Lennox 77W93 Actuator
The Lennox 77W93 Damper Actuator is a high-performance direct-coupled actuator engineered for precise airflow control in commercial and residential HVAC zoning systems. Designed for reliability in demand-heavy environments, this unit provides 35 in-lb of torque and a 90-degree rotation, ensuring consistent damper positioning. This modulating actuator operates on a 24VAC/DC power supply and utilizes a 0-10VDC control signal, making it a critical component for technicians maintaining Lennox Harmony zoning systems or other high-efficiency multi-zone configurations.
As a genuine HVAC replacement part (Manufacturer Part Number 102691-04), the Lennox 77W93 offers a seamless fit for specific rooftop units and air handlers, including LGH and KCA models. Its brushless DC motor technology provides smooth operation and prevents stall-related failures, even at its terminal 90-degree limits. For contractors, this means a straightforward drop-in installation that restores system-side efficiency and maintains precise temperature gradients across independent zones without the need for complex field retrofitting.
Key Benefits:- Precise Modulation: Responds accurately to 0-10VDC signals for exact damper positioning and optimized CFM.
- Universal Power Compatibility: Supports both 24VAC and 24VDC inputs to match diverse control transformer outputs.
- Durable Construction: Rated for 35 in-lb of torque to handle standard residential and light commercial damper blades.
- OEM Integration: Specifically designed to replace the 102691-04 motor in Lennox-branded zoning assemblies.
- Reliable Performance: Engineered for quiet operation and long-term cycling in high-demand HVAC systems.
What systems are compatible with the Lennox 77W93 actuator?
This actuator is commonly used in Lennox Harmony III zoning systems and compatible commercial units like the LGH092 and KCA102 series air handlers.
Can I use this to replace a floating control actuator?
No, the 77W93 is a modulating 0-10VDC actuator. Always verify the control signal of your existing logic board before installation.
How do I set the rotation limits?
The unit is fixed for 90-degree rotation, which is standard for most damper blade assemblies used in Lennox zoning packages.
