1/2 hp Craftsman Garage Door Opener, desparately need help!

I have a 1/2hp model 139.53973SRT which has been acting very quirky.

Here's what it was been doing (very inconsistent and has now stopped giving problems since this happened a week ago)

-it started that a few times on it's own it opened a few seconds after it closed with no blinking lights

-when going halfway down, it came back up and started blinking as if something was tripping the floor sensors, nothing was

- it then went down and stopped halfway, not blinking, but then when I pressed the wall control it wouldn't move up or down, no lights were blinking and all I would here is a click of sorts when I pushed the button.

I then disconnected the safety to close the door manually, when I reattached it the following day it works fine since, but a little yellow light by the "smart button" keep blinking.

Does anyone know what that light might mean and what could explain the irratic behavior?

Thanks so much in advance!
