Mastercraft 3/4 hp garage opener problem

Hi all!

I have a 3 year old MasterCraft 3/4 HP garage door opener that suddenly started giving me trouble...It happens from both remotes and wall panel...About 75% of the time the door wont close..I hear the motor power up but the door moves only a few inches then it goes back up lights blink 3 time ...and the learn indicator blinks 4 times... Does anyone know the error that the learn indicator blinking 4 times is related to?

Thanks for your time everyone! :)
