Utica-Dunkirk 240005933 Motor

The Utica-Dunkirk 240005933 Vent Damper Motor is a critical 24 VAC replacement component designed to regulate exhaust flow in gas-fired furnaces and boilers. As a direct replacement for 510-512-337, this unit features a durable plastic base construction, providing a reliable alternative to older metal-based designs. Operating at 60 Hz with an 80 mA current rating, this low voltage damper motor ensures precise synchronization with system signals to maintain safe combustion environments and optimize thermal efficiency. For technicians servicing Utica or Dunkirk hydronic systems, this OEM replacement part offers seamless integration into existing venting assemblies, preventing energy loss during off-cycles by sealing the flue effectively. Utilizing this furnace vent damper actuator reduces standby heat loss, ensuring equipment meets rigorous performance standards in both residential and commercial applications. When replacing antiquated 510-512-337 dampers, this updated motor provides the necessary torque and timing for reliable shutter modulation.

• Direct Cross-Reference: Engineered to replace obsolete metal-base 510-512-337 units without requiring complex modifications.
• Energy Efficiency: Minimizes standby heat loss by closing the flue when the burner is off, improving overall AFUE ratings.
• Rugged Construction: The high-impact plastic base resists corrosion and environmental wear in demanding mechanical rooms.
• Plug-and-Play Integration: Standardized 24V wiring allows for rapid field installation and reduced downtime for contractors.

Is the 240005933 compatible with older metal-base dampers?
Yes, this motor is the official successor to the 510-512-337. While the base material has transitioned from metal to plastic, the mounting patterns and electrical requirements remain compatible with the specified series.

How do I verify if this vent damper motor is failing?
Typically, a failing actuator will prevent the boiler from firing if the end switch does not prove the damper is in the fully open position. Check for 24 VAC at the motor and ensure the linkage is not obstructed.

Does this motor include the damper blade or just the actuator?
The 240005933 is the motor and cover assembly. It is designed to mount onto your existing vent pipe damper housing and drive the internal shaft.
