Thermador Cooktop Error Code E2332

Error code E2332 on a Thermador cooktop indicates a fault in the inductor temperature sensor, specifically the NTC (Negative Temperature Coefficient) thermistor, on the right ADB (Active Burner Driver) module. The NTC thermistor is a resistive sensor whose resistance decreases predictably as temperature increases. The cooktop's control board continuously monitors this resistance to track the temperature of the induction coil and glass surface in real time. When the control board cannot read a valid signal from this sensor, it triggers E2332 to prevent overheating or unsafe operation.

The fault is typically caused by one of two conditions: the NTC thermistor is physically disconnected from its circuit, or it is not making full, flush contact with the underside of the ceramic glass surface. Proper contact is critical because the sensor relies on direct thermal coupling with the glass to produce accurate readings. If the sensor has shifted out of position, perhaps due to vibration or a prior repair, the resistance value reported to the control board will be out of the expected range, registering as an open circuit or erroneous reading.

The right ADB designation means this fault is isolated to the induction zone controlled by the right burner driver board. Other burner zones may continue to function normally. Diagnosis should begin by confirming the NTC is seated correctly against the glass and that its wiring harness connector is fully engaged. If repositioning the sensor does not resolve the fault, the sensor itself may have failed and will need resistance testing to confirm.
