York S1-031-09156-000 Control Board

The York S1-031-09156-000 Control Board is a critical replacement component designed for managing fan and electric heat operations within professional-grade York air handlers and furnace systems. As a genuine HVAC OEM replacement part, this board coordinates the specific sequence of operation for AHP series air handlers and compatible electric heating kits. It features integrated logic to regulate blower motor timing and heat element activation, ensuring the system maintains precise airflow while preventing high-limit trips or element burnout. Replacing an aging or shorted unit with this fan/electric heat control board restores the factory-specified timing for HVAC blower motor control, which is essential for preserving the heat exchanger’s integrity and optimizing the overall furnace diagnostic workflow. Its direct-fit design allows for a seamless installation over older legacy boards, utilizing standard wire harness connections to ensure reliable communication between the thermostat and the heating hardware.

• Precise Sequencing: Manages the delay on/off timing for the blower to maximize heat transfer efficiency.
• Direct OEM Compatibility: Engineered specifically for York and Coleman units, ensuring proper fitment and voltage regulation without field modifications.
• System Protection: Includes integrated safety circuits to monitor and react to thermal limit inputs during high-demand heating cycles.
• Enhanced Reliability: Replaces common failure points in older AHP series handlers, such as stuck relays or unresponsive fan signals.

What are the symptoms of a failing S1-031-09156-000 board?
Common indicators include the blower motor running continuously, the electric heat failing to engage after a call from the thermostat, or intermittent system lockouts. If your unit is receiving power but not initiating the fan sequence, the control logic on the board may be compromised.

Is this board compatible with all York air handlers?
While commonly used in the AHP series, you should verify that the part number on your existing board matches S1-031-09156-000 to ensure the relay configuration and harness pins are identical for your specific system footprint.

How do I diagnose a no-fan condition on this board?
Verify 24V input at the thermostat terminals and check for line voltage at the fan output relay. If the board receives a signal but fails to close the relay to the blower, the internal circuit or the relay coil has likely failed.
