York S1-324-36074-547 Motor

The York S1-324-36074-547 Motor is a high-efficiency 3/4HP ECM blower motor designed for precision airflow management in York, Luxaire, and Coleman residential furnaces and air handlers. As an electronically commutated motor, this OEM replacement motor utilizes an integrated microprocessor to maintain constant CFM against varying external static pressure, ensuring optimal heat transfer across the DX coil or heat exchanger. This 120/240V programmable ECM motor is engineered to replace failing induction motors or older generation ECM modules, providing variable-speed operation that significantly reduces energy consumption and operational noise. For technicians, this HVAC blower motor replacement ensures a drop-in fit with the correct 5-pin power and 16-pin control harnesses. Its variable speed blower motor technology allows for enhanced dehumidification profiles and consistent indoor air quality. When diagnosing air circulation issues, verifying the 24V control signals from the furnace board to this 3/4HP blower motor is essential for confirming module functionality before swap-out.

• Direct OEM Replacement: Ensures full compatibility with York and Source 1 equipment specifications without the need for mounting modifications.
• Advanced ECM Efficiency: Reduces electrical draw compared to standard PSC motors, optimizing the system's SEER2 ratings.
• Constant Airflow Technology: Automatically adjusts torque and RPM to overcome restrictive ductwork or dirty filters, maintaining programmed CFM.
• Quiet Startup: Features soft-start ramps that eliminate the "thump" of sudden air pressure changes in the plenum.
• Precision Control: Supports multi-stage and modulating furnace operations for superior temperature staging and humidity control.

Is this motor pre-programmed for my specific furnace model?
Yes, as a genuine York S1-324-36074-547, this unit is programmed with the specific airflow parameters required for compatible York HVAC assemblies. Always verify your unit's serial number to ensure the program matches your cabinet size.

Can I replace just the control module or do I need the entire motor?
While the ECM microprocessor can sometimes be sourced separately, replacing the complete 3/4HP ECM blower motor assembly is recommended to resolve bearing wear and electrical winding issues simultaneously, ensuring long-term reliability.

Will this motor work with both 120V and 240V systems?
This motor is designed for dual-voltage applications. Technicians should verify the presence of the 120V jumper on the 5-pin power connector to match the line voltage of the furnace or air handler during installation.
