Once every 3-7 years? I've heard of them breaking before but I've never had it happen in a place I lived, including my parents' house growing up, and the houses I've personally owned. I've never had the spring worked on other than to have it installed in the first place. Again, I know they break sometimes. It should not be happening every few years. (But if/when it does, take my money. I'll replace my car's brakes and wire a new ceiling fan but I'm not touching that spring for love nor money.)
