Most garage door repairs are preventable with basic seasonal maintenance. A few minutes twice a year can meaningfully extend the life of springs, rollers, and the opener motor.
Twice-yearly checklist
Lubricate moving parts. Use a silicone- or lithium-based lubricant (not WD-40, which attracts dust) on rollers, hinges, and the track.
Test the balance. Disconnect the opener and lift the door halfway by hand - it should stay in place. If it drops or shoots up, the springs need professional adjustment.
Inspect cables and springs visually. Look for fraying, rust, or gaps in spring coils. Don’t attempt to adjust these yourself.
Check the auto-reverse safety feature. Place a block of wood in the door’s path while closing - it should reverse on contact. Also verify the photo-eye sensors reverse the door when the beam is blocked.
Tighten hardware. Track brackets and roller brackets loosen with regular use - a quick pass with a wrench keeps things aligned.
Clean the tracks. Wipe debris and old grease buildup out of the tracks so rollers move freely.
When to call a professional
If you notice uneven movement, unusual noises, or visible wear on springs and cables during a maintenance check, it’s worth having a technician inspect before it becomes an emergency repair.
