Furnace: Lennox G43UFImageThe little red attempt at a bolt in the upper left of the photo is where the bolt for the flame sensor is located but in the back. I can barely get my hand back there, so I'm kind of worried if I take it out I may not manage to get it back in.It does look like the front could come off with the 4 bolts, but I have no idea if that's safe or not. I know enough to shut off the gas and electricity, but you know, IDK if it's sealed or something. Sadly it's the weekend so I can't get a pro in here until the week starts.Any suggestions would be welcome, I am so frustrated with how difficult it is to get to such a common problem area, and I'm cold to boot. via /r/DIY http://ift.tt/2F7E5jW
