Wolf Range Error Code 0122

Error code 0122 means the control system has detected that the right convection element drive relay or triac in the left oven is closed when it should be open. This indicates the heating circuit is stuck in an energized state, which can cause uncontrolled heating. The primary corrective action is to replace the oven relay board.

No, it is not safe to continue using the oven with this error active. Error 0122 indicates a component is stuck in the on position, which means the heating element may energize without a command, creating a risk of overheating or fire. The oven should remain off and unplugged or disconnected at the breaker until the relay board has been replaced and the fault is cleared.

A power reset will typically clear the displayed error code temporarily, but it will not resolve the underlying hardware fault causing code 0122. If the relay contacts are welded or the triac is shorted, the fault condition will persist and the code will return when the oven is operated again. The relay board must be replaced to permanently resolve this error.

Replacing the oven relay board is a repair that requires disconnecting the appliance from power and working with high-voltage components, so it is best performed by a qualified technician. A knowledgeable DIYer with experience in appliance repair may be able to complete the board replacement, but the internal wiring, connectors, and board location should be confirmed against the specific model before attempting any work. Always disconnect power completely before beginning any disassembly.

The cost to repair this error typically depends on the price of the relay board and labor rates in your area. Parts costs for Wolf relay boards generally fall in the range of $150 to $400 depending on the specific model, and professional labor can add $100 to $250 or more.
