Error codeF1 E4

Understanding F1 E4
The function the oven was asked to perform did not happen, and F1 E4 was the result. On Maytag over-the-range microwaves, the appliance control board or its wiring may be responsible.
Do this first
Switch the breaker(s) off for sixty seconds, then on again. Keep the microwave in sight for one more minute and make sure the display stays clear. Then check that it runs.
Reset did not help
If F1 E4 appears again, book a technician rather than waiting it out.

For a Maytag microwave in San Francisco, ring (415) 649-2156 or read Maytag microwave repair. Give the technician F1 E4, the model number and a note of what you already did.
Model compatibility: Maytag reuses codes across series and model years, so F1 E4 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
The oven could not execute the function; the appliance control board or the associated wiring may be at fault.
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.
