Rant: My stubborn habit of not checking the governor rope tension first cost me a whole morning

I was chasing a weird intermittent door fault on a 15 year old Schindler for two hours, pulling my hair out. The old guy I was training with just reached over, gave the governor rope a firm tug, and said 'Kid, you're looking for a ghost in the machine.' The slack was obvious once he pointed it out. Anyone else have a simple step they used to skip that always comes back to bite them?

That "ghost in the machine" line hits home... I used to skip checking the door zone clearances on the old Dover Miproms. Would spend an hour on a call back for a door reopening, only to find a worn roller bracket letting the door drift just a quarter inch out of zone. Now it's the first thing I look at before I even open my tool bag.

The Miprom door zone is a classic. I saw one last month where a bent sill plate, maybe an eighth of an inch out, caused a week of nuisance calls. You start chasing limit switches when the problem is just the door hanging up on the way out.
