It is a look and a record first. Small maintenance items such as lubrication, cleaning and aligning the photo eyes and tightening fasteners can be done on the spot if you wish. Anything involving spring tension, cables, drums, worn rollers or damaged sections is written up with a clear explanation and quoted as its own job, so you decide with the full picture in front of you.

The usual causes are an impact from a vehicle, a lifting cable that broke or slipped off its drum, ice holding the door to the floor while the opener pulled, an obstruction under the door, worn rollers that no longer hold in the rail, or track brackets that have loosened from the wall. Finding which one applies is the first part of the visit, because the reset is only durable once the cause is corrected.

Sometimes. The flag bracket at the top of the vertical track usually carries the bearing for the torsion shaft, so if that bracket or the curve has to move, the springs are unloaded first with winding bars and rewound afterwards to the same turns. Simple work on the vertical run below the curve, or on the horizontal hangers, can often be done with the springs left alone. Either way the door is balance-tested at the end.

Watch for a door that feels heavier by hand when the opener is released, an opener that strains or slows, a door that drops the last stretch rather than settling, or one that drifts down when stopped halfway. Visually, look for stretched gaps between coils, rust streaks or pitting on the steel, and any sag in the shaft. A balance check when you notice these lets you plan a replacement rather than react to one.
