Bard part 8406-096 is an OEM low pressure switch with auto reset used on Bard HVAC equipment to help protect the refrigeration circuit when suction pressure drops below a safe operating range. In normal operation, this safety switch can open the control circuit during a loss-of-charge, airflow, or coil-freeze condition, then automatically reclose once pressure returns to acceptable levels, helping the unit recover without a manual reset. For best results, confirm the part number match to your specific Bard model and serial number, and inspect the refrigerant charge and airflow issues that may have caused the low pressure trip before returning the system to service.
* Orders less than $50 may incure a minimum order fee.
