On my door and underneath there are only 2 screws holding the hinge mechanism to the door. On the hinge mechanism itself (I took whole thing apart to see this) there are four holes so someone in factory neglected to put the other two in. Easy fix, align hinge, tighten existing screws, drill holes same position as existing screws but on other side of hinge, insert screws or better yet rivets. Probably best to take door off which is simple - lift two tabs pull/push up and out. Perfect fix.
