Reply to comment by UnfairAd7220 in Garage door opener system failure-anyone want to share if you know estimate to have it replaced? by Stickyfynger
You install the spring in the unloaded position. There’s literally no tension at all when you’re working on it. Then you leave the garage entirely and use the remote opener to test if it’s working.
It’s really not rocket (or bomb) science…
