I'm all for "Right to repair" but I would never suggest a homeowner do their own major repairs or any repairs Involving the safety circuit on an elevator. Like anything, you don't know what you don't know. You could be following all the proper safety procedures from another industry and still do something that gets you or another person killed because of an unknown variable to you. I've seen an electrical engineer add his own soft starter to an elevator and tie both sides of the top final together. And that guy designed things that went into space.
