Two things drive opener failures in this area more than anything else: age of the housing stock and the cold. With most homes dating to the 1959-1988 window, a huge share of openers out there are either original equipment or a first-generation replacement, both well past the point where plastic gears and old capacitors hold up.
Then there's the cold. This area sits in a severe cold climate band, and that kind of winter is hard on an opener's moving parts. Grease thickens, nylon gears get brittle, and a motor that strains to pull a door through frozen track seals wears out its gears faster than one running in a mild climate. We get a real jump in opener calls on the first hard cold snap each year, right when owners are already trying to get the car out before work.
If a part isn't in stock, the nearest wholesale supply house is in Berea, about 10 miles out, so even an unusual job typically still turns around the same day.
