Wolf Oven Error Code 1122

Error code 1122 on a Wolf oven indicates an open circuit condition detected in the right convection element drive circuit on the lower oven relay board. The relay board controls power delivery to the convection heating elements by switching relays that complete the circuit between line voltage and the element terminals. When the board's internal monitoring detects that the drive circuit for the right convection element is open, meaning the circuit is broken and no current can flow, it triggers this fault code and typically disables the affected heating function.

An open drive circuit can result from a failed relay on the board itself, a burned or broken trace on the relay board's PCB, or a fault within the board's control circuitry that governs the right convection element relay. Because the fault is specifically identified as originating in the drive circuit on the relay board rather than the element wiring or the element itself, the diagnostic process centers on the relay board as the primary suspect. Physical damage, heat stress from repeated cycling, or component fatigue over time are common contributors to this type of relay board failure.

The first and primary diagnostic step recommended for this fault is replacement of the lower oven relay board. This is consistent with the nature of the fault, since the open condition is attributed directly to the board's drive circuitry. Before replacing the board, a technician may visually inspect the board for signs of burning, cracked solder joints, or failed relay components, but in most cases the board must be replaced to restore proper operation of the right convection element.
