Common Contractor Questions

Does this board replace the S1-031-01266-000 series?
Yes, this is the current manufacturer-specified replacement for the S1-031-01266-000 and S1-031-01267-000 series 2-stage boards. Always verify your specific model and serial number prefix before installation.

How do I interpret the diagnostic flash codes?
The status LED provides specific flash patterns for common faults, such as open limit switches, pressure switch stuck open/closed, or ignition failure. Refer to the furnace wiring diagram or door plate for the code legend.

Can this board be used on single-stage furnace models?
No, the York S1-031-09162-000 is specifically mapped for 2-stage heating logic. Installing a 2-stage board on a single-stage system will result in improper staging and potential safety lockouts.
