Bard S553-539-4 - ERV vent option door assembly
Bard part number S553-539-4 is an OEM ERV vent option door assembly used on select Bard wall-mount HVAC units equipped for energy recovery ventilation. This door assembly closes and seals the ERV vent opening when required, helping the unit maintain correct outdoor air control and cabinet airflow paths so the ERV option can operate as designed. If your existing door is damaged, warped, or not sealing, replacing it with the correct Bard factory part helps prevent air bypass and keeps ventilation performance consistent; confirm compatibility by matching the unit model and serial to the Bard parts manual before ordering.
