Induction cooktop shows F42 and the affected burner will not heat.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Open or shorted induction coil, failed coil temperature sensor, incompatible cookware, wiring issue to coil

Safety: Disconnect power before accessing internal components.

Verify cookware: Use a flat-bottomed, magnetic pan that covers most of the cooking zone. Test with a magnet on the pan bottom.
Try different pan: If F42 appears only with a specific pan, replace the pan.
Inspect coil (qualified only): With the glass top removed, inspect the induction coil for cracks, burns, or detached mounting. Check the coil harness connector.
Replace coil assembly: If the coil is damaged or open (no continuity), replace the coil assembly for that zone.
