Three codes, one KitchenAid description: the power control board or its wiring. A breaker reset is the listed step.
Model compatibility: KitchenAid reuses codes across series and model years, so F42 / F43 / F58 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
Possible problem with the Cooktop Power Control Board or its wiring.
One block of text serves F42, F43 and F58: the Cooktop Power Control Board or the wiring that goes with it may be the problem. Each code comes in an electric-only article and an electric-and-induction article, and the two never differ in content.
Start with a reset
Shut the breaker (or breakers) off for sixty seconds.
Put them back on.
Spend a minute watching to confirm the code stays away.
Verify the cooktop runs.
Why three numbers?
KitchenAid does not say why one description carries three numbers. Make a note of whichever appears, since a technician may find it useful.
If the code keeps returning
Described generally, the board is the part that manages power to the cooking areas. The articles contain no steps about cleaning, cookware or placement, and if the reset fails to stop the code they leave you with nothing else to try.
Before you phone
Check that your code is one of these three.
Be sure you waited the entire minute at the breaker.
Watch for the code throughout the monitoring minute and note how soon it comes back, if it does.
No separate test is offered for any of the three numbers.
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.
