What does a rapid red flash on the LED indicator mean?
A rapid red flash typically indicates a twinning error or incorrect 24V phasing. Check your twinning wiring and ensure the transformers are in phase.

Can this board replace an older S1-03102951000 model?
Yes, the S1-031-02951-001 is the official replacement for the older S1-03102951000 and 1162-83-2511A part numbers.

Will this work with a variable speed blower motor?
No, this board is specifically designed for single-stage units and is commonly paired with X13 constant torque motors, not full variable speed (ECM) communication systems.
