Amana-Goodman B1908108 Fan Blade

When you're dealing with a failing draft inducer assembly, the Amana-Goodman B1908108 Fan Blade is the exact OEM replacement required to restore proper static pressure. This 3.5-inch ventor fan blade features a 10-blade configuration precision-engineered from a durable composite material to withstand the high-temperature environment of a furnace combustion cycle. Designed specifically for the exhaust side of Goodman and Amana furnace models, including the PG series (36-48), it ensures the efficient removal of flue gases. As a veteran tech knows, a cracked or warped inducer blade leads to pressure switch trip codes and noisy operation; this OEM Goodman replacement part provides the exact balance and pitch needed for the draft motor to meet its RPM specs without premature motor bearing wear. Using genuine HVAC furnace parts like this B1908108 ensures the flue gas velocity remains within safe operational parameters, maintaining the integrity of the heat exchanger through consistent airflow.

Key Benefits

• OEM Precision: Direct replacement for Amana-Goodman B1908108, ensuring zero-modification fitment on existing draft inducer shafts.
• Thermal Stability: Manufactured from composite materials resistant to the heat cycling common in high-efficiency gas furnaces.
• Optimized Airflow: The 10-blade design is factory-balanced to provide steady ventor motor performance and reduce harmonic vibration.
• System Reliability: Corrects "pressure switch stuck open" errors caused by reduced negative pressure from damaged or fouled blades.

Common Questions

• Can I use this blade on other inducer motors? This blade is specifically sized at 3.5 inches for Goodman/Amana induction systems. Always verify the shaft diameter and rotation direction before installation.
• Why did my original fan blade fail? Most failures result from moisture in the flue, debris ingestion, or heat stress. Replacing the blade alone is often a cost-effective alternative to replacing the entire draft inducer assembly.
• Is this compatible with the PG36-48 series? Yes, this Goodman B1908108 is the confirmed specification for those model ranges.
