That doesn't look like a Lennox model number (more like a serial number). Could you double check. If it's right it must be an old model if you have a pilot you can light. If that's the case do you have a wiring diagram (often affixed to the inside of one of the panels). A clearly focused picture of the wiring diagram would help.

Yes, I'm here. Give me a few to look up specs on your unit

That's a coil model number. Look inside the burner compartment the model should be on the rating tag

I have to step away for 15 to 20 minutes. I'm going to ope this back up to my colleagues so you don't have to wait. If nobody picks it up before I get back we can continue.

Not sure where that is
I got the model off theLennox tag on outside of furnace
When I open the two panels is see a blower
On bottom
And the igniter on top

Ok, sometimes the label is on the outside but you gave me the AC coil not the furnace model number. Did you look inside where the burners are?

If you can't find the model number some pics might help. One of a wiring diagram would be ideal
