• Simplified Installation: Features a standardized 24VAC motor connector for rapid field service and reduced equipment downtime.
• Enhanced Thermal Durability: The high-grade plastic base construction provides high-heat resistance and electrical insulation in demanding flue applications.
• Optimized Energy Efficiency: Restores precise automatic vent damper control, preventing heated air from escaping through the chimney.

Common Questions

How do I know if I need a GVD replacement motor?
If the thermostat calls for heat but the burner fails to ignite, and your diagnostic reveals the damper is stuck in the closed position while receiving 24VAC, the 46491600 motor assembly is the likely culprit.

Is the GMA-PL motor compatible with metal-base GVD units?
Yes, the Field Controls 46491600 with the plastic base (GMA-PL) is the current standard replacement for older GVD models, provided the wiring harness matches the 24V configuration.

Can I replace the motor without removing the damper pipe?
Absolutely. This assembly is designed for external mounting, allowing for a plug-and-play installation that doesn't require breaking the flue connection.
