Thermador Cooktop Error Code E0145

E0145 indicates that the left ADB (Auxiliary Driver Board) has detected a fault in the induction module's temperature sensor circuit during its self-check routine. The ADB is identified as the faulty component. This error will typically disable the left cooking zone as a protective measure until the fault is resolved.

The affected left cooking zone should be considered non-operational and should not be used while this error is active. The cooktop's protective system has flagged that zone due to a temperature monitoring failure, meaning overheating could go undetected. Other zones on the cooktop may still function normally, but use caution and address the fault promptly.

Repair costs vary depending on parts pricing and local labor rates, but technicians typically charge between 150 and 350 dollars for labor on a cooktop board replacement. The left ADB (relay board) itself can range from 100 to 300 dollars depending on the specific model. Total repair costs generally fall in the range of 250 to 650 dollars, which may influence whether repair or replacement is the better option for older units.

The repair requires replacing the left relay board (ADB), which involves disassembling the cooktop and working near high-voltage components. This job is best handled by a qualified appliance technician. Knowledgeable DIYers comfortable with appliance electronics can attempt it, but safety precautions including disconnecting power at the breaker are essential before any disassembly.

A power reset by switching off the circuit breaker for 30 to 60 seconds may temporarily clear the error, but it is very likely to return because the underlying hardware fault on the ADB persists. A reset does not repair a failed board or damaged wiring. The error will reappear as soon as the ADB runs its self-check routine again.
