Craftsman Garage door opener

Several symptoms-
1) Doesn't open from remote (sometimes)
2) Will try to close but will stop 1/4 down and then go back up.
3) Will only close 100% when holding down button from inside the
garage.

The sensors (as mentioned in previous posts) are good candidates. My
opener has a resistance setting where it reverses if too much resistance
is encountered. Perhaps your opener has a similar setting and you can
just tweak it to increase the limit? Of course, your door might be
encountering more physical resistance due to a vehicle impact or some
other recent change (in that case increasing the limit may not be wise,
at least not long term).
