From Chamberlain's website:

There are a few different things that can cause this type of problem.
  1. Look at the LED light next to the SMART/LEARN button on the motor unit. If you are facing the garage door, the SMART/LEARN button is located on the rear end or right hand side panel of the motor unit. You may need to remove a light lens cover in order to see it. This button is either purple, red/orange, green, yellow, grey, or white in color. If the light is flashing rapidly this means you have a stuck button on one of your remote controls. Take the batteries out of each remote control. When you remove the batteries from the bad remote, the light will stop flashing. This remote needs to be replaced.
  2. If one of your neighbor's remote controls is inadvertently programmed into your receiver, your door will open when their remote is activated. If this happens you will need to clear out your receiver and reprogram your remote controls:
    1. Press and hold the LEARN button for six seconds, or until you see the small LED light near the button turn itself off.
    2. If the above steps have been followed and the symptoms continue, there may be an electronic short in either the wall control button or the receiver logic board. In this case, remove the wall control wires from terminals one and two (or red and white) on the motor unit. Should the symptoms persist after the wires are removed, replace the receiver logic board. If the symptoms stop with the wall control wires removed from the motor unit, replace the wall control button, and the wires leading to the wall control button.

Pull the logic board and check it for burnt or missing traces on the printed circuit. Thunderstorms love logic boards.

Remove the bulb and try. The bulb or the socket may be radiating a signal. Unplug the opener and pull out on the center contact of the light socket. Try another bulb.

mikey-moore's advice helped me figure out what to do but it's not exactly what I had to do. Manually open the garage door all the way. Then hit the automatic button you normally would use to open and close your garage door. The bracket slides back and locks into place. Hit the automatic button again and the garage door should automatically close.

Try unplugging the opener and removing the bulb. Now pull out on the center contact in the light socket.

Did you inadvertantly hit the "vacation lock" button on the Mounted push button? This will cause the remotes not to work. Try hitting the button again, and then see if the blinking goes to solid green.

Good Luck

the craftman george door opener will not close the light blinks five time. what is that?

Sears Craftsman... | Answered on Jul 17, 2018

There hasn't been a manual for that opener for over 20 years. Sounds like you have a door problem if it won't stay up.

Sears Craftsman... | Answered on Jul 12, 2018

If you can not open the door sounds like you might have a broken spring. Call a professional do not try to repair the spring yourself.

simple , i was a sears installer for 10 years installing garage door openers so your in luck , just locate the smart button on the machine ,it would be on the back or if your looking from the back at the back ,it could also be on the right side depending on if the machine is a sideways mounted machine or frontmount, after locating this button which maybe green/orange /or purple in color also depending on your model ,the newest sears machines are purple buttons ,and 5 years ago they were orange and the older ones would be green ,...ok so after you,ve located it just push it once and you will see a solid yellow indicator light come on , now go over to the keypad and put your 4 digit personal code in after that press the enter button AND HOLD IT for around 3 seconds , at that time you will see the lightbulbs on the machine go off and then click back on , and THAT,S IT! plain and simple , now go proramm your remote! hope i was of help to you , and if i was leave me a nice rating Sincerely Glenn mayer
