• Multi-Motor Support: Designed to interface seamlessly with PSC or ECM blower motors for broad equipment versatility.
• Advanced Limit Logic: Engineered to monitor performance and safety, reducing the frequency of hard lockouts during demanding heat cycles.
• High-Efficiency Regulation: Precisely manages the timing of electric heating stages to ensure consistent discharge temperatures.

Is this a universal control board?
No, the S1-031-01264-002 is a specific York OEM part. Always verify your model number, as it is designed specifically for York, Coleman, and Luxaire air handlers and electric furnaces.

Why is my blower fan running constantly or not at all?
Faulty relays on the control board often cause fan failure. If the board receives a G signal but does not output line voltage to the motor, the board likely requires replacement.

Does this board require specific wiring for electric heat stages?
Yes, this board manages the sequencing of heating elements. Ensure W1 and W2 signals are correctly landed on the terminal strip to prevent uneven heating or system tripping.
