If you’re going to work on your garage door yourself, remember that those springs have a hell of a lot of tension. You accidentally let one of them loose, and they’ll have enough force to gravely injure you.
Thanks. Not going near the springs. I’ve seen many posts where people want to replace them themselves and everyone advises against it. I’ve worked on the motor unit before - the gears (nylon I think) had gotten chewed up somehow and I replaced them.
There’s no need to touch the springs at all when replacing the opener. But this is still an excellent PSA. Garage door springs will seriously mess you up before you even know what happened. I’ve replaced them before, but you definitely need the right tools and procedures to do it safely. I would definitely advise against it unless you have experience.
