Don't sweat it! JennAir also had issues with the door, particularly the hinges failing. Even though they do not appear to sag, they are not allowing the door to close properly or uniformly. The solution is new door hinge and is Maytag part # 74011142. Comes with instructions also. Might as well replace them both.
p.s. You would not have cold air coming up the downdraft if you had a proper damper installed.
