Bard 1804-0386BX - Low pressure switch assembly
The Bard 1804-0386BX low pressure switch assembly is an OEM safety control used on Bard wall mounted air conditioners and heat pump systems to monitor suction pressure and help protect the compressor during low charge, airflow problems, or coil freeze up conditions. This switch is commonly listed as a 40 psi cut out with a 55 psi cut in setting, so it can shut the unit down when refrigerant pressure drops too low and allow operation to resume after pressure recovers. If you are troubleshooting nuisance lockouts, suspected loss of charge, or a pressure switch that will not reset, replacing with the correct Bard 1804-0386BX ensures proper fit, correct factory settings, and reliable system protection.

What does the "BX" suffix mean?
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
