KitchenAid narrows F42 to the cooktop power control board or its wiring. That board switches power to the zones, so a zone may not heat, or may behave oddly, while F42 is active. KitchenAid cooktop display What to do when F42 shows on the cooktop ### Kind of code Boards 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 to Touch 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 as Cooktop Element Not Heating A coil stays black, a radiant ring under the glass never glows, or a zone warms so weakly that a pot of water will not boil. ### Make KitchenAid A Whirlpool brand with cooktops aimed at people who cook often. ### Source KitchenAid Product Help: F42, electric and induction cooktop KitchenAid electric and induction cooktops. ## Before you book, in this order.

Switch off the cooktop's breaker for one minute. If it comes back, it needs a visit. ### What part does F42 point to on a KitchenAid cooktop? The cooktop power control board or the wiring connected to it, according to KitchenAid's page. ### Should I switch the breaker off if a zone keeps heating with F42 showing? Yes. Any zone that will not switch off is a reason to cut power at the breaker right away and book a visit. ### Can a KitchenAid zone stop heating while F42 is showing? KitchenAid ties F42 to the power control board that switches power to the zones, so a zone that stays cold or acts oddly while the code shows fits the picture. --- **[Read on the site: KitchenAid cooktop showing F42 | CooktopRepair.center](https://cooktoprepair.center/error-codes/kitchenaid-f42/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
