Our service area sits in a cold climate zone with severe winter conditions, and that's harder on gear-drive and chain-drive openers than people expect. Grease thickens below freezing, chains bind on cold sprockets, and the extra load trips the motor's thermal overload or burns out a capacitor faster than it would in a mild climate. On a house built in 1994, that opener has gone through three decades of those cycles, so when one part fails, it's often not alone - a tired capacitor and worn gear kit show up together more often than either shows up by itself. The other complication is parts availability. Openers from the 1980s and 90s, which still make up a good share of the housing stock across the wider service area, sometimes used drive components or logic boards that current manufacturers no longer carry. When that happens, repair stops being the cheaper option and we'll say so.
