Opener stuck in "lock" position

Garage door opener shows "unlocked" - no blinking lights, however, it only operates from inside the door. The remote openers and the keypad outside are not working. Any suggestions?

Liftmaster security + remotes do not operate. I bought 2 new remotes and neither one of them will program to operate the opener either.


Yes it sounds like the board. Make sure the opener is not in lock. If the light in the wall control is blinking press and hold the lock button for 3 seconds.

I have a 1/2 hp craftsman opener. Remotes work fine. Wired wall unit has a blinking light on the open button and will not work Lock pad and light pad work but not the operate pad.????


Try pressing and holding the lock button for 3 seconds to stop the light from blinking. Your wall control may be bad. Usually when that light is blinking it is the remotes that will not work.

Door operates ok with indide panel but not remotes


Two possibilities right off the bat. One is the opener is in vacation mode. You can tell if this is the case by the rapid blinking of the light in the wall control. If this is the case press and hold the button with the lock icon for 3 seconds.

If not the case you have a bad logic board.

Remote not working


you will need to train (link) the remote to the garage door opener. to do this you will need to find the remote "train" button on the operator.
If you have the manual for the garge door opener this will show you where it is located.
push the train button on the operator, an LED light will start blinking. Then push one of the buttons on the remote. the LED light on the operator will stay on. push the button on the remote again and the light on the operator will turn off.
try the remote it should work now.

Door opens on it own and light blinks


  • Stuck remote control button. Check all remotes. check LED on receiver.
  • Staples around Multi-Function Control Panel bell wire could be cutting into that wire. Remove wires from opener and test. Replace staples causing intermittent short.
  • Multi-Function Control Panel could have sticking door control push bar. Remove wires from control panel and test. Replace control panel if defective.
