Halfway to spring

Actually, there are two springs, one on either side of the garage door, and at the moment, one of them is not broken, a decrease of one from the day before. (The sound isn’t sprrroingy in the least; it’s a sharp but unresonant Bam!, the sort of noise you’d get if you ordered a robot to bitch-slap Emeril.)

Replacing both springs, I suspect, is the thing to do: I’m reasoning that the inevitable difference in tension between the new spring on side A and the old spring on side B can bring about no good, and will probably break the old spring anyway.

The Amazing Doorman! will be here presently to conduct the repairs, inasmuch as I am not about to mess around with tight coils of metal that would just love to hand off a bunch of kinetic energy, or take my hand off in the process.

    Back before I converted my garage, I had to replace one of my springs. There was a steel safety cable running through the middle of the old spring which kept the broken piece from shooting through the wall and into my living room. I put a new safety cable on with the new spring, so I felt relatively safe with doing the repair.

    Since my door was one of the lightweight metal ones and not made of wood, I didn’t notice any ill effects from continuing to use the remaining old spring with a new spring.

    I’ve done it and yes, I believe it is smarter to replace both springs for exactly the reason you used. It’s not hard for the reasonably mechanically inclined. This was on one of the heavier all-wood doors, so heavy in fact, that without the spring assist I was unable to lift the door at all.

    Well, I did broach the topic; the tech inspected the spring and said that in his opinion, it would not be necessary to replace both at once, provided that the loads were properly balanced, and he made some adjustments to the door hardware and to the opener to improve that balance. (“A little too much slack in the chain,” he said.)

    So that, at least, is out of the way.
