Thermador Cooktop Error Code W2

The W2 code indicates that the inductor inside the cooktop has overheated and the appliance has automatically shut off to protect itself. This is a thermal protection response triggered when internal temperatures exceed safe operating limits. It is most commonly caused by an installation issue that restricts airflow or by a problem with the internal cooling fan. The cooktop should resume normal operation once it has cooled down sufficiently.

No. When W2 is active, the cooktop has already shut itself off as a safety measure. You should allow the unit to cool completely before attempting to use it again. Continuing to force the appliance into operation before it has cooled could cause damage to the inductor or power electronics.

If the fix is simply adjusting installation clearances or clearing blocked vents, there may be no parts cost involved, though a service call to diagnose the issue typically runs between 80 and 150 dollars. Replacing an internal cooling fan generally costs between 150 and 350 dollars including parts and labor. If the inductor coil or power board has been damaged by repeated overheating, repair costs can range from 300 to 600 dollars or more depending on the components involved.

The W2 warning is designed to clear automatically once the cooktop cools down to a safe operating temperature. You do not need to perform a manual reset. However, if the error returns every time you use the cooktop, that indicates an underlying problem with installation clearances or the cooling fan that needs to be addressed.

Start by letting the cooktop cool completely and checking whether the warning clears on its own. Next, inspect the installation to confirm that all required clearances around the unit are met and that no ventilation slots are blocked. Listen for the internal cooling fan when the cooktop is powered on. If the fan is silent or the error persists after addressing clearance issues, a technician should inspect the fan motor and inductor assembly.
