Reznor 195766 Blade

Optimize your unit heater’s thermal management with the Reznor 195766 Inducer Cooling Blade, a precision-engineered OEM replacement designed for high-demand centrifugal blowers. As a veteran-grade inducer motor cooling fan, this component is critical for dissipating latent heat from the venter assembly, preventing premature bearing failure and winding degradation. Specifically developed for Reznor UDAP and UDAS series heaters (ranging from 30 to 175 models), this 2.5-inch plastic blade features a .312-inch bore for a secure press-fit on the venter motor shaft. In the field, a cracked or slipping cooling blade is a primary cause of inducer motor overheating and high-limit trips. Replacing a damaged Reznor 195766 ensures optimal airflow across the motor housing, maintaining the structural integrity of the combustion air delivery system. This HVAC inducer fan blade is the exact factory specification required to restore original cooling performance in Reznor unit heater parts applications.

• OEM Compatibility: Exact replacement for Reznor 195766, ensuring perfect balance and pitch for UDAP, UDAS, UDPA, and RDCA models.
• Thermal Protection: Actively pulls heat away from the inducer motor, significantly extending the service life of the venter assembly.
• Precision Bore: Features a standard .312-inch (5/16") shaft diameter for a direct, slip-free installation on factory motors.
• Industrial Durability: Constructed from high-strength reinforced polymer to withstand the high ambient temperatures of the burner vestibule.

What are the symptoms of a failing Reznor cooling blade?
Technicians typically identify a failing blade by excessive vibration, a high-pitched "whirring" noise, or visible stress fractures in the plastic hub. If the blade fails completely, the inducer motor will often shut down on internal thermal overload.

Is the Reznor 195766 compatible with all UD series heaters?
This specific inducer cooling blade is engineered for UDAP and UDAS models between 30,000 and 175,000 BTU. Always verify your motor shaft diameter is .312 inches before installation.

Does this blade replace the main combustion air impeller?
No, this is the small external cooling blade located on the back of the motor—not the internal squirrel cage wheel used for venting flue gases.
