Can someone tell me why I should already be needing an new door gasket on a stove that has only been in use less than 3 months? Purchased the stove new from AM/FM in Oct. installed as per directed. Up until a few weeks ago had not had any issues whatsoever. Then it seems as if it takes forever for the convection blower to kick in but once it starts seems to run as should. I do the maintenance as noted in owners manual. Stove has been getting worse on lazy flame and sooting glass. Cleaned stove, pipe and chimney top to bottom and inside and out, no difference. Yesterday I come home and figure after shutdown I will check for air leaks around doors, glass hopper etc as recommended in troubleshooting. All gaskets look good and as stated the stove has been in service less than 3 months. Not only will the door gasket not hold a dollar bill it will slide thru from the top by just sliding it down on about six inches of the door on the topside near hinge end. Check with straight edge and stove has slight bow inward across the top opening. I ordered new gaskets for all yesterday in anticipation of any problems so they should be on the way. I realize these stoves need maintenance but a new door gasket already? I am wondering if after the stove has been in use and the metal has heated and cooled the door gasket no longer seals due to natural warping/curing of the stove. For whatever reason I shouldn't have to be replacing a door gasket already. Anyone else run into anything like this on their stove? Thanks
