What to do if my Greenheck DFD-210 Fire and Smoke Dampers do not fully open or close?
- A
  Austin DavisAug 7, 2025
  If your Greenheck Fire and Smoke Dampers aren't fully opening or closing, several issues could be the cause. First, the frame may be ‘racked,’ causing the blades to bind. In this case, adjust the frame to be square and plumb. Another potential cause is a loose actuator linkage; if so, close the damper, disconnect the power, and then adjust and tighten the linkage. A defective motor could also be the culprit, requiring replacement. Screws in the damper linkage should be located and removed. If the actuator linkage is hitting a wall or floor, the damper is installed too far into the wall and needs to be moved out to the designated line on the damper label. Finally, contaminants on the damper can impede movement; clean them off using a non-oil-based solvent.

  If your Greenheck Fire and Smoke Damper doesn't fully open or close, several factors could be at play. First, the frame might be 'racked,' causing the blades to bind. In this case, adjust the frame to ensure it's square and plumb. Another potential cause is a loose actuator linkage; to resolve this, close the damper, disconnect the power, and then adjust and tighten the linkage. A defective motor could also be the culprit, requiring replacement. If screws are present in the damper linkage, it may be installed too far into the wall; move it out to the designated line on the damper label. Finally, contaminants on the damper can impede its function; clean it with a non-oil-based solvent.
