Afternoon drag on one side
The door starts dragging on one side of the track around midday, runs fine again by evening once the metal cools back down. Owners usually blame the opener first, because that's the thing with the motor, but the opener is rarely the cause on a new door - it's almost always track that was set too tight for the severe heat swing this area runs, or a jamb that wasn't quite square when the track got bolted to it.
