Unable to close Garage door with remote
If you watch the back of the opener starting at around :54 in the video, you'll notice that the LED indicator flashes 4 times.  For Craftsman openers, this is almost always the code for an issue with the interrupt sensors.  Make sure that they are clean and getting power (no wire breaks, etc.), and then follow the instructions in the owners manual for aligning them.  If you don't have a copy of the manual, get the model number off of the opener and check to see if they have a .pdf at the manufacturer's website (www.searspartsdirect.com).
