If one electric burner will not heat, turn it off, let the surface cool, and compare another zone. Confirm the correct control and element size are selected. For radiant glass or induction, try a flat, compatible pan; induction needs magnetic cookware. If every zone is cold, check the labeled breaker once. Stop immediately for a cracked glass top, sparking, burning smell, or a breaker that trips again. Internal element, switch, and wiring checks belong to a technician.
One coil stays cold Likely cause: Loose or failed plug-in coil, receptacle, switch, or wiring fault. Homeowner action: Turn it off; after cooling, inspect only visible seating and damage.
One glass zone is cold Likely cause: Failed radiant element, control, limiter, or connection. Homeowner action: Try the correct zone and pan, then schedule service if unchanged.
Induction display says no pan Likely cause: Nonmagnetic, small, or off-center cookware. Homeowner action: Use a flat magnetic pan sized for that zone.
All zones fail but clock works Likely cause: Supply, breaker, connection, or control problem. Homeowner action: Check the dedicated breaker once; do not open the terminal block.
Element cycles off too soon Likely cause: Pan shape, temperature limiter, or sensor behavior. Homeowner action: Use a flat pan and compare the model's normal cycling.
Cracked glass or scorch marks Likely cause: Damaged cooktop surface or electrical connection. Homeowner action: Stop using the cooktop and arrange qualified service.
DIY difficulty: Low for checking zone selection, cookware fit, visible coil seating after cooling, and one breaker reset. Diagnosing an element, receptacle, switch, induction module, or wiring is professional work.
Estimated homeowner check time: 15 to 30 minutes.
Tools needed: Owner manual, flashlight, flat suitable pan, and a magnet if the cooktop is induction.
Safety risk: A surface can remain hot after the indicator goes out. Stop for cracked glass, scorch marks, arcing, or repeated breaker trips.
When to call a professional: The same zone stays cold with suitable cookware, a plug-in coil or receptacle looks damaged, or the breaker trips again.
