York S1-324-36074-440 Motor

For service professionals maintaining York, Luxaire, or Coleman air handlers and furnaces, the York S1-324-36074-440 is a high-efficiency 3/4 HP PRM ECM Motor designed for precise airflow control and system reliability. This OEM replacement motor utilizes Electronically Commutated Motor (ECM) technology to deliver superior performance compared to standard PSC motors, featuring permanent magnet (PRM) construction for lower amp draws and higher torque at various static pressures. As a variable speed blower motor, it is factory-programmed to maintain the specific CFM requirements of 2.0 and 2.3 series equipment, ensuring optimal heat exchange and dehumidification cycles. The programmed ECM blower motor architecture includes a 16-pin communication interface for seamless integration with existing control boards, making it the standard choice for York HVAC motor replacement in residential and light commercial settings where efficiency and quiet operation are critical requirements for the end user.

• Energy Efficiency: High-efficiency ECM technology significantly reduces electrical consumption during continuous fan operation.
• Direct Compatibility: Genuine York OEM motor ensures exact physical fit and electrical match for 3/4 HP specifications.
• Advanced Control: Programmed for variable speed operation to maximize air circulation and reduce noise.
• Durable Design: Built for 230V single-phase systems with heavy-duty bearings for long-term commercial or residential use.

• Does this motor replace the older 3.0 ECM with the silver end cap? No, this unit is designed for 2.0 and 2.3 series architectures; 3.0 series motors generally require a specific replacement kit.
• Is the motor module included and pre-programmed? Yes, the S1-324-36074-440 includes the integrated controller module programmed with York factory parameters.
• What are the symptoms of a failed ECM motor versus a control board issue? Technicians should verify 24V communication signals at the 16-pin harness; if voltage is present but the motor fails to turn, the internal controller or windings are likely compromised.
