Wolf Range Error Code 01-01

Error code 01-01 on a Wolf range indicates a shorted RTD condition on the left or right oven temperature sensor. The control board has detected a resistance reading below the expected range, which signals a short circuit in either the sensor element or the wiring connected to it. The oven will not function normally until the fault is resolved.

It is not advisable to operate the affected oven cavity while the 01-01 fault is active. Because the temperature sensor is shorted, the control board cannot accurately monitor oven temperature, which creates a risk of overheating or uncontrolled cooking conditions. The oven should remain unused until the sensor and wiring are inspected and the fault is corrected.

Resetting the range by cycling power may temporarily clear the displayed fault, but the error will return as soon as the control board performs its sensor check at startup or during operation. A reset does not address the underlying short circuit in the RTD sensor or wiring. The root cause must be diagnosed and repaired to permanently clear the 01-01 code.

A knowledgeable DIYer with a multimeter can perform initial diagnostics by disconnecting the RTD sensor and measuring its resistance at room temperature to determine whether the sensor or the wiring is at fault. However, replacing the RTD probe or repairing oven wiring involves working with internal components and should be approached carefully. If you are not comfortable working on appliance wiring, a qualified technician is recommended for the actual repair.

Repair costs depend on whether the fault lies in the RTD sensor, the wiring harness, or both. RTD sensor replacement parts for Wolf ranges typically fall in the range of $30 to $100 for the component alone. With professional labor, total repair costs can range from $150 to $350 or more depending on your location and the extent of wiring damage found.
