Garage Door Opener: Why won't my garage door opener fully open or close the garage door?

When a garage door doesn't open or close all the way, first check the opener alignment and adjust if needed. A misaligned garage door opener may cause the door or trolley to bind up-causing the opener to stop or reverse because opening or closing force exceeded the opener's force limit. Watch this video for more details and garage door opener troubleshooting advice regarding force limits.

In some cases, inaccurate travel limits are the problem. Adjust the travel limit settings, following the instructions in your owner's manual. If you can't adjust the travel limits, you may need to replace the travel limit switches or the logic board.

This Sears garage door opener troubleshooting advice for resolving travel problems works for Craftsman, LiftMaster, Chamberlain and Genie garage door openers.
