Craftsman 1/2 HP Belt Drive Opener - Buzzing/Humming Sound

Posted by dcramse (My Page) on

Okay, my GDO works properly (in terms of closing and opening on demand w/ any of the remotes). The problem I am having is that it makes this constant buzzing/humming sound even when it's not in use. I thought it could be the light bulbs. However, the sound occurs w/ the lights on or off. The only way I've found to stop the buzzing is to unplug it (obviously). When I plug it back up, say after 5 minutes, the buzzing will come back after a couple of minutes. What's going on? Any help is definitely appreciated!!!! :)

Sounds like something vibrating. I would very carefully take off the cover and tighten every screw or nut I could find. Maybe even the cover vibrating. This is not a common complaint.
