Error codeF3 E7
ApplianceWall Oven
Possible causes behind F3 E7
Three items could sit behind this message on a Maytag wall oven: wiring, the sensor that measures temperature in the lower oven, and the control itself.
What you can do at home
Go to the breaker panel and shut off the circuit for the oven. A minute of no power is what is wanted.
Restore the circuit.
Stand by the oven for a minute and confirm F3 E7 does not light up again.
Check that the oven runs normally.
If the code is back after that, have a technician come out.

Booking wall oven repair in the Bay Area
From San Francisco to the rest of the Bay Area, Maytag wall oven repair starts with a call to (415) 649-2156. Say that F3 E7 is showing, give the model number, and describe the reset you tried.
Model compatibility: Maytag reuses codes across series and model years, so F3 E7 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
F3 E7 lists associated wiring, the lower oven temperature sensor or the control as the possible 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.
