Reznor 196035 Fan

The Reznor 196035 Ventor Motor Cooling Fan is a critical OEM replacement component engineered for high-performance thermal management in gas-fired unit heaters. This specific 2.25-inch diameter fan blade is designed with a 0.375-inch (3/8") bore to secure directly to the inducer motor shaft, providing essential airflow to prevent motor winding failure. Primarily utilized in Reznor UDAP and UDAS series units, this fan ensures the combustion air blower maintains safe operating temperatures during extended run cycles. As a veteran-grade HVAC inducer fan replacement, it features a 5/8" mounting hole configuration to match factory specifications for the venter motor assembly. Precise airflow across the motor casing is vital for preventing premature bearing wear and thermal overload trips in industrial gas heaters. By utilizing this genuine Reznor 196035 part, contractors can ensure high-efficiency heat dissipation and maintain the integrity of the unit’s venting system without compromising internal clearance or CFM requirements.

Key Benefits

• Optimized Thermal Management: Specifically pitch-balanced to deliver maximum CFM for ventor motor cooling, reducing heat fatigue on electrical components.
• Precision Fitment: Features a standard 3/8-inch bore size for a seamless fit on factory inducer shafts, eliminating vibration and shaft wobble.
• OEM Compatibility: Drops directly into Reznor UDAP and UDAS heater models, ensuring the combustion assembly meets original airflow specs.
• Durable Construction: Built to withstand the high ambient temperatures common in the upper housing of gas-fired unit heaters.

Common Questions

What models are compatible with the Reznor 196035?
This cooling fan is primarily used on the inducer/venter motors of Reznor power-vented units, specifically the UDAP and UDAS series. Always verify the motor shaft diameter before installation.

How do I secure the fan to the motor shaft?
The 196035 utilizes a 0.375-inch bore. Ensure the shaft is free of debris and burrs before sliding the fan into position to avoid fracturing the hub during installation.

Why is my inducer motor overheating without this fan?
The inducer motor operates near the heat exchanger flue; without the ventor motor cooling fan, heat soak can cause the internal thermal protector to trip, leading to intermittent heater lockouts.
