Reznor 64679 Motor

The Reznor 64679 is a heavy-duty, field-ready 115V 1/4HP 1140RPM CCWLE Motor engineered specifically for high-performance unit heaters such as the Reznor UDAP and UDAS series. As a critical OEM replacement blower motor, this component ensures precise airflow management for combustion ventilation and efficient heat distribution in commercial and industrial settings. Built to support single-phase HVAC equipment, the motor operates at a 48Y frame size and draws 5.5 Full Load Amps, providing the necessary torque without overloading the electrical system. The counter-clockwise lead end (CCWLE) rotation is essential for maintaining correct fan blade orientation, preventing backdrafts and ensuring optimal thermal exchange. This permanent split capacitor (PSC) motor is designed for continuous duty within heavy-duty heating environments, reducing operational stress on internal HVAC components while maintaining the consistent static pressure required for larger ducting or open-bay heating applications.

• Precision Compatibility: Direct-drop OEM replacement for Reznor unit heaters, ensuring exact bolt-hole alignment and electrical connection.
• Optimized Performance: Calibrated at 1140 RPM to provide the ideal balance of CFM and noise reduction for industrial workspaces.
• Robust Electrical Design: 115V single-phase motor with a standard 48Y frame allows for straightforward integration into existing electrical panels.
• Sustained Airflow: Engineered for the high-duty cycles of UDAP/UDAS heating units, maintaining consistent airflow through high-demand periods.

What does CCWLE rotation mean for this motor?
CCWLE stands for Counter-Clockwise Lead End. This means the shaft rotates counter-clockwise when viewed from the end where the electrical leads exit the motor housing. Confirming rotation is vital to ensure your heater directs air forward through the heat exchanger.

Can this motor be used in place of an aftermarket generic motor?
While generic 1/4 HP motors exist, the Reznor 64679 is built with specific mounting requirements and thermal protection curves meant for Reznor combustion systems. Using the OEM part ensures the unit operates within its original safety and efficiency parameters.

Which heater models is this motor compatible with?
This motor is the primary replacement for various Reznor power-vented heater series, most notably the UDAP and UDAS models. Always verify your heater’s data plate against the 1/4 HP, 115V, and 1140 RPM specifications.
