• Defrost System Replacement Kit

Bard 8620-043 is an OEM defrost system replacement kit used on Bard heat pump wall mount HVAC equipment to restore proper defrost operation when the outdoor coil ices up in cold, damp conditions. A healthy defrost system helps the unit clear frost efficiently, maintain airflow through the outdoor coil, and prevent nuisance lockouts or poor heating performance. This kit is intended as a complete service solution for common defrost-related failures, but exact contents and wiring connections can vary by unit series, so match the part number to your Bard model and serial and follow the unit service literature during installation.
