What F40
actually means.
F40 spans the whole control chain on a KitchenAid cooktop: the user interface, the cooktop power control board or the wiring that joins them. The code tells a technician where to start testing, not which part to replace.

What to do when F40 shows on the cooktopKind of codeBoards and communication
The touch board and the power board under the glass lost track of each other, or one failed its own start-up check. A power dip, a ribbon or harness pulled loose when the top was fitted, or moisture from a boil-over is ruled out before a board is replaced, and a cooktop that keeps heating while this code shows is switched off at the breaker.
Usually leads toTouch control repair
Glass touch keys and sliders that ignore a finger, start zones by themselves or stay locked, traced to the keys, the control board or the lock setting.
Shows up asCooktop Controls Unresponsive
Touch keys or a slider do nothing, the display lights but ignores every press, or a knob turns without starting its burner or element.

Before you book,
in this order.
Each step comes from KitchenAid's own guidance for F40 on its cooktops. Follow it to the end: the last card says whether this is a visit.
Switch the breaker off for one minute and back on.
Watch the display for a minute after power returns.
If F40 comes back, book a visit for testing of the touchpad, board and harness.
What not to do
F40 is not caused by cookware. It sits in the electronics under the glass.
