Early chain drive replacement
Chain-drive openers from the early 2000s are reaching the point where the logic board fails or the drive gear strips, and parts for that generation aren't always easy to source anymore, so replacement usually makes more sense than chasing a repair. We also see torsion spring replacement on schedule - springs are rated by cycle count, and a door opened twice a day for twenty years has simply used up its spring regardless of how new the house looks.
