Flame Sensor Circuit Failure
The flame sensor is not detecting a flame after the gas valve opens, causing the system to shut down the burner.
What This Error Code Means
The control board isn't receiving a flame signal, so it closes the gas valve as a safety precaution.
Common Causes
- Dirty flame sensor rod
- Flame sensor wire damaged or disconnected
