Bard 8406-121 - Low Pressure Switch, Auto Reset
Bard part number 8406-121 is an OEM low pressure switch with auto reset that helps protect Bard wall mount and packaged HVAC equipment by opening the safety circuit when suction pressure drops below a safe level, then automatically restoring operation once pressures return to normal. This control is commonly used to prevent compressor damage caused by loss of charge, restricted airflow, freeze-up conditions, or other low suction events. If you are troubleshooting nuisance shutdowns or verifying a refrigeration safety control during service, replacing a worn or out-of-spec switch with the correct Bard 8406-121 helps maintain proper factory safety logic and dependable system operation. Confirm compatibility by matching the part number to your unit model and wiring configuration before ordering.
