York S1-324-36074-436 Blower Motor

When you're dealing with a high-efficiency HVAC system, the York S1-324-36074-436 stands as a critical OEM replacement motor designed to restore factory-spec airflow. This 1 HP ECM blower motor operates on a dual-voltage 120/240V platform, making it a versatile component for varied residential and light commercial air handlers and furnaces. As a veteran tech, you know that the electronically commutated motor design provides significant advantages in torque management and variable speed modulation compared to older PSC models. This unit is specifically programmed ECM hardware, ensuring it communicates correctly with the existing York control board to maintain precise CFM across different static pressure conditions. Whether you're troubleshooting a complete blower failure or inconsistent heating/cooling cycles, swapping in this genuine York part ensures the system bypasses the compatibility headaches often found with universal "equivalents." Its ball-bearing construction and integrated ECM control module are built for continuous duty and high-cycle reliability in demanding environments.

• Dual-Voltage Compatibility: Operates at both 120V and 240V for broad application across different York and Johnson Controls platforms.
• ECM Efficiency: Features a high-efficiency electronically commutated design that lowers energy consumption while providing superior torque.
• OEM Precision: Pre-programmed to match the specific blower curves of your unit, maintaining proper static pressure and airflow.
• Heavy-Duty Construction: Built with high-grade components to handle the thermal loads of constant circulation and variable speed operation.
• Plug-and-Play Integration: Direct OEM replacement ensures terminal configurations and mounting dimensions align perfectly with the factory blower housing.

Is this motor compatible with 208V systems?
Yes, as a 120/240V rated motor, it is typically compatible with standard 208V single-phase power found in many light commercial applications, provided the control signal matches.

Do I need to program this motor after installation?
No, this is a pre-programmed unit designed to drop into specific York models. Once connected to the proprietary control board, it should recognize the factory settings automatically.

What causes an ECM motor to hum without starting?
Usually, this indicates a failure in the ECM control module or a seized bearing in the motor belly. Always check your 24V signal from the board before replacing the entire assembly.

Can I use this to replace a PSC motor?
No, this is an ECM blower motor. It requires a specific control signal from an ECM-compatible board and cannot be directly wired into a system designed for permanent split capacitor (PSC) motors.
