Mine has just recently started doing the exact same thing. I can close it from the wall unit if I hold the button down until it closes completely or else it goes back up. The strange thing is that it just happens. The same with it working again. It just starts. My wife left for work this morning and it didn't work. I messed with it some and no luck. I came down to see if I could get some info online and went up to get some information off the unit and now the door is working again. I just bought this house so don't have any manual for it.
