Lennox 78G10 Motor

The Lennox 78G10 24V Damper Motor is a critical OEM component engineered for high-precision airflow management within residential and commercial zoning systems. Also identified by part numbers 78G1001 and DM-2, this 24V damper actuator is designed for direct integration into Lennox-branded HVAC equipment. Its primary function is the automated actuation of HVAC dampers, allowing for specialized temperature regulation in individual zones. By utilizing a low-voltage 24VAC power supply, the unit provides a reliable, high-torque solution for maintaining static pressure balance and optimizing overall system performance. For technicians servicing legacy or modern Lennox HVAC systems, the 78G10 ensures seamless mechanical compatibility and electrical synchronization with existing control boards.

• OEM Compatibility: Exact replacement for Lennox 78G10, 78G1001, and DM-2 units, ensuring no-drill installation and perfect alignment.
• Precision Airflow Control: Facilitates accurate damper positioning to resolve hot and cold spots throughout the building.
• Enhanced Efficiency: Reduces unnecessary blower load and energy consumption by effectively sealing or opening zones as required by the zoning controller.
• Durable Construction: Built with high-grade internal gearing to withstand the frequent cycling common in high-demand HVAC applications.

Is the Lennox 78G10 interchangeable with the DM-2?
Yes, the 78G10 is the direct 24V equivalent and is functionally identical to the YR DM-2 and 78G1001 part numbers.

What are the power requirements for this damper motor?
This motor operates on a standard 24VAC power supply, making it compatible with most residential and light commercial control transformers.

Can this motor be used on non-Lennox dampers?
While specifically designed for Lennox zoning dampers, compatibility depends on the shaft size and mounting bracket configuration. Always verify mechanical specs before attempting installation on third-party hardware.
