York S1-7990-314P Inducer Motor

The York S1-7990-314P Inducer Motor is an OEM replacement part designed for high-efficiency combustion air delivery in residential furnace systems. Operating at 115Vac, this single-phase, C-frame inducer motor delivers a constant 2900 RPM to ensure proper drafting of combustion byproducts through the heat exchanger. The unit features CCW lead end rotation and is engineered to maintain precisely calibrated static pressure, allowing the furnace pressure switch to prove the draft and advance the sequence of operation to the ignition phase. Professional technicians utilize this S1-7990-314P draft inducer to resolve common furnace failure codes related to venting issues or mechanical bearing failure in older blower assemblies. Its heavy-duty single-speed design provides a direct drop-in fit for compatible York and Coleman units, ensuring that 115V power from the control board translates to reliable, quiet airflow without the excessive vibration common in aftermarket universal alternatives.

• OEM Precision: Genuine York furnace part ensures exact mounting alignment and electrical connector compatibility.
• Optimized Combustion: Sustained 2900 RPM output maintains the negative pressure required for safe gas furnace venting.
• Quiet Operation: Precision-balanced internals reduce mechanical resonance during the pre-purge and post-purge cycles.
• Direct Voltage Matching: Designed specifically for 115Vac systems, preventing control board relay mismatch or under-voltage startup issues.

Is the S1-7990-314P compatible with my furnace?
This motor is the specific OEM replacement induction motor for various York, Coleman, and Luxaire gas furnaces. Professional technicians should verify the CCW rotation and C-frame mounting footprint against the existing data plate before installation.

What are the signs that my current inducer motor is failing?
Frequent indicators include a high-pitched grinding noise from the bearings, the furnace failing to progress past the pre-purge cycle, or specialized "pressure switch stuck open" error codes on the diagnostic LED.

Does this motor include the fan wheel and gasket?
This SKU represents the motor assembly. It is standard practice to inspect the existing squirrel cage wheel for cracks and to utilize a new high-temp gasket when securing the inducer assembly to the collector box to ensure a gas-tight seal.
