8406-049 OBSOLETE
- Auto Reset Low Press. Sw.
Bard part number 8406-049 is an OEM auto reset low pressure switch used on Bard wall mounted air conditioners and heat pump packages to protect the refrigeration circuit during a loss of charge, airflow problems, or other conditions that pull suction pressure too low. When pressure drops below the switch setpoint, it opens the safety circuit to stop cooling operation and help prevent compressor damage, then automatically resets once normal pressure returns. If your Bard unit is short cycling on low pressure or showing a low pressure safety fault, replacing the 8406-049 with the correct OEM switch helps restore reliable operation and proper protection, but always confirm the exact part number match using your unit model and serial before ordering.
