The remote opener reset button goes off and will not work

There is a green reset button o the back of the unit and the green light has to be on in order for the remote to work. Once I reset the green button the green light comes on but will go off after about one minute. When the green light is off, the remote wouldn't work Works with the wired switch even if the light is off.

The green button is not a reset it is the program button.

If you hold the button down for about 20 seconds it will erase all codes. Then, press and release the button - press and hold the button on your remote for about 10 seconds. the next time you press it it should activate the door. Repeat the 2nd step for all additional remotes.

The lock button on the wall control locks out all radio signals for vacations etc.

If the lock has been activated the green led in the wall control will flash - when the lock is deactivated the led stays solid green.

Hope this helps

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.
