Wolf Range Error Code 01-00

Error code 01-00 means the oven control has detected an open circuit in the RTD temperature sensor on the left or right oven cavity. The RTD is a resistance-based temperature sensor, and an open circuit means the control board is receiving no valid signal from it. The fault can be caused by a failed sensor element or a break or disconnection in the wiring between the sensor and the control board. The oven will not operate normally until the fault is resolved.

No, it is not safe to operate the oven while this error is present. Because the temperature sensor circuit is open, the control board cannot monitor or regulate oven temperature accurately. This creates a risk of uncontrolled overheating. Discontinue use of the affected oven cavity until the RTD sensor and wiring have been inspected and repaired.

Repair costs depend on what has failed. An RTD sensor replacement part typically ranges from around 30 to 100 dollars or more depending on the specific model, with additional labor costs if a technician performs the repair. If the wiring harness is damaged, parts and labor costs will be higher. Control board replacement, which is only needed in rare cases, is the most expensive outcome and can range from several hundred dollars upward including parts and labor.

A knowledgeable DIYer can perform basic checks such as inspecting connectors and visible wiring for damage, but fully diagnosing this fault requires a multimeter to measure RTD resistance and continuity along the harness. If the RTD sensor element has failed, replacing it involves accessing the oven cavity and working with electrical components. If you are not comfortable working with oven wiring and components, a qualified appliance technician should handle the repair.

Resetting the range by cycling power may temporarily clear the displayed error, but the code will return if the underlying fault in the RTD sensor or wiring has not been corrected. A reset does not repair a failed sensor element or a broken wire. The error will reappear as soon as the control board attempts to read the RTD signal again.
