Servicing the Parts of a Garage Door You Never Look At
The parts of a garage door that fail are not the parts anyone looks at. Nobody inspects a centre bearing, a number-three hinge, or the lag bolts holding vertical track to the jamb. All of them are working every time the door moves.

A maintenance visit is mostly about those. The panels are almost always fine. It is the hardware behind them that decides whether the door is still running next winter.
The hardware nobody inspects
Hinges on a sectional door are numbered from the bottom joint upward, and the end hinges carry a roller stem as well, so they take load in two directions and wear oval. Struts across the top section loosen. Lag bolts into the jamb work their way out, and in older garages framed in softer lumber they pull rather than back out cleanly.
Bearing plates at each end of the torsion shaft seize quietly and give no warning at all. We put a wrench on all of it and replace what has actually worn instead of just retightening it and moving on.
Three symptoms that arrive before a breakdown
A door that shudders at the same point in its travel every single time is describing a track joint or a flat-spotted roller, not an opener fault. A lift cable hanging slack while the door is shut means one drum has lost a wrap and the two sides have stopped sharing the load.
And an opener labouring at one specific height, rather than throughout the run, is fighting a mechanical obstruction rather than running out of power. Each of those three is inexpensive now and expensive in a few months.
What gets adjusted, and what gets replaced
The balance test governs everything else. Pull the release, lift the door by hand to about waist height, let go. It should stay put. Drift down and the springs want turns; creep up and they have too many.
From there we reset drums where the cables are unequal, torque the hardware, realign the photo-eyes, and reset the opener's force and travel limits. A door that has been out of balance for a while has nearly always had its force setting turned up to compensate. That setting is a safety device, not a convenience dial, and putting it back is part of the job.

Questions
Naperville questions about this job
How often does a residential door need this?
Once a year suits most. Twice is sensible where the garage is the household's main way in and out, or on a heavy insulated door that works its hardware harder than a light single.
Will maintenance stop a spring from breaking?
Not forever. Springs are consumable and fail by fatigue. What maintenance does is catch the one that is going, so it fails on a scheduled visit rather than on a weekday morning with a car behind it.
Is there anything useful I can do between visits?
Keep the bottom of the track clear, wipe the photo-eye lenses with a dry cloth, and run the auto-reverse test occasionally. Anything involving springs, cables or the bottom brackets should wait for a technician.
