8406-135 OBSOLETE
- Low Pressure Switch 14 PSIG
Bard part 8406-135 is an OEM low pressure switch with a 14 PSIG setpoint that helps protect the refrigeration circuit by opening the safety control when suction pressure drops too low, which can occur during loss of charge, restricted airflow, or icing conditions. On Bard wall mount air conditioners and related packaged equipment, this switch is used to prevent compressor damage and nuisance operation by forcing the unit to shut down and alert the service technician to correct the root cause. Replace a failed or intermittent switch with the correct Bard OEM part to maintain proper safety interlock operation and ensure dependable system performance; always confirm the setpoint, wiring connections, and model compatibility before installation.
