What to do if Winterwarm DXC heat exchange sensor or flue sensor is overheated?
- CChristine BaldwinAug 18, 2025
If the heat exchange sensor or flue sensor is overheating in your Winterwarm Heater, first ensure that connectors J12 and J6 are properly connected and that connection J12[1-4] (optional overheating protection) is closed. Also, check if the system fan is providing sufficient airflow. Finally, verify the gas valve settings, as the heater might be overfired; if so, adjust the burner pressure accordingly.
