Reznor 194687 Assembly

The Reznor 194687 Assembly is a high-performance 115V vent motor and wheel assembly designed for exact fitment in Reznor unit heaters. This centrifugal blower assembly, which is the direct replacement for the legacy part number 97730, is engineered to restore proper drafting and combustion airflow in gas-fired heating equipment. Operating at 115 volts, this replacement inducer motor features a robust motor housing and a precision-balanced wheel to minimize vibration and bearing wear. For technicians performing HVAC furnace repair or seasonal maintenance on Reznor F and B series units, this assembly ensures the pressure switch circuit closes reliably, maintaining system safety and efficiency. The drop-in design allows for immediate installation without field modifications, ensuring OED burner performance remains within manufacturer specifications. Keeping a Reznor 194687 on the truck is essential for resolving common inducer fan failure issues during peak heating seasons.

Key Benefits

• Direct OEM Interchange: Fully compatible with units requiring part number 97730, ensuring zero-clearance issues during installation.
• Optimized Airflow Dynamics: Precision-engineered wheel geometry provides the exact static pressure required for safe flue gas venting.
• Heavy-Duty Construction: Built to withstand high-temperature flue environments, preventing premature motor burnout and warping.
• Reduced Operational Noise: Balanced internal components limit harmonic resonance within the heat exchanger cabinet.

Common Questions

Is this motor compatible with the older 97730 part number?
Yes, the Reznor 194687 is the direct superseded model for 97730; the specifications and mounting patterns are identical.

What are the electrical requirements for this assembly?
This is a standard 115V single-phase motor. Always verify the voltage at the leads before wiring to prevent capacitor or winding damage.

How do I know if the inducer motor needs replacement?
If the sequence of operation stalls at the pressure switch or if you detect heavy bearing noise or "seized" resistance in the wheel, a replacement vent motor is required.
