GE Oven Error Code Abnormal High Temp

This error means the oven detected that its internal temperature was running higher than the temperature you selected, and that condition persisted for more than 30 minutes during a bake cycle. The oven flags this as a fault to prevent unsafe overheating. It points to a problem with the thermistor assembly, the convection heater thermal cutout, or a stuck relay on the relay board.

Resetting the oven by cutting power at the breaker may temporarily clear the error code, but if the underlying fault is still present the error will return once the oven runs another bake cycle. A stuck relay or failed thermistor will not correct itself after a reset, so a reset alone is not a solution.

Repair costs vary depending on which component has failed. A replacement thermistor assembly typically runs in the range of $20 to $60 for the part. A relay board can cost anywhere from $80 to $200 or more depending on the model. Adding professional labor, total repair costs commonly fall between $150 and $400, though this can vary by region and the specific parts required.

No, you should stop using the oven until the fault is diagnosed and corrected. An oven running significantly hotter than the set temperature for extended periods is a potential fire hazard and can damage internal components. Disconnect power to the unit and have it inspected before resuming use.

Start by checking the thermistor assembly for accurate resistance readings, then inspect the convection heater TCO for proper continuity, and examine the relay board for signs of stuck or damaged relay contacts. If the relay board has a welded relay, it will need to be replaced. A faulty thermistor or failed TCO will also require part replacement.
