Slightly embarrassed to ask this, but I'd like some feedback.... was watching TV with the wife and heard a loud banging coming from above us. We heard a total of maybe 4-5 loud bangs over the span of 5-10 min. It startled us both and I want outside to see if a tree branch had landed on the house or something. After finding nothing I am thinking it must have been the stove pipe. Did I have a chimney fire? There was no jet engine wooshing sound that others have talked about. When I was outside, I didn't see anything crazy coming from out of my stack, just normal minimal white smoke. stove temps were around 650 and magnetic flue thermometer was reading high, close to maxed out, flue damper was completely closed. So I'm not sure how I was getting temps that high with damper completely closed and air about 1/8 open. I burned wet wood last winter for about 3 months as that's all I had access to so I'm sure I had some creosote buildup. I have a chimney sweep scheduled to come in two days but I have a feeling it'll be rescheduled out a week or two due to rain in the forecast. I was hoping to not burn before the sweep came, but it's been cold so I figured I could get away with doing a few fires. New stainless steel 6" liner was installed last November. Should I hold off on burning until I can get it swept and inspected? I plan on doing a visual inspection of the liner today when I get home from work. Any suggestions on what to look for?
