Wolf Oven Error Code OVER TEMP

OVER TEMP means the oven cavity reached a critically high temperature that triggered a safety shutoff. The threshold is 630°F with the door unlocked during normal cooking, or 930°F with the door locked during self-clean. The oven shuts down automatically to prevent damage or fire. A failed RTD sensor or a stuck relay on the relay board is typically responsible.

Resetting the oven by cycling power may clear the displayed error temporarily, but it will not fix the underlying cause. If the RTD sensor or relay board has failed, the oven will likely reach the over-temperature threshold again and trigger the fault a second time. A proper diagnosis of the sensor and relay board is required before the oven can operate safely.

Repair costs vary depending on whether the RTD sensor, the relay board, or both need to be replaced. An RTD sensor replacement is generally the less expensive repair, typically ranging from $75 to $200 including parts and labor. Relay board replacement tends to cost more, often in the range of $200 to $500 or higher depending on labor rates in your area. Getting a diagnostic visit from a qualified Wolf service technician will give you an accurate estimate.

No, the oven should not be used until the fault is diagnosed and repaired. The OVER TEMP fault indicates the oven exceeded safe operating temperatures, which means a component controlling heat input may have failed. Continuing to operate it could result in further damage to internal components or create a fire hazard.

The first step is to test the RTD temperature sensor with an ohmmeter to verify it is reading within its correct resistance range. If the sensor is out of spec, replacing it should resolve the fault. If the RTD sensor tests good, the relay board needs to be replaced, as a stuck relay is the most likely cause of uncontrolled heating.
