PSA: Just hit my 100th call for a stuck door on the same Otis Gen2 in a Boston high rise

It's a building downtown that opened three years ago, and the issue is always the same roller guide on the 14th floor. The building manager finally agreed to let me replace the whole assembly instead of just adjusting it. Has anyone else seen a specific floor cause that many repeat calls on a newish install?

That's a great point about fixing the building. We had a similar thing with a Gen2 where the floor wasn't just off-level, it actually moved. The whole wall the guide was mounted to would shift a tiny bit whenever the HVAC system on that floor kicked on. The temperature change made the metal studs expand and contract just enough to throw the alignment off. Took forever to figure out because it only happened during peak heating or cooling cycles. Sometimes the fix is literally bolting the mounting bracket to the building's concrete structure behind the wall, not just the drywall.

Check the floor's level at that landing.

Been there. A new build in Seattle had a similar ghost call problem on the 22nd floor. It turned out the building was still settling, and the floor slab had a slight dip right at the threshold. Every time a loaded cart rolled over it, the whole landing flexed just enough to knock the guide out of spec. We ended up shimming the entire guide assembly off the wall to match the floor's permanent curve, not the level. Sometimes you have to fix the building, not just the elevator.
