I have a Genie garage door opener (belt drive) about 2 years old. It gets stuck quite often. It doesn't operate from remote or wall switch. Only way I can make it work is first disconnect the latch (door). Than either open or close (depending where it is stuck) the door manually. After that realeas the latch and push the remote control. The slider moves and engages the door and then it would operate. This happens almost every other day.
Everything check out fine. The sensor and limit switches seems to be working fine. Will greatly appreciate any clue. Thanks.
