Bard part number 8106-072-0154BX is an OEM programmed motor service replacement used in select Bard wall-mount HVAC units to restore proper fan and airflow operation when a motor fails, becomes noisy, or will not ramp correctly under load. Because this is a programmed motor, matching the exact part number is important for correct speed control and system performance with the existing Bard controls. If you are troubleshooting intermittent airflow, nuisance safeties, or poor temperature control tied to the indoor fan, replacing the motor with the correct Bard OEM 8106-072-0154BX helps bring the unit back to factory-intended operation and reliability.
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.
