Most of the emergency calls we run were preventable, and the prevention takes about fifteen minutes twice a year. Spring and fall are the natural times — before the heat and before the freeze.
Run the door through a full cycle and just listen. Grinding, popping, and scraping each mean different things — and a door that changed its sound in the last month is telling you something.
This is the single most useful check on the list. Close the door, pull the red release cord, and lift the door by hand to about waist height. A balanced door stays roughly where you put it. If it drops or shoots up, spring tension is off — that's a technician job, not a DIY adjustment, but knowing now beats discovering it when the spring snaps.
Use a garage-door-specific silicone or lithium spray on hinges, roller bearings, springs, and the opener rail. Skip WD-40 — it's a solvent, not a lubricant, and it strips what's already there. And never grease the track itself; the rollers are meant to roll along it, not slide.
Springs, cables, and the bottom brackets they attach to are all under high tension. Inspect them, note anything wrong, and let a technician do the work.
