Frequently Asked Questions

Is the York S1-324-40874-002 a drop-in replacement?
Yes, this is a genuine York replacement part. Because it is an ECM motor, it is pre-programmed with the specific parameters required for your specific model's blower housing and wheel size.

Can I use this 115V motor in a 230V system?
No. The York S1-324-40874-002 electrical specs are strictly for 115V applications. Installing this on a 230V circuit will cause immediate electronic failure of the motor module.

Why should I choose an ECM motor over a PSC motor?
An ECM blower motor is more efficient and provides better dehumidification and filtration by adjusting its speed based on the system's demand, unlike fixed-speed induction motors.
