The Bard 8408-039BX is an OEM discharge line thermostat (T-stat), boxed for service replacement, used on Bard wall-mounted HVAC equipment to monitor compressor discharge line temperature and open or close its contacts at the specified setpoints (commonly referenced as L250-50F) to help protect the refrigeration circuit from abnormal high-temperature conditions. When a discharge line stat is weak, out of calibration, or intermittently open, it can cause nuisance shutdowns or poor reliability, so replacing it with the correct Bard factory part helps restore proper safety control operation and original wiring and mounting fit. Confirm compatibility by matching your unit model and serial number to the Bard parts list before ordering.
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.
