Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
Garage door opener doesn't open with wall button or remotes and light bulb does not come on. Unit clicks twice and LED light flashes 5 times.
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.

I've got a similar problem. The green light is flashing on the unit. I can here a click when I try either the remote or wall mount switch, but no movement.
FWIW our wall switch has a lock and a light switch and I can't get the light to go on either.
The door moves freely when disconnected from the opener.
My gut tells me the logic board is fried. What I'd really like to find is some sort of trouble shooting guide - Is anyone aware of any trouble shooting information on these lifts?

Same problem - The flashing wall button indicates the remotes are locked out. I fixed mine by pushing the green button on the back of the opener. I did nothing else , just left the LED time out.

first off, hitting extra button on remote would not do anything. Is door up or down/ where is trolley that attaches to chain, by door or motor. Is is jamned against a bolt. Try a paper clip and jump from white to read terminal. Does it work. Does light bulb blink 10 times. I ignore the diagnostic lights and go by symptons. Give more info.
