I got it!, After pulling the fridge and cleaning the chimney and baffle I'm back in business. I want to thank most of you for all your suggestions. The chimney was not dirty, and no soot at all, just some light scale rust. The baffle was complete and intact with some very light scale rust. Cleaned it all up and put it back together, and now it's working great.
As an ugly side note, there is a poster on here who claims to know it alli. I was told by him, in a previous thread, YOUR CHIMNEY DOES NOT NEED TO BE CLEANED.. The same guy that accused me of lying about my water column pressure, cause apparently we're all to stupid to perform these simple tasks. We're all wrong sometimes.
I was once...back in '92!!
