How it shows up ## What people describe when they call - “Zone beeps and shuts off with a pan on it” - “Some pans work and others do not” - “A wireless probe reporting instead of the cooktop” Two shortcuts ## Narrow it down before anybody arrives A description of the behaviour leaves a few possible causes. A code names the subsystem, and the model number says which parts to bring. Either one shortens the visit; both together usually settle it.

[ All models ](https://thermadormiami.support/models/) In more detail ## About Thermador induction will not recognize the pan ### The magnet test comes first, and it is free Induction heats ferrous metal only. Put a fridge magnet on the base of the pan: if it does not stick firmly, that pan will never work on this cooktop, whatever the appliance does. Copper, aluminum and most glass and ceramic simply cannot be used. ### Two seconds with a magnet Induction generates a magnetic field that induces a current in the base of the pan; the pan is what gets hot, not the glass. Only ferrous metal responds. A magnet that sticks firmly to the base means the pan will work; a magnet that slides off means it will not, and no setting, cleaning or repair changes that. ### When it is the appliance One zone that fails a pan every other zone accepts. That is the coil or its electronics, and it is a real repair — but it is worth arriving at by elimination, because the same complaint from a copper skillet costs nothing to answer. This article is based on: - Official manufacturer documentation - Internal repair procedures - Technician repair history - Company quality standards Before you book ## Questions about thermador induction will not recognize the pan They cannot. Induction works by inducing a current in ferrous metal, and copper and aluminum do not respond. It is the one genuine compromise of induction cooking and it is not something an appliance can be adjusted to overcome. Look at its base. Warping from years of heat is common and it breaks the contact induction depends on. Test it on another zone before assuming the cooktop. The cooking sensor is a separate device with its own battery and its own published conditions. It is a replacement probe rather than a cooktop repair, which is a much smaller thing.
