Spent six hours on a door sensor that just needed a magnet swap

Newer elevator at a 12-story office building in Austin kept phantom opening on the third floor. Turns out the original installer glued the hall door magnet in crooked and it drifted over time. Anybody else waste a whole day on something dumb like a loose wire or bad splice?

Man, crooked glue jobs are the worst. Had a similar thing on a set of sliding doors at a hospital. Someone used hot glue instead of epoxy and the magnet just slid down after a month of vibration. Whole day wasted because the tech who installed it is probably long gone now. Best part is you pull up the old work order and it says "installed firmly" on it. Yeah, real firm like a wet noodle. At least now you know to check that third floor first if the call comes back in.

Ended up dealing with a similar issue last month on an automatic door in a clinic. Swapped the bad glue out for a two-part epoxy and roughed up the surface a bit with sandpaper before applying it. Been three weeks and no callbacks yet, so I'm hoping that's the fix for good.

Is it really that big of a deal though? Hot glue fails fast, sure, but you swapped it out in one day and moved on. Save the anger for something that actually costs you money, not a quick fix.
