Garage doors are the largest moving systems in most homes. Use the checks below only when the area is stable and safe. Do not touch springs, cables, drums, or a crooked door.
Watch and listen once a month
Stand inside the garage and operate the door. Watch for shaking, uneven movement, hesitation, and scraping. Listen for new popping, grinding, or rattling sounds. A change in normal operation is often the earliest warning.
Inspect without touching tension parts
From a safe distance, look for frayed cables, gaps in springs, bent tracks, loose-looking hinges, damaged panels, and worn rollers. Do not tighten, unwind, or remove spring or cable hardware.
Test the photo-eye reversal
With the door open, place an object in the beam path and press close. The door should not close while the beam is interrupted. If it moves downward, stop using the automatic opener and arrange service.
Know when maintenance becomes repair
Lubrication and visual checks cannot correct a broken, bent, or unbalanced system. Schedule an inspection when operation changes, safety tests fail, or wear is visible. Early attention can help prevent damage to connected parts.
