I had a unique speriance'...middle of winter during a storm, stove is CRANKIN'...the wind outside was blowing pretty good so I was keeping an eye on it so it didn't get too rowdy. Anyhow, I hear the typical "pings & twangs" of a stove warming up or cooling down...except it was already hot and shouldn't be cooling down. I looked over and the fire DIED...very big puzzlement indeed. I got up thinking of the possibilities and got almost to the stove VAAAWOOOOOMP....scared the crap outa me and the wife. Still baffled and waiting for it to happen again I picked up a flashlight and went out to see if the cap mysteriously became plugged. Nope. Ran back in and the fire was still struggling. Ran back out and whaala...the cleanout door jostled opened from the wind and I lost draft. I shut the door and made sure it was latched good, ran back in and the stove was operating almost normally again but with more flame than it should have. A little more snooping and I found that the little puffback blew a gaskets out of one of the doors!!.
It can be a little burp or a violent thud.
