Wolf Range Error Code 4731

Code 4731 indicates a fault in the right oven light circuit. The control board detected either no electrical load when it commanded the light on, or the light circuit was conducting when it should have been off. The fault can originate at the bulb, socket, wiring harness, or the control board itself.

The error is specific to the oven light circuit and does not directly affect the heating elements or cooking function. However, using any appliance with an unresolved electrical fault carries some risk. It is advisable to have the fault diagnosed promptly, especially if the control board is found to be conducting the light circuit at unintended times.

Repair costs vary depending on the root cause. Replacing the oven light bulb is inexpensive, typically in the range of a few dollars to around $20 for the part. Socket or harness repairs may cost more depending on labor. If the control board requires replacement, parts and labor combined can range from several hundred to over a thousand dollars for a premium appliance like a Wolf range.

In some cases, yes. Start by checking whether the right oven light bulb has burned out and replacing it if needed. You can also visually inspect the socket and the wiring harness for obvious damage or loose connections. If those steps do not resolve the fault, diagnosing the control board drive circuit requires electrical testing skills and is best handled by a qualified appliance technician.

A power reset may temporarily clear the error code from the display, but if the underlying fault in the light bulb, socket, or wiring is still present, the code will return when the oven light circuit is activated again. A reset alone is not a repair and should not be relied on as a solution.
