Wolf Range Error Code 4122

Code 4122 means the Wolf range control system detected no load, meaning no current draw, when it attempted to turn on the right convection element in the left oven cavity. The oven expects to sense the element conducting electricity, and when that does not happen, it logs this fault. The most common cause is a burned-out heating element, though wiring and control board relay failures are also possible.

With error 4122 active, the right convection element in the left oven will not function, so convection baking performance in that cavity will be compromised or completely unavailable. The oven may still operate in bake mode using other elements depending on the model, but you should not ignore the fault. Continuing to use the oven with a damaged element or wiring connection present carries a risk of further electrical damage, and the issue should be diagnosed and repaired promptly.

Repair costs depend on which component has failed. A replacement convection heating element typically runs in the range of $50 to $150 for the part, while control board replacement can cost considerably more, often in the range of $200 to $500 or higher for the part alone. Adding professional labor charges, total repair costs can range from around $150 to $700 or more depending on the specific failure and your location.

A knowledgeable DIYer comfortable working with appliances can perform basic diagnostics such as visually inspecting terminals and testing element resistance with a multimeter after disconnecting power. However, replacing the convection element or the control board involves working inside a high-voltage appliance, and for many homeowners it is safer to have a qualified appliance technician complete the repair. Always disconnect the range from power before inspecting any internal components.

Resetting the oven by cycling the power at the circuit breaker may temporarily clear the displayed code, but the fault will return as soon as the control system attempts to energize the right convection element again and detects no load. The underlying cause, whether a failed element, broken wiring, or bad relay, must be physically repaired before the code will stay cleared.
