Do a two-minute check yourself every month. Run the door and listen for new grinding, watch that it moves evenly without jerking, and wave something in front of the sensors to confirm it reverses. Noticing a change early is the whole game.
Time your yearly tune-up for spring, before LA’s summer heat bakes the lubricant out and puts the most stress on the springs. A door serviced in May holds up far better through August than one you don’t get to until fall.
