The most common call we get from this side of the service area isn't a door that won't move at all - it's a door that reverses halfway up, or an opener that runs but the door barely lifts. On a heavier insulated steel door, that's almost always a spring that's lost tension, not a motor problem, even though the motor is what the homeowner notices straining. In a moderate-heat climate like this one, steel panels and opener sensors can also drift slightly out of alignment as temperatures swing through the day, which shows up as a door that works fine in the morning and refuses to close by afternoon. We check tension and alignment together, because replacing an opener motor on a door with a weak spring just moves the strain back onto the new motor.
