Reznor 196243 Motor

For service technicians maintaining Reznor unit heaters, the Reznor 196243 Motor is the direct OEM replacement fan motor designed for high-static and standard airflow applications. This 115V, single-phase 1/30 HP HVAC motor operates at a fixed 1050 RPM, delivering the precise torque and velocity required for Reznor UDAP-100 and comparable series heaters. Built with a 42Y NEMA frame and an Open Air Over (OAO) enclosure, this unit facilitates continuous duty by leveraging the system's own airflow for thermal management.

The motor features a 1/2-inch diameter shaft with a flat design, ensuring a secure fan blade attachment without slipping under load. With an amperage draw of approximately 2.7A and automatic thermal overload protection, it safeguards the internal windings from overheating during high-demand cycles. Integrating this genuine Reznor part ensures that the combustion blower and air distribution systems remain within factory pressure and temperature specifications, preventing common safety circuit trips associated with generic "equivalent" motors.

Key Benefits

• Direct OEM Compatibility: Specifically engineered for Reznor UDAP-100 unit heaters to maintain factory-spec airflow and static pressure.
• Thermal Safety: Equipped with internal thermal overload protection to stop the motor in the event of an restricted intake or mechanical failure.
• Simplified Installation: Features a 37-1/4 inch lead length and extended stud mounting for rapid swap-outs in the field.
• Reliable Performance: The 1050 RPM 115V motor design provides consistent heat exchange efficiency in commercial and industrial environments.

Common Questions

Is this motor compatible with 208V or 230V systems?
No, this is a dedicated 115V single-phase motor. Applying higher voltage will result in immediate winding failure.

Does this include the capacitor?
This specific motor is typically a shaded pole or permanent split capacitor design. Please verify the wiring diagram on your specific heater model, as some configurations may require a separate run capacitor if not internally mounted.

Can I use this motor for other Reznor models?
While it is the primary motor for the UDAP-100, always check the MPN 196243 on your existing motor plate to confirm the HP and RPM match your chassis requirements.
