Before You Call a Technician

The majority of induction cooktop problems are resolved by one of three actions:

Run the magnet test on your cookware — if it doesn’t stick firmly, the pan is the problem, not the cooktop

Induction cooktop troubleshooting first step - refrigerator magnet test on pan base, if magnet slides off the pan is incompatible not the cooktop, resolves majority of not-heating complaints — Run the magnet test before anything else — if it doesn’t stick firmly, the pan is the problem. This single check resolves the majority of “my induction cooktop isn’t working” service calls.

Perform a full power reset — turn off the dedicated circuit breaker for 5 minutes, then restore power

Induction cooktop power reset - turn off dedicated circuit breaker for 5 minutes then restore power, resolves most error codes and sensor faults without service call — A full power reset resolves the majority of error codes — turn off the dedicated breaker for 5 minutes, restore, and test.

Check the control lock — many cooktops have a lock function that disables all controls and is easy to trigger accidentally

If none of these resolve the issue, the error code on your display is the fastest path to a diagnosis. → [Error Code Reference][/induction-cooktop/problems/error-codes/](updating)
