Thermador Cooktop Error Code E10

The E10 error code on a Thermador induction cooktop indicates that the NTC (Negative Temperature Coefficient) thermistor is reporting an incorrect temperature reading from the inductor zone. NTC sensors are resistive temperature devices embedded near or on the induction coils; they change resistance in a predictable way as temperature rises, allowing the control system to monitor heat levels and prevent overheating. When the system detects a temperature value that falls outside expected parameters, it flags the E10 fault to protect the cooktop from thermal damage.

The two most likely root causes are crosswise NTC wiring connections or a defective ADB (Actuator Driver Board). Crosswise connections occur when NTC sensor wires from adjacent inductors are swapped or misrouted during assembly or after a previous repair. This causes the control system to read the wrong zone's temperature, resulting in mismatched or implausible sensor data. Because multiple induction zones share a wiring harness routed through the same area, it is straightforward for connections to be inadvertently transposed.

If the NTC wiring is confirmed to be correctly routed and seated, the fault points to the ADB itself. The ADB interprets the NTC resistance signals and translates them for the main control board. A failed or damaged ADB can produce erroneous temperature readings even when the sensor and wiring are functioning properly. Diagnosis requires systematically checking each NTC connection in the affected zone before concluding that board replacement is necessary.
