I have a 21 year old Carrier oil furnace that yesterday started making
an unusual smell, hard to describe, maybe sort of acrid.
Tonight, at the start of the weekend of course, I found a modest
amount of "smoke" curling up from both the left and right sides of the
burner. On the left it's right between the round air intake and the
wall with the fire chamber on the other side. On the right, no air
intake but same place.
I haven't used a mirror to get a better idea of the source. It's sort
of hot when the furnace is running.
I thought until Monday I could just plug the hole with GE Hi-temp
silicone sealant. I've seen that used on my neighbor's identical
furnace and it doesn't seem damaged by the heat. But I haven't found
Of course tonight is Friday, and it's cold out, so I'd like some
advice to get through the weekend warm but without making things
worse. Or maybe until the middle of march, when I'm going away for
two weeks and I shouldn't need heat when I get back.
The CO detector is brand new, upstairs in my bedroom and shows zero
CO, although I really have no way of knowing if the detector was bad
when I bought it. I guess they test each one at the factory?
Any help would be appreciated.
