That weird trick with a zip tie on a stuck door operator actually worked
I was dealing with this finicky old Otis door operator in a downtown building, kept getting a door open fault even after adjusting the clutch. I mean, I was about to order a new board, but then I remembered this old timer at a training session in Chicago years ago saying you could sometimes reset the cam switch by jamming a zip tie in the track. Figured it was worth a shot, so I cut a tie, wedged it in to hold the switch closed, cycled power, and the fault cleared. The thing's been running fine for three days now. Anyone else ever pull off a weird fix like that to avoid a big parts order?

Yeah I did something similar once on a Schindler door operator. The limit switch was bouncing so I stuck a thin piece of plastic shim under the actuator arm. It ran for another six months before I finally got around to replacing the switch. Sometimes you just need a quick win to keep the thing running while you get the part in.

Wait, so you just forced the switch closed with a zip tie? That sounds like a band-aid fix at best. Isn't that just hiding the real problem, like a worn switch or a bad track? I'd be worried it'll fail again at the worst time.
