York S1-373-19801-821 Inducer Motor

The York S1-373-19801-821 Inducer Motor is an essential OEM replacement component designed to maintain the integrity of the combustion cycle in high-efficiency gas furnaces. Engineered for York, Coleman, and Evcon systems, this 115Vac draft inducer operates at a precise 3300 RPM to facilitate the safe expulsion of flue gases. Its CW lead end rotation (CCWSE) and 1/150 HP rating ensure it meets exact factory airflow requirements, preventing pressure switch trips and furnace lockouts. As a veteran-grade combustion blower assembly, it features ball bearings for increased durability and efficiency over standard sleeve bearing alternatives. Technicians will find the S1-37319801821 is a direct drop-in for legacy part numbers 373-19801-820 and 65475, maintaining the furnace exhaust venter performance standards required for DGAA and DGAH series units. This OEM furnace motor includes the necessary 4-inch wire leads with molded plastic plugs for a secure, moisture-resistant electrical connection during installation.

• OEM Compatibility: Specifically calibrated for York and Coleman furnace combustion systems to ensure correct static pressure.
• Enhanced Durability: Equipped with dual ball bearings to minimize friction and extend operational life in high-heat environments.
• Efficient Exhaust: The 3300 RPM motor speed provides the high-velocity draft required to move flue gases through restrictive secondary heat exchangers.
• Direct Fitment: Eliminates the need for field modifications, featuring standard mounting patterns and pre-terminated wiring.

Is this a direct replacement for part number 373-19801-820?
Yes, the S1-373-19801-821 is the official updated version and directly replaces the older 373-19801-820 and S1-373-19801-820 models.

Does this inducer motor come with a gasket?
While many OEM assemblies include a mounting gasket, it is standard professional practice to verify the condition of the existing seal and use high-temperature silicone or a new inducer gasket to prevent exhaust leaks.

Why is my furnace calling for heat but the inducer motor won't spin?
If 115V is present at the motor leads but the shaft doesn't turn, the venter motor has likely seized or suffers from an open winding. If no voltage is present, the issue may reside in the integrated control board or thermostat circuit.
