Before you consider to fix a garage door, examine the rollers and tracks on the garage door. If you can’t remember the last time you cleaned them, now is the time to clean the rollers and tracks with a good brushing and to lubricate the rollers and axles. The bearings on rollers can also wear out; replace any rollers that don’t operate smoothly.

Tighten the hardware. The tracks that guide the rollers on an overhead garage door are assembled in sections and attached to the garage with brackets. Makes sure the sections are well secured and that the screws and bolts that hold the brackets are tight.
