Bard part 8107-029-0180BX is an OEM programmed blower motor service replacement used in select Bard wall mounted HVAC units to restore proper indoor airflow and stable system operation when a motor is noisy, overheating, or failing to start. Because this is a programmed motor, it is intended to match the specific performance profile required by the unit so the blower can run at the correct speeds for heating, cooling, and ventilation calls, helping protect coils and prevent nuisance trips. Confirm compatibility by matching the full part number to your Bard model and serial, and replace the motor using standard HVAC safety procedures including disconnecting power and verifying correct wiring and rotation after installation.
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.
