Reznor 55680 Motor

The Reznor 55680 Blower Motor is a critical OEM replacement part engineered for high-static applications in Reznor unit heaters and ventilation systems. This 115V single-phase motor delivers 1/20 HP at a rated speed of 1050 RPM, ensuring precise airflow for optimal heat exchange. Designed with a type FE frame and a 7/16" x 2 1/2" D-shaft, it provides a direct mechanical fit for legacy and current Reznor configurations. This forced-air furnace motor operates at 3.0 Amps and 60Hz, featuring a 9-inch cord for straightforward integration into existing wiring harnesses. As a genuine Reznor part, it eliminates the performance inconsistencies often found with universal aftermarket motors, maintaining the original equipment manufacturer's airflow specifications and static pressure requirements.

Common Questions:

What causes a Reznor 55680 motor to fail?
Common failure points include bearing wear due to dust accumulation or capacitor degradation. Replacing with a genuine Reznor motor ensures the torque curve matches the original blower wheel requirements.

Can I use a universal motor instead of the 55680?
While some universal motors share the 1/20 HP 1050 RPM rating, the specific 7/16" D-shaft and FE frame on the 55680 are essential for proper alignment and vibration control in the blower housing.

Is this motor reversible?
This motor is typically set for a fixed rotation to match Reznor fan blade pitch; always verify rotation direction relative to your specific unit heater model before securing the mounting bolts.
