Armstrong Furnace R06428D426 Draft Blower

When you're troubleshooting a furnace that's failing to prove pressure, the Armstrong Furnace R06428D426 Draft Blower (Model ACOMB605-1) is the OEM-spec solution required for a proper repair. This forced draft blower is engineered specifically for Armstrong Air and Allied Air heating systems, including compatibility with Concord, Ducane, and Magic Chef units. It manages the critical combustion air delivery and flue gas venting process, ensuring the inducer motor assembly maintains the necessary static pressure to close the pressure switch and initiate the ignition sequence.

Constructed with a heavy-duty motor and a balanced impeller, this component reduces vibration and mechanical noise during the heating cycle. Utilizing ECM technology in select applications, this assembly provides variable speed control for high-efficiency operation and stable combustion airflows. This unit is a direct replacement for OEM part number R06428D426 and legacy numbers like R03575C000. It features a robust housing designed to withstand high-temperature exhaust environments in residential and light commercial furnaces.

• Precision Airflow: Optimized for combustion stability and efficient venting of flue exhaust gases.
• Broad Compatibility: Fits various Allied Air family models, including 36HWC and 40HWC series.
• Quiet Operation: Balanced internal components minimize resonance and operational noise in the ductwork.
• OEM Standards: Genuine Armstrong replacement part ensuring exact fitment and terminal alignment for quick field installation.

• How do I know if my draft inducer motor is failing? Look for loud buzzing, grinding noises, or the furnace failing to progress past the initial start-up phase because the pressure switch won't close.
• Is the ACOMB605-1 compatible with other brands? Yes, it is a standard component in several Allied Air brands, including Ducane and Concord furnaces. Always verify the part number on the existing blower's data plate.
• Does this include the blower housing? This is a complete forced draft blower assembly, typically including the motor and the housing for direct mounting to the heat exchanger flue outlet.
