🛒 Shopping Tips
✔️ Confirm your vent damper is a Field Controls GVD model.
✔️ Check your furnace/boiler uses a 24V vent damper motor.
✔️ Inspect wiring for 105°C thermostat wire before installation.
✔️ Replace the motor assembly at the first sign of sticking or delayed operation.
✔️ If the damper does not fully open/close within 15 seconds, the motor is likely failing.
