The call usually starts one of two ways. Either the opener won't respond at all - no light, no hum, nothing when you hit the button - or it hums and strains but the door doesn't move, which almost always means the motor is fine but something downstream (track, rollers, or a dying capacitor in cold weather) is taking the load it shouldn't. Homeowners in this area, where median household income runs well above the national figure, tend to go straight for full replacement rather than patch a ten-year-old unit, and for an opener that old that's often the right call - parts support thins out fast once a model's been discontinued.
The other common version: the opener works, but inconsistently, especially on cold mornings. That's the capacitor-and-grease pattern we see a lot in this climate band. It's worth describing which version you've got when you call, because it changes what we bring on the truck.
