No. Tracks should be clean and dry. Rollers are meant to roll along the track on their own bearings, and a film of lubricant on the track collects grit, thickens in the cold and makes the rollers slide and drag instead. Wipe the tracks with a rag and put the lubricant where it belongs: on the hinge pins, the roller bearings, the spring coils and the bearing plates at the ends of the torsion shaft.

Usually the standard two-inch track handles a residential insulated door well, provided the gauge matches what the door maker specified and the brackets and hangers are properly fixed. Very heavy or oversized doors, and some carriage-style wood doors, are set up on three-inch track or on heavier-gauge two-inch. If a heavier door was hung on the light track from an earlier door, flexing and spreading follow, and the technician will say so.

Cold makes steel slightly less forgiving and thickens the grease on the coils, so a spring that has already used most of its cycle life is more likely to let go on a frosty morning when the door is first opened. The cold is the final straw rather than the cause; the underlying reason is fatigue from years of cycles, sometimes helped along by rust and dry coils.

Springs are rated in cycles, one cycle being a full open and close, and a standard set is built for a number in the ten-thousand range. A door used four times a day gets through that in several years; a door used a few times a week takes far longer. An unheated, damp garage shortens the figure through rust. Regular lubrication and a door kept in balance stretch it out.
