My apologies! I typed this about 8:00 and never clicked, "post reply"!!!!!
The hose could be cracked" Bullseye!!! The hose was broken at the motor. As soon as I trimmed it clean and put it on, the burner lit! That would explain why it "kinda" had the problem a couple months ago. It probably wasn't completely broken off then.
Thank you, odie 2882 and 67Dart273!!!
I was told when it was installed, (when the house was built), that the fan was because the stack was horizontal, because they didn't want to run a vertical stack through the roof. From your posts, I see that it is what creates a draft. My only experience invoves units with no fan.
It will get replaced in the very near future. Yes, it's 20 years old and overdue. Now I can do a little research and see what unit to use replace it, and shop around a bit. It's been a long time since I bought one and it looks like I'm in for sticker shock!
I never liked the spaghetti plumbing on it.
