Bard part number 8105-059-0140BX is a factory programmed service replacement motor used in select Bard wall-mount air conditioners and heat pumps where the motor operating profile is matched to the unit controls for proper airflow and safe, reliable operation. Because this is an OEM programmed motor, it is intended to restore the correct start, run, and speed behavior the equipment was designed around, which helps protect components like the compressor and coils and prevents nuisance trips caused by incorrect aftermarket substitutions. Confirm compatibility by matching the full part number to the unit model and serial number or the Bard parts list before ordering, since programmed motors are not universally interchangeable across platforms.
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.
