    I have the same problem. Door opener won't function going up or down. Just the breif buzzing sound. There is one difference though - where you say the green light, mine is yellow...



    Anyone have ideas?



    Thank you,

Check to see if the traveler is against the bolt on the rail.

If it is, you need to loosen the chain and adjust the up limit to keep it from reaching the bolt.

When hitting start button, it sometimes buzzes, but fails to start. Can sometimes wait for a little while and try again, and it starts. When it buzzes, it will only buzz for a few seconds and then nothing.


it is either the door switch or start switch, this website will show you how to test both, Good Luck Tim:

seems like the door safety switch is stuck. open door and look for it, a little dowel, see if it is clicking on and off. to test, open door, let the drier buzz and try pushing the little switch in and out.

Craftsman Garage door opener not working


First, check the springs in the actual door to make sure that they are not broke. Since you held the learn button down to reset the opener, you have to reprogram all of your remotes. This button only resets the remotes. It has nothing to do with the rest of the opener. To reset the opener, simply unplug it for a couple of minutes and then plug back in. Pull the handle on the door and see if you can operate the door manually with one hand. If it takes more than 15lbs to move the door, there is a problem with the door balance. If the springs are not broke and the door operates smoothly, the likely cause is the rpm sensor on the opener.

Garage door remote won't open the garage door


The little button with a padlock on the wall control is a "vacation" lockout feature that disables the remotes. There should be a small LED on the wall control that is always on steady. When the padlock button is pressed and released the LED should be constantly blinking (indicating the vacation lockout mode is active) and your remotes should be disabled. The wall control will still operate the door. Pushing the padlock button again should make the LED stop blinking and restore the door to normal operation.
