garage door opener rattles and opens only slightly - seems to be stuck
by Manage My Life Last activity date:
my garage door opener (sears 139.53975SRT1) 1/2HP just started vibrating as it opens. it tries to open then gets stuck at about 10" off the ground and stays rattling until I press the open/close button on the remote again. It does this regardless of which remote I use (wireless, or the main pannel).
when I release the handle, the chain moves freely all the way to the close/open position. I tried adjusting the up force but it didn't help.
Any ideas as to what the problem is would be appreciated.

Release the door from the opener and run the door by hand. Check for the balance of the door and ease of operation paying attention to all moving parts. A good running opener can't run a bad running door. If all is good in the door then more than likely the main drive gear has begun to strip. Unplug the unit and take off the motor housing. Look for white grit on it and look at the large star gear for wear, If that is not it look at the top of the opener at the drive sprocket for wear or damage. If you need parts go to searspartsdirect.com. Thanks BB
