This part of the service area sits in a cold-moderate climate band, and winter is harder on openers than most homeowners expect. Grease in the drive gear stiffens in the cold, the motor pulls more current to move the door, and over a few winters that extra load is what finishes off a capacitor that was already marginal. Houses from 1989 onward typically have insulated garages tied into the house envelope, which helps some, but an opener mounted near an uninsulated header still takes the brunt of temperature swings season after season. Compare that to the pre-1960 stock found elsewhere in the broader service area, where openers were often retrofitted onto original hardware built for hand operation - Leawood's garages were built with an opener in mind from day one, so the failures here tend to be mechanical wear and cold-weather strain on a mature system, not a hardware mismatch.
