What's Happening
The oven temperature sensor has an open circuit — the sensor or its wiring is disconnected or broken. The oven will not heat with this error active.
How to Fix It
Power off at the breaker. Check the sensor probe connection at the back of the oven cavity — it may have come loose. If connections are secure, the sensor itself has failed. Test with a multimeter — if it reads infinite resistance (open), replace the sensor.
