A garage door maintenance checklist built for Michigan winters
Updated 2026-03-05 MaintenanceSeasonalChecklist
Michigan is unusually hard on garage doors. Road salt corrodes cables, sub-zero mornings thicken the grease in roller bearings, and the freeze-thaw cycle bonds the bottom seal to the slab so the opener tears at it every morning. Twenty minutes twice a year prevents most of the failures we get called to.
The balance test (do this first, every time)
Everything else depends on it. Pull the red release cord to disconnect the opener. Lift the door by hand to about waist height and let go.
- Stays put: springs are correctly tensioned. Good.
- Drops: springs are weak or undersized. The opener is carrying weight it was never designed for.
- Rises: springs are overwound. The door can fly open and the top section takes the strain.
A door failing this test will destroy an opener within a year or two. It is not a cosmetic issue.
The safety reversal test
Two separate systems, both worth checking.
- Photo eyes: with the door closing, wave a broom through the beam near the floor. The door must stop and reverse immediately.
- Contact reversal: lay a flat 2x4 on the floor in the door's path and close it. On contact the door must reverse, not push.
If either fails, the opener's force settings need adjusting or the sensors need realigning. Do not disable the sensors as a workaround; they are the reason garage doors stopped killing children.
Cables and drums
Look along both lift cables from the bottom bracket up to the drum. You are looking for rust, kinks, flattened sections and broken strands sticking out like whiskers. In Michigan the corrosion almost always starts at the bottom, where salt-laden slush sits against the bracket. A cable with broken strands is weeks from snapping. Do not touch the bottom brackets yourself, they are under full spring tension.
Rollers and hinges
Spin each roller by hand with the door disconnected. It should turn freely and quietly. Flat spots, wobble on the stem or a bearing you can feel grinding means replacement. Check hinge plates for cracks around the pin hole and for screws backing out of the panel.
Lubrication, done right
| Part | Product | Frequency |
|---|---|---|
| Hinges & roller stems | Lithium or silicone garage door lube | Twice a year |
| Torsion bar end bearings | Lithium spray | Twice a year |
| Opener rail (chain/screw) | Manufacturer-specified grease | Once a year |
| Springs | Light coat only | Once a year |
| Track interior | Nothing. Wipe clean only | Twice a year |
Avoid WD-40 for lubrication. It is a solvent that strips existing grease and evaporates, leaving the part drier than it started.
The bottom seal
This is the Michigan-specific one. Check the rubber astragal along the bottom of the door for splits, hardening and gaps you can see daylight through. A failed seal lets meltwater under the door, which then refreezes and glues the door to the slab overnight. The opener then either strains against it or reverses and reports an obstruction. Replacing a bottom seal in autumn is cheap; replacing an opener in February is not.
Seasonal timing
- Autumn (best time): full checklist, plus bottom seal replacement and a switch to a cold-tolerant lubricant.
- Spring: wash salt residue off the track, brackets and cable ends, then re-lubricate and repeat the balance test.
- Any time you notice: new noise, slower travel, uneven movement or the opener working harder than it used to.
What to leave to a technician
Anything involving springs, cables, bottom brackets or the drums. These carry the door's full stored energy. Everything else on this list is safely within reach of a careful homeowner with a socket set. If you would rather have it all done and documented, our annual tune-up covers every item above.
