Got chewed out by an older mechanic about my door lock adjustments

A guy with 30 years in the trade caught me adjusting a door lock on a Otis Gen2 last week. He said I was just chasing the symptom not the cause. I was tweaking the interlock position but the roller guides were actually loose and throwing everything out. Next time I checked the guides first and the lock sat perfect without any adjustment. Anybody else learn a hard lesson like that early on?

Chasing the symptom not the cause" - yeah, that stings when it hits home. I had a similar moment with a Schindler 3300 where the doors kept stalling. Spent two days adjusting everything. Finally a senior guy just pointed at a worn door track. Replaced that and it ran smooth. Hard way to learn.

Chasing the symptom not the cause" really does hit different when it's your own time wasted... I had a similar thing with a washing machine that just wouldn't spin. Went through the whole balance ring, the belt, the motor control board. My neighbor came over, looked at it for two minutes, and said "your drain hose is kinked." All that work and it was just water not draining right... Made me feel like the biggest amateur on the planet. Sometimes you just need someone to point at the obvious thing you're too deep in to see.
