Do u have explanation for 9 flashing red lights?

[@birdlegs846]

My york furnace started running the fans came on for about 5 seconds then furnace shut down, had 9 red light flashes and furnace would not run! 1 hour later furnace started running with 1 flashing red light but I do get heat now. Calling repair man tomorrow, going to get cold by sunday below zero.

my york has the one slow red flash, started today, what did your issue end up being?

[@birdlegs846]

Ended up being the control board. Had I known it was for sure the control board I could of replaced the board and save myself a lot of $. Seen a video on how to do it, real easy fix . I seen the video ofcourse after the furnace guy replaced the board, what a rip
