SOURCE: 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.

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.

SOURCE: Craftsman Garage Opener Clicks only and LED blinking 5 times

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.

Garage door only opens sometimes with remotes< and exterior keypad. always works with wall mount button.


Check the light bulbs in the opener. Newer fluorescent or LED bulbs can generate enough radio frequency interference that the normal signal levels from the remote will be inadequate.
Of course, make sure the remote batteries are fresh.

It could be the garage door motor that is acting up. Try closing it with the button in the garage. If that's not the case, you may need a different garage door opener.

How do I program a remote garage door opener for a Crafstman 139.53615SR?


Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Hold down the button on the remote while you press and release the smart/learn button. If everything is working and it is the right remote for the opener it will be programmed.

Remote works only when Garage Door Opener light is OFF


I discovered that certain light bulbs interfere with the remote sensors. Harware stores have clear vibration reisistant bulbs for garage doors, try them instead. After spending money on a new remote, resetting remotes, and weeks of aggravation...poof.....i found it was the type of bulb I was using. Used a clear bulb and the problem went away. Hope this helps.
