Error codeF40
ApplianceCooktop
Three parts are named behind F40 on a Maytag electric or induction cooktop: the user interface (touchpad), the power control board, and the wiring that goes with them.
Owner reset
Flip the cooktop’s breaker(s) to off and wait one minute.
Flip them back on.
Keep watching for one minute in case F40 appears again.
Check that the cooktop operates the way it should.
That is the whole list of owner steps in the Maytag help text for this code.
If F40 returns
A repeat after the reset is a service matter. The touchpad, board and wiring all sit inside the cooktop, so the next move is a technician visit.
Neighboring codes
F42: names the power control board and its wiring, without the touchpad.
For an F40 that survives the reset, reach the Bay Area team on (415) 649-2156 or read through Maytag cooktop repair. Have the cooktop model number, the code and your reset attempt ready so the visit can be planned around them.
Model compatibility: Maytag reuses codes across series and model years, so F40 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
F40 indicates a possible problem with the touchpad, the cooktop power control board, or the wiring between them.
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.
