Any Alaska 140 users have a problem with the ash door not wanting to stay shut. I installed the Alaska 140 for my parents last season and it runs extremely well. Upon firing it up this season, the ash door does not want to stay shut. I looked to see if something was preventing it from staying closed but nothing. They did leave the ash door ajar over the summer so the lead cord for the light could run into the furnace. I cleaned the furnace myself at the end of the season and have inspected the ash door and do not see any reason why the door does not stay closed considering it worked fine last season. Question: Could leaving the door ajar allow the gasket on the door to swell. I've never heard of this happening, however, I guess there is a first time for everything.
