One radiant, coil, or induction position remains cold while the other cooking zones work. Because cooktops combine high heat with high-current electrical parts—and some models also involve gas—the appliance type must be identified before service.
Common causes
- The element, induction coil, or temperature limiter has failed
- A selector switch, relay, or power-control module is not supplying the zone
- A terminal, connector, or wire is loose or heat-damaged
- The cookware is not being detected on an induction model
How the problem is diagnosed
A technician confirms the element type and cookware requirements, then checks the zone circuit, element or coil, limiter or sensor, switching device, wiring, and control output. Testing identifies whether the fault belongs to the replaceable cooking zone or the shared electronic module.
This article concerns electric cooktops and the electric cooking functions of combination appliances. The diagnosis and an upfront estimate are explained before approved work begins.
Information to prepare
Record which zone fails, whether an indicator appears, and whether the problem changes with different compatible cookware on induction models. Keep the model and serial number available; they are often printed on the underside or in the installation documentation.
Repair or replace?
The decision depends on the failed control or element, parts availability, glass condition, installation access, and appliance age. A serviceable switch or cooking zone may justify repair, while cracked glass, unavailable electronic modules, or multiple heat-damaged components can make replacement more practical.
