Hit a bad door lock sensor on a 2002 Otis in Chicago yesterday

Spent 45 minutes chasing a ghost fault because the armature gap was off by 2mm, then flagged it for the next PM. You ever have a simple misalignment waste half your morning?

You're telling me a 2mm gap wasted 45 minutes? Maybe the real issue is you were too busy blaming the door lock instead of checking the basics first... I've found half the time when you think it's a sensor problem it's actually something dumb like loose wires or a bad connection somewhere else. If you'd spent 5 minutes doing a voltage drop test you'd have known it wasn't the armature gap in the first place. Chasing ghosts is just part of the job but dont blame the hardware for your troubleshooting steps.

Wait, you're saying a voltage drop test would've caught it before messing with the gap? That honestly never crossed my mind. I used to be totally guilty of jumping straight to blaming the lock hardware (you know, thinking the armature or sensor was just junk) but you make a really good point about chasing bad connections first. I've definitely spent way too much time fiddling with gaps and shims when the real culprit was a corroded wire or a loose terminal. Its frustrating but I guess thats just the difference between guessing and actually testing stuff properly, right?
