I bought a Harman TL 300 12/2010. I use it for three months then I started to have a damper problem. I would open the stove with the handle on the left side. Loaded wood on top and tried to shut the damper once it was time. I could not close it al all. It would not let me push the handle back. This went on for several weeks. I called the dealer and they finally came and replaced the damper frame. Because of the damper not closing the combustion chamber had to be replaced because of over firing. So the dealer replaced the combustion pkg, damper frame and adjusted the damper tension. With that being said I was charged $432.69. ( labor cost. Parts and shipping I was charged ) One month later same problem. Ok by this time I have had it. They came back and repaired damper again. Told me not to use stove because combustion chamber damaged. So had to wait to be replaced again.. Spring came and I just started using the stove this year in January. Yes it happened again. Loaded stove and could not shut damper over fired. And yes here we go again. Does any one else out there have this issue. PLEASE HELP ME.
