We have a 2012 3625RE and the furnace cycled once and then stopped.
The board LED is blinking once indicating an airflow issue.
Nothing is kinked.
I pulled the outside cover off but can't see the sail switch. Also took the cover off in the basement and can't locate it.
Do I need to remove the furnace to access it? I am not by the rig so can't load any pictures.
Appreciate any help!!
We just had the same issue, same single indicator light. Turned out to be lose thermostat wire at the control board. Check to make sure all connections at control board are tight. If not the tech working on ours said itís probably the control board itself.
Good luck. Hopefully itís just the lose wire
