Builder-grade opener lifespan
That gap matters for openers because builder-grade units installed when a house was framed have a working life of roughly 15 to 20 years before the logic board or the capacitor gives out. Houses from 1999 are now sitting right at that edge, and a lot of them are starting to fail the same way: the motor hums but the carriage doesn't move, or the remote works intermittently before it stops working at all.
