Bard 8406-104 - Auto Reset Low Pressure Switch

Bard part 8406-104 is an OEM auto reset low pressure switch used to protect Bard wall mounted air conditioners and heat pumps by monitoring the refrigerant suction pressure. When system pressure drops below the switch setpoint due to issues like low charge, airflow problems, or a restriction, this safety control opens to help prevent compressor damage, then automatically returns the circuit to normal operation once pressure recovers. It is a direct replacement control intended to restore proper low pressure protection and dependable unit operation, and matching the correct Bard part number is critical since pressure switch ratings and connection styles can vary by model and vintage.
