8406-055 OBSOLETE
- Auto Reset High Press. Switch 450PSI
Bard 8406-055 is an OEM auto-reset high pressure switch used to protect the refrigeration circuit on Bard HVAC equipment by opening the safety/control circuit if head pressure rises to an unsafe level (450 PSI rating), helping prevent compressor damage and nuisance failures during restricted airflow, dirty coils, or condenser fan issues. In Bard parts literature, this component is listed as a high pressure switch for applicable Bard units, and it is intended to restore operation automatically once system pressure returns to an acceptable range, so it is important to diagnose the root cause of the high-pressure condition rather than simply replacing the switch. Confirm fit by matching the part number 8406-055 to your unit model and serial before ordering.
