Field Controls 70009800 Motor Assembly

The Field Controls 70009800 Motor Assembly is a direct 24Vac GVD replacement motor designed for peak performance in residential and commercial venting systems. Engineered as the Model GMA-AL, this unit features a durable metal base that ensures superior heat dissipation and structural integrity during high-cycle operations. As a technician, you know the importance of a reliable automatic vent damper motor for maintaining flue pressure and preventing heat loss. This assembly is specifically built to interface with GVD series dampers, providing the high-torque output necessary to actuate the damper blade reliably against backpressure. The low-voltage 24V motor simplifies installation within existing control circuits, making it an essential service part for restoring safe appliance operation. By utilizing Field Controls replacement parts, you preserve the original equipment manufacturer (OEM) specifications, ensuring the vent damper actuator operates with the precise timing required for modern high-efficiency HVAC systems.

• Metal Base Construction: The GMA-AL model utilizes a robust metal chassis for improved durability compared to plastic alternatives.
• OEM Compatibility: Designed specifically as the drop-in replacement for Field Controls GVD series dampers to ensure seamless electrical and mechanical alignment.
• Efficient Torque Delivery: Optimized gear ratios provide consistent opening and closing forces to prevent damper sticking.
• Simplified Wiring: Standard 24Vac configuration allows for rapid field installation without the need for additional transformers.

Common Questions

Is the 70009800 a direct replacement for plastic-based GVD motors?
Yes, this metal base motor assembly (GMA-AL) is the upgraded technical replacement for older plastic-style GVD motors, offering better heat resistance.

Does this motor assembly include the wiring harness?
This unit is designed to utilize the existing plug-and-play harness found on Field Controls GVD damper assemblies for a streamlined swap-out.

What are the symptoms of a failing vent damper motor?
Common indicators include the damper failing to open during the call for heat, leading to an appliance lockout, or audible grinding during the actuation cycle.
