Wolf Oven Error Code 1731

Error code 1731 on a Wolf oven means the control board has detected an open circuit in the oven light drive for the upper or single oven cavity. The board is not seeing a completed electrical circuit when it attempts to activate the light. This is often caused by a burned-out bulb, a broken wire, or a failed socket, though a faulty control board is also possible.

Resetting the oven by cycling power may temporarily clear the fault display, but the code will return if the underlying open circuit condition is still present. A lasting fix requires identifying and correcting the root cause, such as replacing the bulb or repairing the wiring. Resetting is useful for confirming whether the fault is intermittent, but it does not resolve the issue.

Repair costs vary depending on what component has failed. A replacement oven light bulb is typically a low-cost fix in the range of a few dollars to around $20. Socket replacement or wiring repairs may run $100 to $300 including labor. Control board replacement, if needed, is the most expensive scenario and can range from $400 to $800 or more depending on the model and labor rates in your area.

In most cases the oven can continue to operate for cooking even with code 1731 active, since the fault is limited to the interior light circuit. However, the error should be addressed to restore normal function and to prevent any underlying wiring issue from worsening. If the error is accompanied by other faults or unusual behavior, stop using the oven and consult a technician.

Begin by replacing the oven light bulb, as this is the most common cause. If the bulb is intact, inspect the light circuit wiring and connectors for any breaks or loose connections, and test the light socket for continuity. If the bulb, wiring, and socket all check out, the control board's light drive circuit may need to be evaluated by a qualified technician.
