Common Questions

Is the S1-331-02972-000 compatible with first-generation York modulating furnaces?
This is a 2nd generation control kit. While it replaces several previous iterations, you must verify the serial number of your unit as some older modulating stacks require specific harness modifications or firmware revisions.

Does this board support variable-speed ECM blower motors?
Yes, this York furnace control board is designed to communicate with ECM motors to provide the variable airflow required for high-efficiency modulating heating cycles.

What are the symptoms of a failing S1-331-02972-000 board?
Typical failure indicators include erratic gas valve modulation, intermittent blower relay failure, or repetitive "lockout" fault codes that do not clear after sensor cleaning or replacement.
