Error codeE22
ApplianceMicrowave
A short in the thermal sensor circuit
Seeing E22 means the control board of a Whirlpool over-the-range microwave was informed of a short in the thermal sensor circuit. Whirlpool’s suspects are the sensor itself, the board that reads it, and the wires between the two.
Power reset, in order
Switch the breaker off, or pull the plug, and leave it that way for one minute.
Bring power back.
Stand by for a minute and see if E22 returns.
Run the microwave to confirm it works.
Codes close to E22
E21: the same list of parts, for a different circuit report.
E62: a sensor, control board or wiring problem on the oven sensor side.
E23: the oven did not reach pre-heat temperature within thirty minutes.
Over-the-range microwave service in San Francisco
If E22 comes back after the reset, a technician visit is the next step for a Whirlpool microwave in San Francisco or elsewhere around the Bay Area. Ring (415) 687-4102 with the code, the model number and the result of your reset; the details are on Whirlpool microwave repair.
Model compatibility: Whirlpool reuses codes across series and model years, so E22 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
