15
Had a door operator gearbox let go on a 15-year-old Otis unit last Tuesday
The whole thing started making this awful grinding noise right as the car was leveling. I mean, it sounded like a bag of rocks. Ended up having to pull the motor and replace the whole gear set, which took most of the afternoon. Anyone run into a lot of these failing right around the 15-year mark lately?

Seen a few of those lately. The grease dries out and the bearings go first. Good call replacing the whole gear set.

Wait, the bearings go first?
