Why E24 shows up
An over-the-range microwave that gets as hot as 500F (260C) inside the oven cavity reports E24. Whirlpool’s help article lists four candidates: thermal sensor, gas sensor, appliance control board, wiring.
Try this
Cut power at the breaker for one minute (unplugging works as well).
Turn power back on, then give it a minute to show whether E24 reappears.
Confirm that the microwave operates.
Where to look next
Read about E23, where the oven could not reach pre-heat temperature, or E11, a gas sensor problem. Both share part of the same component list.
San Francisco microwave service for a returning E24
When the overheat code returns, arrange a technician visit. Call (415) 687-4102; Bay Area owners should have E24 and the model number ready, along with what the reset did. More on Whirlpool microwave repair.
Model compatibility: Whirlpool 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.
Plain language
What this code means
E24 reports an oven overheat condition of 500F (260C).
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
