Got stuck for a whole weekend on a door lock issue that should've been a two hour job
Honestly, I had a call for a stuck elevator in a 90s office building downtown. The car door lock just wouldn't engage, and the controller kept faulting. I figured it was a simple adjustment or a worn roller. Tbh, after checking the obvious stuff, I spent a full Saturday and Sunday tracing a single broken wire in a 50-foot run of conduit between the car top and the machine room. The insulation was fine, but the copper inside had snapped. Has anyone else had a phantom wiring fault eat up that much time? What's your worst 'simple' fix that blew up?
