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.
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.

Scene 1
The assessment begins with the opener out of the picture. The technician closes the door, pulls the red manual release so the trolley disconnects, and lifts the door by hand to about a metre, then to full height, then lets it settle. A balanced door pauses wherever it is stopped; a door that climbs on its own has too much tension, one that drops has too little, and one that is fine low down but drifts up near the top can point to drum profile, cable length, uneven section weight or the spring's own characteristics rather than one single cause. How much effort the lift takes and whether it stays fully open are noted before anything is adjusted.
Scene 2
With one winding bar seated firmly in the winding cone and a second ready, the technician loosens the cone's set screws and either adds tension by levering the bar upward or releases it by letting the bar down, always a quarter turn at a time, always with a bar in the cone. After each quarter turn the set screws are tightened onto the shaft, the clamp is removed and the door is lifted by hand to test. A door that sank now holds a little higher; a door that climbed now settles. On a two-spring door the same change is made to both springs so they share the load equally.
Scene 3
A balanced door lets the opener's safety settings stay at sensible values, and it is worth keeping them there. If the door ever starts to reverse for no reason or struggles to lift, resist the temptation to turn the force up on the motor; that hides a door that has grown heavy again and takes the entrapment protection out of its proper range. Instead, release the door and try the hand test. If it no longer holds, the springs want attention, and a balance adjustment puts the weight back on them so the opener can remain at the gentle settings it was left with.
What shapes the quoteChippawa Garage Door Pros
FeesSame any hour
A torsion door has springs on a shaft above the opening, and tension is changed by winding the springs with steel bars, a quarter turn at a time. An extension door has springs along the tracks, and tension is changed by moving the hook or cable clip to a different position with the door open and clamped. The hand test that proves the result is the same for both.
Yes, and installers will usually insist on it. A new opener is set up against the door it meets on the day, so its travel and force settings are only right if the door is already balanced. Fitting a new motor to a heavy door shortens the motor's life and puts the safety reversal out of range. Balancing first means the new opener starts life doing the light work it was designed for.
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.
