Answer to continue safely
Is it safe to keep using?
No. An over-temperature condition is a fire hazard, especially in built-in installations. Do not use the oven until a technician identifies and repairs the cause.
Can I reset the code?
Yes. A power cycle clears the error, but the underlying fault will cause the oven to overheat again.
When to stop immediately?
Stop if you notice: Oven temperature exceeds setting by 50°F or more, Cabinet surround feels hot to the touch.
Symptoms You May Notice

Possible Causes
Stuck bake or broil relay
A relay on the control board has welded closed, keeping the heating element powered beyond the set temperature.
