Exclamation NEED HELP searching for a diagnostic DIAGRAM

Hello! I've been over an hour or so, searching for a furnace diagnostic diagram. Specifically this model: G8C15020UHD12A which i've been unable to find. This is a YORK model by the way. It's a quite old model (maybe 8 or 9 yrs old) I've already tried looking it up at many websites with no luck. The thing is that I'm kinda blind with out it. Can someone enlighten me a little bit? Pleasseee? It's getting rrrrreally cold here!!

My suggestion would be to let us help you diagnose the problem with your furnace.

If you want to do that, take the cover off the burner compartment of the furnace. Describe the sequence of events which occur when you turn the thermostat up. Describing that sequence in order and in as much detail as possible is likely to be the key to our helping you.
