York S1-324-36074-313 Motor

The York S1-324-36074-313 is a high-performance 1HP 120/240V ECM Motor designed for precision airflow control in multi-stage or variable-speed York HVAC systems. Operating at dual voltage (120V/240V) with a NEMA 48 frame, this programmed blower motor provides the high torque and efficiency required to maintain static pressure performance in larger residential and light commercial air handlers. As an OEM replacement motor, it comes pre-loaded with the internal logic required for seamless communication with the York system control board, eliminating the need for field programming. For contractors troubleshooting a failed PSC to ECM upgrade or a standard motor swap, this unit features the modular 16-pin control harness and 5-pin power connector typical of GE/Genteq high-efficiency series. Utilizing a York blower motor replacement ensures that the system maintains its original SEER2 ratings and low-decibel operational profile, avoiding the compatibility issues common with universal aftermarket alternatives.

• Pre-Programmed Logic: Configured for specific York airflow profiles to ensure immediate out-of-the-box compatibility with native system controls.
• Dual Voltage Versatility: Hard-wired for 120V or 240V AC inputs, providing flexibility across different furnace and air handler configurations.
• Precision Speed Control: The 1HP ECM motor module maintains constant torque to compensate for varying duct static pressure and dirty filters.
• Quiet Operation: Designed to minimize harmonic noise and provide soft-start/stop ramps that reduce duct "pinging" and mechanical stress.

Do I need a specific programmer for this S1-324-36074-313 motor?
No, this unit is a programmed ECM motor. The 48-program designation indicates the software is flashed at the factory specifically for York equipment parameters.

Can I replace just the module or do I need the full motor assembly?
While the module can often be separated, it is recommended to replace the entire York S1-324-36074-313 assembly to ensure bearing integrity and electrical sync between the rotor and the controller.

What causes frequent failures in these high-efficiency motors?
Moisture entering the module via the wiring harness is a common culprit. Technicians should always ensure a proper drip loop is formed during installation to prevent water from tracking into the 16-pin connector.
