Halfway up, the door hesitates and the opener strains before it carries on. Pulled by hand with the opener released, you feel the same catch at the same height, as if a wheel is dragging instead of turning.
Not every roller suits every door. Wheel diameter has to match the track: two inches on residential track, and either two or three inches on commercial track, so the installed track is measured, not assumed. Stem length has to match the hinges: four inches through a single hinge, seven or ten inches where two hinges stack at the end of a heavier door. Bearing count and load rating have to suit the door's weight, with insulated steel and wood doors needing more than a light single-skin door. Measuring all of that before a set is chosen is part of the service, so the new rollers sit properly and last.

Scene 1
A roller is only as good as the bracket that holds it. The technician inspects every hinge for cracks at the knuckle, elongated holes and loose or missing fasteners, checks that the top fixtures still adjust and hold their setting, and looks over the bottom brackets for rust, deformation and the condition of the cable attachment. Jamb brackets and the flag brackets at the top of the vertical track are checked for movement. A door moves more than a thousand times a year and that vibration loosens bolts, so a hinge that has been working loose is often the reason a wheel wore crooked, and it is refastened or replaced as part of the same visit.
Scene 2
The top rollers sit in fixtures that slide in and out on the top section rather than in fixed hinges. The technician loosens the fixture, swaps the roller and then sets the fixture position with care, because that adjustment is what pushes the top section snug against the header seal when the door closes and keeps the wheel riding in the track rather than binding against it as the door starts to open. On heavy doors the top rollers do the most work of any on the door, so this is also where a higher load rating or a longer stem earns its place.
Scene 3
With smooth rollers under the door, the opener goes back to its intended job of guiding a balanced door rather than hauling a rough one. The technician will have confirmed the force settings and the reversal against a test block before leaving, and it is worth repeating the reversal check yourself each month: lay a 1-1/2 inch block, such as a scrap of two-by-four laid flat, in the door's path and close it; the door should reverse on contact. If the opener ever begins straining or reversing partway again, mention it at the next visit, since it is often the earliest sign of hardware wear.

No. The track is meant to be clean and dry so the wheels roll rather than slide. Grease or spray in the raceway collects dust, sand and, in winter, salt and slush, forming a paste that grinds the wheels and can let a roller skid instead of turn. The technician cleans the track and leaves it dry; at home, a wipe with a cloth and an occasional sweep of the bottom few inches is all the track wants.
A lubricant made for garage doors, applied lightly to hinge knuckles, roller stems and the springs, following the door maker's own recommendation, since the right product and whether bearings are included varies by manufacturer. General-purpose penetrating oils are thin and wash away, and heavy grease attracts grit. Nothing goes on the track raceway or on a nylon or plastic wheel. The opener's chain or screw rail may take a lithium grease according to its manual, and the manual for your door names what its maker prefers.
A heavier door needs rollers with a load rating to match, generally ball-bearing rollers rated around seventy-five to one hundred pounds each rather than the light plastic wheels many doors ship with. It often needs long-stem rollers at the double hinges on the end stiles, and the top rollers, which travel furthest under load, deserve the sturdiest in the set. Nylon with ten or more bearings suits most insulated residential doors; very heavy or commercial-weight doors may still call for steel.
