Because most Holts Summit houses are newer, the failures we see here skew differently than in the older parts of the county. You're less likely to be dealing with a worn-out chain-drive unit from the 1980s and more likely looking at a circuit board failure, a stripped gear in a belt or chain unit installed when the house was built in the early 2000s, or safety-sensor wiring that's degraded over twenty-some years of winters. The cold climate band this area sits in means condensation and temperature swings inside an unheated garage shorten the life of plastic gears and sensor eyes faster than a heated space would. If your opener motor runs but the door won't move, or the light blinks and the door reverses before it closes, that's usually the sensors or the board, not the motor itself - and it's often a repair, not a full replacement. We'll tell you which one it is before we recommend a new unit.
