Garage Door Opener: Why is my garage door opener noisy?

If the garage door rattles or rumbles as it opens and closes, tighten any loose garage door opener hardware that connects the opener to the ceiling and attaches the opener rail above the door. Replace any broken garage door opener hardware that could allow excessive vibration. Check the alignment of the trolley on the garage door opener or the brackets; if you correct the alignment, tighten the hardware. Performing regular preventive maintenance on the garage door opener can also keep it running smoothly and quietly.

Worn gears inside the garage door opener's motor unit can make grinding or buzzing noises. Replace the gear and sprocket assembly or the drive and worm gears when they're worn and making noises. A worn belt or chain and cable assembly can also make noise-tighten chain or belt tension to correct this problem. Replace the belt if you can't adjust it to the proper tension because the belt is worn and stretched.
