I have a york diamond 8o it haves a white rodgers broad model # 50a50-241
The led ligth flashes 8 times can you tale me what that error code is.
Thank you for your help.

The legend should be inside the blower access panel or on the board housing, if present.

I think the fault codes on the 50a 50 board are on the board itself

8 flashes = lockout caused by loss of flame
