Chamberlain — Won't Close (Reverses Immediately)
When a Chamberlain garage door opener reverses immediately after hitting close, it's almost always a safety sensor issue. The two infrared sensors at the bottom of the door tracks need a clear line of sight to each other. If anything blocks them, is misaligned, or the lens is dirty, the door won't close.

LiftMaster — Remote Not Working
When a LiftMaster remote stops working but the wall button still operates the door, the problem is almost always the remote — not the opener. A dead battery is the cause about 60% of the time. If it's not the battery, the remote may have lost its programming and needs to be re-paired.
