The full yearly DIY tune-up. Print it, work through it in order, mark it done. Most steps take a minute or two. The two safety tests at the end are the ones homeowners usually skip — and the ones that matter most.
Everything fits in a small toolbox. If you don't have these on hand, that's reason enough to set the reminder a week ahead — that's the lead time to grab the right lubricant instead of using whatever's in the garage.
In order. Each step builds on what the last one revealed.
Run the door through one full cycle while standing inside the garage. Watch for jerking, sagging, uneven movement. Listen for grinding, squealing, popping. Any sound that wasn't there a year ago tells you which area to pay extra attention to in the next steps.
1,500 cycles a year vibrates fasteners loose. Go through every bolt, hinge bracket, and track bracket with the wrench. Hand-tight is enough — don't strip the wood or metal. Pay extra attention to the brackets connecting the tracks to the wall and ceiling.
Wipe the inside of the tracks with a rag — dirt, leaves, dead bugs, lubricant buildup. Tracks themselves should be clean and dry, never lubricated. The rollers ride in the tracks, and lubrication on the track itself just collects more grit.
Hinges, roller stems (not the wheels themselves if they're nylon — wipe them clean instead), springs, the bearing plates, and the opener rail. A short spray on each, then run the door through one cycle to spread it. Don't over-apply; lubricant catches dust.
The rubber strip along the bottom and sides keeps weather, leaves, and pests out. If it's cracked, hardened, or pulling away, replace it — bottom seals are sold by the foot at any hardware store. A failed bottom seal is a sign that water has been pooling at the base of the door, which corrodes the bottom panel.
Pull the red emergency release cord to disengage the opener. Manually lift the door halfway and let go. A balanced door holds its position. If it falls, the spring is weak. If it shoots up, the spring is overtensioned. Either way, call a pro — never adjust torsion springs yourself. Re-engage the opener after.
Place the 2x4 flat on the ground in the door's path. Close the door with the opener. It should hit the wood, reverse, and reopen within 2 seconds. If it doesn't, the auto-reverse force setting is wrong or the opener has a fault — either way, don't use the door until it's fixed. This is the only test that protects pets and small children.
The two sensors near the floor send an invisible beam between them. Close the door with the opener and wave a broom through the beam. The door should immediately reverse. If the sensors are misaligned (one LED blinking instead of both solid), adjust them by hand until both LEDs are solid green or amber, then re-test.
Three things get a pro every time. They store enough mechanical energy to seriously injure you.
Everything else on the checklist is safe for a homeowner with a stepladder.
A printed checklist on the workbench helps zero if the year goes by without you ever looking at it. The reminder is the trigger — an email a week ahead, then on the day, then follow-ups until you mark it done. That's the missing piece between "I should do this" and the door actually getting serviced.
See the broader garage door maintenance reminder guide, or check how often to service a garage door to confirm yearly is right for your usage and climate.
Set the trigger now — get the email a week before service day.
Done in seconds. No sign-up required.
Around 30 minutes for the full 8-step yearly checklist if you have your supplies ready: silicone or lithium spray, a socket set, a stepladder, and a clean rag. Most steps are 1–3 minutes. The balance test and auto-reverse test take the longest because each requires running the door through a full open-close cycle.
Visual inspection, hardware tightening, track cleaning, lubrication, weatherstripping check, balance test, auto-reverse safety test, and photo-eye alignment. That's the full annual checklist. Lubrication should be done more often than the rest — every 3–6 months — but everything else fits into a once-a-year session.
Broken torsion springs, by a wide margin. Springs are rated for roughly 10,000 cycles, and unlubricated springs reach end-of-life faster. The next most common problems are misaligned photo-eyes (the door reverses or won't close), worn rollers (grinding or shaking), and frayed cables. All four are catchable in a yearly inspection.
Pull the red emergency release cord to disengage the opener, then manually lift the door halfway and let go. A properly balanced door stays roughly halfway open on its own. If it slams down or shoots up, the spring tension is off and a pro needs to adjust it. Do not try to adjust torsion springs yourself — they store enough energy to cause serious injury.
Place a 2x4 flat on the ground in the door's path, then close the door with the opener. The door should hit the wood, reverse, and reopen within 2 seconds. If it doesn't, the auto-reverse is failing and the opener needs adjustment or replacement. Federal law has required this safety feature on residential openers since 1993.
No. WD-40 is a solvent and degreaser, not a lubricant — it strips away the lubrication you actually need. Use silicone spray or white lithium grease instead. The misconception is so common that several manufacturers print "do not use WD-40" directly on the spring or roller hardware.
Free, no account. You'll get an email a week before — long enough to grab the right lubricant and clear an afternoon.
