With the door closed, daylight shows under one bottom corner and the seal is squashed flat at the other. As it rises, the left side leads by an inch or two, and the top section twists slightly as it turns into the horizontal track.
Older detached garages often have extension springs stretched along each horizontal track rather than a shaft above the door. Balancing these works differently: the tension comes from how far each spring is stretched when the door is closed, and it is set by moving the cable attachment along the track hanger or changing the hook position. Both sides are adjusted equally so the door stays level, and the containment cable running through each spring is checked at the same time. The door is opened and clamped so the springs are relaxed during the work, then tested by hand across its travel until it rests where it is left.

Scene 1
A door that is out of level is usually a cable story rather than a spring story. The technician checks that each cable wraps its drum in a single neat layer with the same number of wraps on both sides, that the drum set screws are tight on the shaft, and that neither cable is frayed or rusting at the bottom bracket. A tape across the bottom of the door in the closed position shows whether one corner sits high. If it does, the cables are reset on the drums so the door is level before spring tension is judged, because a crooked door binds in its track and feels heavy regardless of how the springs are wound.
Scene 2
The visit is finished only when the standard tests pass. The technician places a piece of two-by-four flat on the floor in the door's path and closes it with the wall button; the door must strike the wood and return to fully open. Then, with the door closing again, an object is passed through the photo-eye beam, and the door must reverse. Finally the door is released once more and the hand test repeated so you can see it hold at knee height, at waist height and fully open. These are the same checks the door industry's own maintenance checklist uses, and you are welcome to watch each one.
Scene 3
You can repeat the balance test any time without touching a spring. With the door closed, pull the manual release cord so the trolley disconnects, lift the door by a handle or a safe gripping point to about a metre, and let go gently. A balanced door stays roughly where you leave it; one that creeps up or sinks has drifted and is worth a call before it becomes heavy work for the opener. Reconnect the opener as its manual describes, usually by running it once. Doing this at the start of each season, when the temperature changes, is the simplest way to catch a change early.

It is the manual release. Pulling it disconnects the door from the opener's trolley so the door can be moved by hand, which is how the balance test is done and how you get the car out during a power cut. The industry standard calls for it to be red and reachable, no more than about six feet above the floor. Reconnecting is usually as simple as running the opener once.
Yes, and it is one of the most common reasons a door starts to sink. Springs are matched to the door's weight, and insulation kits, replacement sections, windows or a heavier seal add weight the original springs were not sized for. A technician can weigh the door and either add tension to suit it or, if the added weight is beyond what the springs can carry, specify new ones.
Too much spring tension. The springs are pulling harder than the door weighs, so at rest they win and the door climbs. This often follows a spring replacement wound a turn too far, or a door that lost weight when heavy panels were swapped for lighter ones. Releasing a quarter turn or two, tested after each, brings it back to holding still.
