Bard 542-139 - CRV/Economizer Fill Plate

Bard part number 542-139 is an OEM fill plate used with CRV and economizer related assemblies to close off openings and restore proper internal airflow separation on compatible Bard wall-mount HVAC equipment. When these plates are missing, damaged, or left loose after service, the unit can pull in bypass air and create performance and control issues, especially around ventilation and free cooling functions. Replacing the 542-139 fill plate helps maintain the intended air path so the economizer or CRV section operates as designed, while keeping the cabinet interior properly sealed for reliable operation. Verify fit by matching your unit model and the applicable Bard parts breakdown before ordering.
