Thermador Cooktop Error Code E0245

E0245 means the power board has detected an error while checking the heat sink temperature sensor on the induction module. The power board continuously monitors this sensor to prevent overheating of the induction electronics. When it cannot read a valid signal from the sensor, it triggers E0245 and disables the cooktop. Resolving the error requires inspecting the sensor wiring and, most likely, replacing the power board.

No. The E0245 error is a protective shutdown triggered because the cooktop cannot monitor the temperature of its internal electronics. Operating the cooktop without a functioning heat sink temperature sensor creates a risk of the induction components overheating without warning. The cooktop should remain off until the fault is diagnosed and repaired.

Repair costs vary depending on which component has failed and local labor rates. A power board replacement, which is the primary recommended fix, typically ranges from a few hundred dollars to over five hundred dollars when accounting for parts and labor. If the heat sink temperature sensor or wiring harness is also involved, costs may be lower or comparable depending on parts availability. Getting a diagnostic estimate from a certified Thermador technician before authorizing repair is advisable.

Some preliminary checks, such as inspecting and reseating wiring connectors near the heat sink sensor, can be performed by a technically confident DIYer after disconnecting power to the unit. However, replacing the power board inside an induction cooktop involves working with high-voltage components and requires proper tools and safety precautions. Most homeowners should have a qualified appliance technician handle the repair.

A power reset may temporarily clear the E0245 code, but if the underlying hardware fault remains, the error will return during the next startup or operation cycle. The power board performs a self-check of the heat sink sensor circuit each time the cooktop is powered on, so a persistent hardware fault will trigger the code again. A reset alone is not a repair.
