Bard 1804-0405 - Low Pressure Switch Assembly
The Bard 1804-0405 low pressure switch assembly is an OEM safety control used on Bard wall-mount air conditioners and heat pump systems to monitor suction pressure and help protect the refrigeration circuit during low charge, airflow problems, or coil freeze conditions. When suction pressure drops below a safe operating range, this switch is designed to interrupt the control circuit to prevent compressor damage and nuisance icing, then allow normal operation to resume once conditions return to acceptable levels. Because pressure switches can vary by cut-in/cut-out settings and wiring style across model families, match Bard 1804-0405 to your unit model and serial information before ordering to ensure proper fit and correct system operation.
