Dunkirk boiler furnace

tricia Member Posts: 3
Our boiler unit goes to E53 every time it is windy. We unplug unit and it restarts. Anyone have this problem or have an idea for solution?


  • Can you tell us the model number of the boiler?—NBC

    You can choose to do what you want, but you cannot choose the consequences.

    The control flashes error 53 and if it gets unplugged from outlet and repluged then the system will run it seems to happen on windy days so I wondered if wind going into exhaust pipe is activating the sensors to shut off??
