Wolf Oven Error Code 5122

Error code 5122 means the lower oven reached an excessively high temperature during a normal cooking mode, not during a self-clean cycle. The oven's control system detected the temperature exceeded safe operating limits and shut down to prevent damage or a safety hazard. The fault points to a problem with the temperature sensor, control board relay, or heating element. A technician should diagnose the root cause before the oven is used again.

Resetting the oven by cycling power may clear the code temporarily, but it will not fix the underlying problem causing the overheating. If the fault condition still exists, the code will return, often quickly. A reset should only be used as part of diagnostics, not as a repair strategy.

Repair costs vary depending on which component has failed. A temperature sensor replacement typically falls in a lower range, while control board replacement is a more significant expense due to part cost and labor. For a Wolf appliance, you can generally expect to budget anywhere from $150 to $600 or more depending on the diagnosis, parts required, and your local labor rates.

No, you should not use the oven until the fault has been diagnosed and repaired. An uncontrolled high-temperature condition can damage internal components, surrounding cabinetry, and poses a fire risk. The oven shut down as a protective measure, and that protection will not be reliable again until the underlying cause is corrected.

Start by verifying the actual lower oven temperature with an independent thermometer to confirm the overheat condition is real. Then check the temperature sensor resistance and inspect wiring connections at the sensor and control board. If the sensor and wiring are sound, the control board relays or the board itself are the likely culprits and will need professional evaluation and replacement.
