The door has grown heavy so gradually you stopped noticing, until a visitor tried to lift it and could not. The opener still manages, but it sounds strained, the chain slaps on the way up, and the wall button gets pressed twice most mornings.
An opener is designed to move a door that is already balanced, and every safety feature in it assumes that. The force it applies is limited so the door will stop and reverse when it meets something, and that limit only makes sense when the door is close to weightless. When springs lose tension, the opener has to lift real weight, its motor and gears work harder, and it may reverse or stall for no obvious reason. A balance adjustment puts the weight back on the springs where it belongs, so the opener can return to the light duty it was built for and its reversing behaviour is dependable again.

Garage Door Balance Adjustment · Stoneybrook
Scene 1
On a door with springs along the tracks, the check has a shape of its own. Both springs are compared for length and coil condition with the door closed, since a spring that has stretched further than its partner leaves one side of the door lighter. The pulleys are spun for wear, the cable clips on the track hangers are checked for equal position left and right, and the technician confirms a containment cable runs through the centre of each spring and is anchored at both ends. The bottom brackets and the S-hooks that set the spring tension are inspected for rust and deformation before any adjustment is planned.
Scene 2
If one corner of the door sat high, that is corrected before the final tension is set. The technician releases the spring tension enough to take the load off the drums, loosens the set screws on the drum on the low side, takes up or lets out cable until the door is level, and locks the drum again with the cable seated snugly in its groove. The bottom of the door is checked against the floor along its whole width, and both drums are confirmed to show the same number of wraps. Only then is the spring tension brought back up, because tension applied to a crooked door simply loads one side more.
Scene 3
Once a month, with the door closed and the light on, look up at the drums and down at the bottom brackets. Each cable should wrap its drum in a single neat layer with the same number of turns on both sides, and hang taut without fraying or rust at the bottom loop. The gap under the door should be even from corner to corner. On an extension door, glance at the two springs for equal length and confirm the containment cable still runs through each. These take less than a minute and tell you the door is still level and the counterbalance still shares the load evenly.

Two are standard. A piece of two-by-four is laid flat on the floor in the door's path and the door closed onto it; it must reverse and return to open. Then, as the door closes, an object is passed through the photo-eye beam near the floor, and again the door must reverse. Both depend on a balanced door, which is why they come after the adjustment rather than before.
With the door closed, the opener is released so the door is free. It is lifted by hand to about a metre, then to fully open, and let go at each point. A door in balance holds its position; one that rises on its own is over-tensioned and one that drops is under-tensioned. The door should also move freely and no faster than the hand pushing it.
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.
