What this codemay mean.
A plain-language reading of the code — always confirm against your model’s documentation.
Mean
There may be a problem with the Sensor, the Appliance Control Board, or the associated wiring.
Whirlpool’s help article connects E63 with the sensor, the appliance control board or their wiring. The control board received a shorted-condition report from the oven sensor circuit.
Models covered: over-the-range microwaves.
Reset sequence
The reset: breaker off, or plug out, for one (1) minute. Once the minute is up, bring power back. The manual then asks you to monitor the microwave for one (1) minute. Make a final check that it works.
If it comes back: Still stuck on E63? A qualified technician can check the sensor, the appliance control board or their wiring.
