Flap motor De Dietrich 7812380

A flap motor is an actuator used in heating systems to control dampers or flaps that regulate airflow or exhaust. In boilers and burners, it adjusts the position of flue gas dampers or air intake flaps for optimal combustion. When the flap motor fails, it can cause improper air mixture or safety issues. Replacing it with a compatible motor restores precise control and is a common part in boiler and burner maintenance.
