Error codeE63
ApplianceMicrowave
The oven sensor circuit has sent the control board a shorted-condition report, and an over-the-range Whirlpool microwave answers with E63. The help article names three suspects: the Sensor, the Appliance Control Board, and the wiring.
Steps to try first
Shut off the breaker that feeds the microwave, or unplug the unit, and wait one minute.
Turn the power back on.
Spend one minute watching for the code to return.
Run an oven function to verify operation.
A code that comes back means a technician visit.
Codes worth comparing
E62: sensor, control board or wiring, with a short in the oven sensor circuit.
E61: the same three suspects, with an open circuit.
E21: a thermal sensor entry that is easy to confuse with this one.
San Francisco microwave repair
For a Whirlpool microwave in the Bay Area, dial (415) 687-4102 and have E63, the model number and your reset notes in front of you. The microwave page is Whirlpool microwave repair.
Model compatibility: Whirlpool reuses codes across series and model years, so E63 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
E63 points to the sensor, control board or wiring after a short in the oven sensor circuit.
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.
