Error codeF40
ApplianceCooktop
Three places F40 can come from
Whirlpool Product Help lists F40 for electric, radiant and induction cooktops and names these possible sources:
the user interface, which is the touchpad;
the cooktop power control board;
the wiring associated with them.
What the owner can try
Turn the circuit breaker off, or unplug the cooktop, for one minute, then switch it back on and see whether F40 returns. Checking the touchpad, the board and the wiring is technician work.
F2E1: control or wiring, with key cleaning advice.
F40 repair in San Francisco
If the code comes back after a power cycle, have a technician look at it. Whirlpool cooktop repair is where San Francisco visits are explained, and (415) 687-4102 takes calls. Keep the model number nearby.
Model compatibility: Whirlpool 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.
