8406-129 OBSOLETE
- Low Pressure Swt. Auto Reset
Bard part number 8406-129 is an OEM low pressure switch with automatic reset used on Bard wall mounted HVAC equipment to monitor refrigerant suction pressure and open the control circuit if pressure drops to an unsafe level. In normal operation, this safety helps protect the compressor from running during loss of charge, restricted airflow, or coil freeze conditions, then automatically returns the unit to service once pressure recovers. It is a direct-fit Bard replacement intended to restore proper factory safety operation, so confirm your model and serial number requirements before ordering to match the correct cutout and wiring style.
