i am on my second year with my 5036 and had the same issue you are having, last year my stove did this 3 times, here is what i did... i kept the door rope clean of crusties and the door face(on the stove), still was having the issue, so i would take off the luvered cover over the dampner door and scrape the crusties off of the damper door were it contacts the main door and also scrape the maiting surface and it seemed to work, but i did this weekly. I was consurned that this was a problem(i shouldnt have to do this so often) My stove was only doing this on warm and most often windy days, so i kept in contact with my dealer about this issue, they were very helpful with giving me suggestions and i tried all of them. I did notice the door rope had a groove in it were it met the stove face and you could tell the door was not square to the stove, one side of the rope in one corner was touching the stove on the edge of the rope, so in the off season i took the door of and took it to the dealer and they replaced the intire door(They agreed the hinge pin holes were not drilled square to the door) also the damper door was not sitting good on the door(very small gap on the top side) so basically my stove was "burning" all the time and it created the "temp creep" issue. I have been burning with the new door( the new one is nice and square to the stove face, rope seal meets stove in middle all around) since middle of sept. this year and have had much better luck, i do still check the crusties on damper door and keep it clean to insure a good seal, but it is a diffrent stove now! hope you get yours figured out..
