By robert korpella vibration is the cause of most noise problems associated with garage door openers.
Garage door sprocket noise.
A constant grinding noise could be a sign that your garage door opener s chain or belt is either too loose or too tight either way it needs adjusting.
Start with a visual inspection of the sections panels looking for any signs of dents bending creases or cracks in each panel.
Over time the sprocket s teeth can wear and the chain may jump or skip when the opener raises the door.
If you have a track drive opener the next step is to lubricate the opener track with grease.
As the drive shaft and sprocket rotate they drive the trolley that lifts and lowers the garage door.
The plastic gear on the drive shaft is designed to fail if the garage door gets stuck in the travel tracks protecting the expensive drive motor from damage.
A loose garage door opener chain makes loud slapping sounds and causes jerky door movements that smack the rollers against the track.
If your garage door is making lots of noise during use you need to perform a visual inspection of all of the components in your garage door system.
