York Coleman Draft Inducer Assembly S1-7990-6451

York / Coleman S1-7990-6451 Draft Inducer Booster Assembly | 120V, 2950 RPM

Restore reliable ignition and safe, positive-pressure exhaust venting to your furnace with the genuine York / Coleman S1-7990-6451 Draft Inducer Assembly. Also classified under Source 1 factory parts, this premium motorized combustion blower is engineered specifically for specialized downflow gas furnaces under the Coleman, Evcon, and York badges. Operating at a high-velocity 2950 RPM, this pre-assembled booster blower draws a precise volume of air into the burner enclosure to establish proper drafting, while safely forcing hazardous flue gases out through your structural chimney vent pipe.

As an authentic factory OEM component, the York S1-7990-6451 Inducer Assembly comes with the blower wheel and housing balanced straight from the manufacturer, eliminating the intrusive vibration, premature motor failures, and pressure switch faults common with generic aftermarket assemblies.

Why Buy From Shortys HVAC Supplies?

At Shortys HVAC, we deal strictly in Original Equipment Manufacturer (OEM) and top-tier factory-authorized components. Lower-grade universal draft inducers often carry slight sizing variations or improper RPM curves, leading to failure of the furnace's pressure switch loop and leaving you without heat during extreme winter weather. Investing in an authentic factory part preserves your equipment's operating efficiency, structural safety listings, and active manufacturer warranties.
