Nordyne 667187R Inducer Wheel

When you are dealing with a loud rattling or a failure to prove the pressure switch, it is often the Nordyne 667187R Inducer Wheel that has reached the end of its service life. This furnace inducer blower wheel is a critical OEM replacement part designed specifically for mobile home and residential gas furnaces. Measuring 3 inches by 2 inches, this wheel is compatible with a wide range of Nortek brands, including Intertherm, Miller, and Frigidaire platforms. As a veteran tech knows, a corroded or unbalanced wheel will vibrate the motor housing, eventually leading to bearing failure or a total system lockout.

Replacing a compromised draft inducer wheel is a standard move for maintaining proper combustion air throughput and ensuring the heat exchanger is effectively purged. This specific HVAC blower wheel features a 1/4-inch bore and is built for exact balance to minimize harmonic resonance within the inducer assembly. Whether you are servicing a Nordyne G3, G4, or G5 series unit, using this official component ensures the technical specifications match the motorÆs torque and RPM requirements without overloading the circuit.

Key Benefits for Technicians:
• Direct OEM Fit: Eliminates the shaft alignment issues common with universal "fit-all" aftermarket wheels.
• Optimized Airflow: Precision-angled blades ensure the correct static pressure to engage the pressure switch every cycle.
• Durable Construction: Engineered to withstand the high-temperature corrosive flue gases found in the draft inducer housing.
• Vibration Dampening: Balanced design reduces mechanical stress on the inducer motor shaft and bearings.

What are the symptoms of a failing Nordyne inducer wheel?
Technicians usually identify a failing wheel by an audible "ticking" or "vibrating" sound coming from the inducer assembly. Upon inspection, you may find broken plastic fins or metal corrosion that prevents the motor from reaching its required RPM.

Is this wheel compatible with other furnace brands?
Yes, besides Nordyne and Nortek, this part is commonly used in units labeled as Tappan, Maytag, Westinghouse, and Gibson that utilize the same draft inducer motor assemblies.

What is the bore size for the 667187R wheel?
This wheel is designed for a 1/4-inch motor shaft, which is the standard size for most Nordyne small-frame inducer motors.
