A bad start cap will make the motor hum and not turn. Replace that first as it is fairly inexpensive. If it still does it, it is the motor or gear box. At that point it would probably be best just to buy a new opener as a motor or gear box will be rather expensive.

It could be a couple of different things. The motor might be having some issues, the gears could be slipping, the chains might not be on track...I would have it checked out. There is a good possibility that you can simply replace one or two parts without having to replace the entire unit, which can save you a lot of money in the long run. But the only way to know for sure is to have someone come out and troubleshoot the unit. It could just be dirty and just need to be cleaned.
