Thermador Cooktop Error Code E013D

E013D means the cooktop's self-diagnostic routine has detected a fault in the relay activation circuit of the left ADB, which is the Activator Driver Board controlling the left induction zone. The board is responsible for triggering the relay that supplies power to the left burner. When this circuit fails its check, the cooktop logs E013D and disables that zone. The ADB itself is identified as the faulty component.

The left induction zone affected by E013D should be considered non-operational and should not be relied upon while the fault is active. The cooktop disables the faulted zone as a protective measure. Other zones may continue to function, but it is best to have the fault resolved before using the unit extensively to avoid further component damage.

Repair costs depend on parts pricing and labor rates in your area. The left ADB replacement part itself typically falls in the range of $150 to $400 depending on the specific cooktop model. Adding professional labor, total repair costs generally range from $250 to $600 or more. Getting a quote from an authorized service provider before proceeding is recommended.

Replacing the left ADB is a component-level repair that involves accessing internal cooktop electronics, which carries risk of electric shock if not done with the unit fully disconnected from power. Technicians with experience in induction cooktop servicing are best suited for this repair. A knowledgeable DIYer comfortable with appliance electronics can perform it, but safety precautions around high-voltage capacitors in induction systems must be followed carefully.

A power reset may temporarily clear the error display, but because E013D reflects a hardware fault within the ADB relay activation circuit, the code will return once the cooktop runs its self-diagnostic again. A reset does not repair the underlying board-level failure. Permanent resolution requires replacing the left ADB.
