Electric radiant cooktop zone does not heat at all (no error code)

Safety Warning

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

Burnt-out radiant element, Loose wiring at element terminals, Faulty infinite switch or power relay, Defective cooktop control board

How to Fix / Troubleshooting

Safety first: Disconnect power at the breaker before removing the cooktop from the countertop. Heating elements can retain heat; allow to cool.

Technician steps:

Access the underside of the cooktop and locate the radiant element for the affected zone.
Inspect wiring and terminals for signs of overheating or loose connections.
Test the element for continuity; an open circuit indicates a failed element.
If the element is good, test the infinite switch or electronic relay on the control board.
Replace the faulty element or control component as needed.
