Fasco D189 Motor

The Fasco D189 is a high-performance 3.3-inch diameter motor designed for reliable intermittent or continuous duty in HVAC applications. This 1/20 HP shaded pole motor operates at 208-230V and 60Hz, delivering a consistent 1500 RPM with a Counter-Clockwise (CCW) rotation. Built with a 3-3/8 inch frame size and an Open Air Over (OAO) enclosure, it provides efficient heat dissipation for standard condenser fan motor and blower assemblies. The motor features a 5/16-inch diameter shaft measuring 2-1/4 inches in length and utilizes dependable sleeve bearings for quiet operation. As a direct Fasco 398 replacement, it mounts via a standard 2-5/8 inch thru-bolt pattern, ensuring seamless drop-in installation for field service technicians. Rated for Class B insulation and featuring automatic thermal protection, this unit maintains operational integrity in ambient temperatures up to 40°C.

Common Questions:

What is the standard rotation for the Fasco D189?
This motor is fixed at Counter-Clockwise (CCW) rotation as viewed from the lead end/shaft end. Always verify your existing blower wheel or fan blade pitch before installation.

Can I use this motor to replace a 115V model?
No, this is a dedicated 208-230V motor. Installing this on a 115V circuit will result in insufficient torque and potential motor failure.

Is the D189 compatible with multi-speed systems?
The Fasco D189 is a single-speed motor. If your application require multiple speed taps, you will need to source a multi-speed equivalent with matching physical dimensions.
