Newbie to the forums here. We have a Hearthstone Heritage 8022 that's two years old. The torsion spring on the side door broke last week. I searched the forums and found some posts from two years ago that let me know this is a known problem for this model and seems to happen repeatedly. Like others who have posted about this I'm concerned about the stone or iron being damaged when the spring breaks or from repeatedly taking the door apart to replace it. Also it just seems from what I've read that it's fighting a losing battle. The questions I haven't been able to find answers to are: Is it necessary to replace the spring? What happens if I don't? Thanks for any insight!
