The Bard 8106-073-0075BX Programmed Motor - Service is a genuine Bard OEM replacement motor used in select Bard wall-mount HVAC equipment where the motor must be matched to the correct programmed performance profile for proper airflow and system operation. When a motor fails, the unit can suffer from poor air delivery, nuisance trips, or uneven comfort, so replacing it with the correct programmed service motor helps restore the designed starting characteristics, speed control behavior, and overall reliability. Confirm the exact unit model and serial number, along with the motor and control board compatibility, before ordering to ensure the replacement matches the original application and wiring connections.
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.
