• Blower Door Assembly-Gray

Bard 552-331-4 is an OEM blower door assembly used on select Bard wall-mount HVAC units to properly close off the blower section, helping maintain correct airflow through the blower and filter path while also supporting safe, service-friendly access during maintenance. A damaged or missing blower door can lead to air bypass, reduced comfort, nuisance issues, and performance complaints, so replacing it with the correct Bard factory door is a practical fix when you need the unit to seal and operate the way it was designed. Verify the exact match by cross-checking this part number against your unit model and serial data before ordering.
