The complaint we hear most from this stretch of Spring Lake is the opener running - motor humming, light turning on - but the door not moving, or moving a few inches and reversing. On a unit this old, that's almost always the drive gear stripped inside the housing, not the motor itself. The second most common call is a door that opens fine but won't close without the opener immediately reversing, which on cold mornings is often a safety sensor that's shifted slightly out of alignment as the slab underneath it settles - not uncommon on a house pushing sixty-five years old. Less often, it's the logic board itself, especially on units that have taken a lightning strike through the power line; those boards aren't always worth chasing down, which leads into the limitation below.
