Thermador Cooktop Error Code E0146

E0146 indicates a pot detection sensor error in the left ADB induction module. The cooktop is unable to correctly detect whether cookware is present on the left cooking zone. This fault is typically caused by wiring issues between the power board and the ADB module, or by a failure of the ADB module itself. The left cooking zone will be disabled until the fault is resolved.

The left cooking zone affected by E0146 will typically be disabled by the control system, which is a built-in protection measure. You may be able to use other zones on the cooktop, but you should not attempt to bypass or ignore this fault. Operating the unit with a compromised pot detection circuit could lead to unpredictable induction coil behavior.

Repair costs vary depending on the failed component and local labor rates. If only wiring or connector work is needed, costs may range from roughly $100 to $250 for a service call and labor. If the left ADB induction module or power board requires replacement, parts and labor combined could range from $300 to $700 or more, depending on part availability and technician rates.

A knowledgeable DIYer can start by checking the wiring harness between the power board and the left ADB module for loose connectors or visible damage. However, if the fault lies within the ADB module or the power board, component replacement is required and working inside an induction cooktop involves high-voltage components that carry serious shock risk. Professional service is strongly recommended for anything beyond basic wiring inspection.

Powering the cooktop off at the circuit breaker for a few minutes and then restoring power may temporarily clear the error code. However, if the underlying wiring fault or component failure is still present, the E0146 code will return once the system runs its diagnostics again. A reset does not repair the root cause.
