I'm trying to tightening up the handle, the two set screws are on the inside of stove correct, I can't get the first one loose,don't want to strip it,any ideas,the only reason I was trying to tighten it up was the handle had a little play in it,but it's been that way for 3 years since I've had the stove. I tried dollar bill trick I comes out with a little tug,I guess just curious how tight the door should be,no smoke smell.or should I just not worry about it ,thanks guys.
