Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

1 Answer

Door won't close, with out hold down on button.

Starts to close, then comes back up. Green light on control, and light on
motor flash. If you hold down button on wall control, or either remote it will close all the way. The door returns to open without a problem. I have checked for any think breaking the safety light, and found nothing.

If the main light flashes 10 times when the door reverses it is a door sensor problem. Make sure they are pointed at one another and the small light on each one is lit and not blinking.

If the main light is flashing 10 times when you try to close the door it is a door sensor problem. Make sure the small light on each one is lit, not flickering and that one is not dimmer than the other. Tweak them a bit if necessary.

It sounds like you have a problem with your wall button. I would remove the button from the wall and then disconnect the 2 wires on the back. Remember where they go as they are color coded. You can then momentarily touch the two wires together to check the operation. There isn't enough voltage there to bother you.

One thing to remember. If when the door reverses the main light flashes 10 times it is a door sensor problem and nothing else.

Garage Door Wont Close Craftsman 1/2 HP (1998)


What it is is the electric beams at the door are getting blinded buy the sun or out of line. They are the two black boxes on both sides of the door about a foot from the ground. Put a piece of card board in front of them not blocking the beam dut to block the sun. All that they are is safety beams for kids so they do not get hurt. If you have to move them to the top where the sun will not hit them. Sorry to say though you can not remove them all the way. Also make sure the lite on them is not blinking if so they are out of line.

Good Luck and Please Rate FixYa!

Pressing remotes the door won't go u[


It sounds like you have the lock enguaged. When it is flashing it locks out all remote access. Hold the lock button for 3 seconds. The green light should go solid. On the issue of closing, it is most likely a safety eye issue. Hold down the wall button. If it closes it is the safety eyes. Holding the button overrides the safety eyes. Make sure that thelight on both eyes are both lit.

The remote opener reset button goes off and will not work


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
