In this video I have a LiftMaster side mount that just won't work. It's a model LJ8900W. These garage door openers are super reliable for the most part. But this one was a little different. After going through troubleshooting with LiftMaster it ended up being a bad logic board. Replacing it was easy!
Check out the video on how to do it. Thanks!
