Amana-Goodman B1908109 Fan Blade

The Amana-Goodman B1908109 is a 4-inch draft inducer fan blade designed specifically for compatible furnace inducer motor assemblies. This OEM replacement fan blade features a precision-engineered centrifugal design to maintain the necessary static pressure for proper flue gas venting. As a critical component of the combustion cycle, this Goodman furnace inducer blade ensures the pressure switch closes reliably by pulling air through the heat exchanger. The B1908109 utilizes a 1/8" bore with a secure hub attachment, preventing slipping during high-RPM cycles. Constructed from durable materials to resist heat fatigue and chemical corrosion from combustion byproducts, this blade restores factory-spec airflow to Amana and Goodman HVAC units. When replacing a noisy or shattered plastic impeller, ensuring the correct blade pitch and diameter is vital for motor longevity and furnace safety. This part is a direct replacement for various B1908109 inducer impellers found in mid-to-high efficiency gas furnaces.

• OEM Precision: Genuine Amana-Goodman B1908109 ensures exact fitment and balance, reducing vibration that leads to premature bearing failure.
• Optimized Combustion: Designed to maintain specific CFM requirements, ensuring your furnace meets its AFUE efficiency rating.
• Durable Construction: Engineered to withstand the high-temperature environment of an inducer motor housing without warping or cracking.
• Simplified Installation: Standard hub configuration allows for quick attachment to existing 1/8-inch motor shafts.

What causes an inducer fan blade to fail?
Most failures result from heat stress over time or debris entering the housing. If you hear a grinding or rattling noise during the pre-purge cycle, inspect the B1908109 impeller for cracks or missing fins.

Is the B1908109 compatible with all Goodman furnaces?
No, this is a 4-inch blade typically used in specific 80% and 90% furnace models. Always verify the part number against your furnace’s model and serial number or refer to the OEM parts list.

Do I need to replace the entire motor if only the blade is broken?
If the motor shaft is straight and the bearings are quiet, replacing just the B1908109 fan blade is a cost-effective solution for restoring proper draft.
