Wolf Range Error Code 2931

Error code 2931 means the incoming voltage level detection circuit on the relay board for the right oven is malfunctioning. The range detected that this circuit is not operating correctly and has flagged the fault to prevent potential damage to the oven's components. The issue can originate from the relay board itself, its wiring connections, or the incoming power supply.

It is not recommended to continue using the right oven while this fault is active. The error indicates the control system cannot properly monitor the incoming voltage, which means the oven may not operate correctly or safely. Discontinue use of the right oven and have the range inspected by a qualified technician before resuming operation.

The most likely part requiring replacement is the right oven relay board, which houses the voltage level detection circuit that has malfunctioned. Before replacing the board, a technician should verify the incoming power supply is within specification and that all wiring harness connections to the board are secure and undamaged. In some cases, only a wiring repair is needed rather than a full board replacement.

You can attempt to reset the range by powering it off at the circuit breaker for several minutes and then restoring power. However, if the underlying cause, whether a faulty relay board, wiring issue, or power supply problem, has not been corrected, the error code will return. A reset alone is not a fix for this fault.

Repair costs will depend on the root cause identified during diagnosis. If the fix involves tightening or replacing wiring connections, costs may be relatively low, typically in the range of $100 to $250 for a service call and labor. If the relay board requires replacement, parts and labor combined can range from $300 to $700 or more, depending on the specific board and local labor rates.
