What the AI looks for in Air Conditioner Replacement Fans
- Part type
- Identify the part first: an axial condenser fan blade, an indoor blower wheel (squirrel cage) or a window-unit slinger fan These parts are not interchangeable, even when they fit on the same motor.
- Diameter and bore
- Match the blade diameter and the hub bore (commonly 1/2 in or 5/8 in), including any D-flat on the shaft A wrong bore wobbles or will not mount at all.
- Rotation and pitch
- Match the rotation direction (CW or CCW, from the stated viewing side), the blade count and the pitch in degrees Wrong pitch or rotation cuts airflow and overloads the motor.
- Blower wheel dimensions
- For blower wheels, match the diameter, width, bore and rotation Wheel width sets the airflow and has to match the housing.
