Induction Cooktop Won’t Recognize a Pan? Check the Cookware First

Induction cooking feels almost instant when it works, which makes it stand out immediately when a zone stays cold and a pan icon flashes instead. The good news is that this particular complaint is usually about the cookware, not the cooktop.

Because induction zones heat through the magnetic base of the pan itself rather than heating the glass surface, a pan that is not compatible simply will not register — no matter how new or well-maintained the cooktop is.

The magnet test settles it quickly

Hold a refrigerator magnet against the base of the pan in question. If it grips firmly, the pan is magnetic and should work; if it does not stick, or barely holds on, that base will not couple with an induction zone.

Aluminum, copper, and some stainless cookware without a magnetic layer will not work on induction even though they perform perfectly well on gas or radiant electric cooktops.

Placement and settings matter too

Even compatible cookware needs to sit centered on the marked zone; a pan pushed to one side, or one noticeably smaller than the zone's minimum diameter, can fail to register the same way a nonmagnetic pan would.

A control lock, active on many Bertazzoni induction cooktops to prevent accidental changes, can also make the surface appear unresponsive. Check for a lock icon before assuming a hardware fault.

Cookware compatibility explains the great majority of "won't heat" complaints on induction. If a properly sized, magnetic pan still fails to register on every zone, that is the point to arrange a diagnosis rather than keep testing pans.
