Nordyne 903773 Blower Assembly

The Nordyne 903773 Blower Assembly is a direct OEM replacement HVAC blower designed specifically for 3-ton residential furnace and light commercial air handler applications. This complete assembly is engineered to restore static pressure performance and factory-spec airflow, featuring an 8-inch housing and a 3-speed motor configuration. Operating at 115V single-phase power, the integrated 1/4 HP motor provides versatile speed taps at 1075, 950, and 810 RPM, allowing for precise CFMs to match your system's ductwork and heating or cooling requirements.

For technicians servicing Nordyne, Miller, Intertherm, or Broan equipment, the Nordyne 903773 eliminates the need for field modifications common with "universal" fit motors. The genuine Nordyne furnace parts construction ensures proper mounting alignment and electrical connector compatibility, reducing labor time during blower motor assembly swap-outs. By installing a factory-authorized blower assembly, you maintain the original system efficiency and quiet operation expected from 36,000 BTU nominal capacity units.
