Customer Question

I have a York affinity 9.C. 7 red flash error code. I reset the furnace and watched it go through a heat call. The igniter glowed got four different times with no gas lit any time. Do you have a suggestion of what may be the issue?

Russ here. Sorry you are having a problem. This a error code no flame sensed. Three things that can cause problem is no gas to unit,gas valve in off position or bad board.. Listen a see if you here the gas valve click. Russ
