Thermador Range Error Code 10

Error code 10 indicates that the NTC temperature sensor has failed in a shorted condition. The control board detected abnormally low resistance from the sensor, which prevents it from accurately reading temperature. The appliance will not operate normally until the fault is resolved. Testing the sensor resistance and replacing it if it falls outside the 5.4 to 6.5 k-ohm range at room temperature is the correct first step.

It is not advisable to operate the appliance while error code 10 is active. The control board cannot accurately monitor temperature without a functioning NTC sensor, which means it cannot regulate heating properly or protect against overheating conditions. Continuing to use the range in this state could pose a safety risk or cause additional component damage.

A power reset by disconnecting the appliance from power for several minutes may temporarily clear the error code from the display, but it will not resolve the underlying hardware fault. If the NTC thermistor is genuinely shorted, the code will return as soon as the control board performs its sensor check at the next startup. Permanent resolution requires testing and replacing the faulty component.

A knowledgeable DIYer comfortable with a multimeter can perform the resistance test on the NTC sensor by disconnecting it from the wiring harness and measuring across its terminals. If the reading is outside the 5.4 to 6.5 k-ohm range at approximately 20 degrees C (68 degrees F), replacing the sensor is straightforward. However, if the sensor tests correctly and the fault points to the wiring harness or control board, professional diagnosis is recommended.

If the NTC thermistor itself is the failed component, parts and labor costs are typically in the range of $100 to $250 depending on the technician's rates and part availability. If the fault turns out to involve the control board, repair costs can rise considerably, often falling in the $300 to $600 range or higher. Getting a diagnostic visit from a certified technician first will clarify which component needs replacement.
