Hi LuvstheSon;
Welcome to the forum.
I've never had the door get stuck this bad, but on occasion have had it get stuck. It appears that the reason your door is getting stuck is that you are not cleaning the seal, and the door frame the seal comes into contact with. Periodically clean those areas with isopropyl alcohol, and a piece of cloth or paper towel. Smoke will build up in those areas, and it become an adhesive if it builds up too thick.
Depending on how cold it is outside, the hairdryer should help. As you heat the area use a plastic putty knife, or silicon scraper/spatula to pry the seal away from the door frame. After you get it opened give the seal and door frame a good cleaning.
