20 Most Recent Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+ Questions & Answers


I have a sears model

Your opener is very old and I'm positive you can no longer get the remotes. You might look into one of these.

Craftsman - Model #00953751000

It is a universal remote and receiver that operates on the new frequency and has the rolling code feature.

Sears garage door opener

I just found the solution for my 'ancient' Sears garage door opener, model # 139.655000, and I figured I'd share it.

There's a separate radio module, wired to the main opener. This module is small, has a short wire/antenna, and plugs directly into an outlet.

There's a manual open/close button on this module (I didn't realize this until I got up on a ladder). This button is also a removable cover; underneath it is a "smart actuate" button -- this is your learn button.

What I did was: unplug the radio module. Pry off the cover. Plug the radio module back in. Hold down the button on the remote. Press the "smart actuate" button. This programmed my remote successfully!

This is a very unusual problem you have. The only thing I can think of is trying a different light bulb or try unplugging the opener and removing the light bulb. Pull out slightly on the center contact of the socket. I am thinking some arcing is causing this problem.

I have a craftsman garage opener and my lock won't work

The wireless keypad should work but the remotes should not. I suspect a bad wall control but there is a possibility of a bad logic board. If you have a neighbor with a 3 button wall control see if they will let you borrow it to eliminate that problem. Just make sure you note which wire goes where on the back of the control. They are color coded.

The button should be on the back of the motor unit. You may have to remove a light lens to find it.

Light does not come on when I open/close door, not the bulb

Good Morning:

I also substituted Floescent Bulbs for the standard bulbs. The bulbs would not light up although the relay was working. It seemed that the Florescent bulbs had a somewhat shorter neck. What I did was unplug the drive system from the outlet and then bend the metal connector in the socket so that it would come out further towards the opening of the socket. I then repluged the drive. The Floercent bulbs now have contact and are working perfectly. Simple problem with a simple solution.

This is the most difficult question to answer because technologies and frequencies have changed and there is not a good way to check. If you program the opener to this remote and your other remotes quit working or if it will not program at all then you know the answer.

Cannot find compatable keyless entry

The keypad listed for your model is 53876. If this is the keypad you presently have and the remote no longer works after you program the keypad it could be the remote that is bad. Sounds strange but it is true. Make sure you are programming the keypad like this.

Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to the keypad and key in any 4 digit code you like and press enter.

Light will not come on when you walk into the

To have your lights come on automatically when you walk into an open garage you must START with the lights ON. To turn the feature on, turn the lights on manually with the wall switch, then press and hold the LIGHT button for about 10 seconds until the motor unit light bulbs flash.

Now, if the light bulbs are on, manually turn them out and then walk out through the open door. The light bulbs should come on.

To disable this feature, start with the light bulbs OFF and everything else is the same.

Liftmaster garage door intermittent power loss

I had the same problem. Although it appeared to be the logic board, on mine it actually was the connectors between the logic board and the power supply board.
There are 2 connections on the logic board. One white connector with wires going to the main unit, and another set of connectors that plug directly into the smaller circuit board that holds the step-down transformer (120vac - 22vac). These pins were not making good connection between the boards. I simply bent the pins slightly so they would make better contact on the logic board and have not had a problem since. This must be a weak point on these door openers. Purchasing a new logic board would work too, as the connectors are newer and tighter.

Garage door opens by itself

From Chamberlain's website:

There are a few different things that can cause this type of problem.
  1. Look at the LED light next to the SMART/LEARN button on the motor unit. If you are facing the garage door, the SMART/LEARN button is located on the rear end or right hand side panel of the motor unit. You may need to remove a light lens cover in order to see it. This button is either purple, red/orange, green, yellow, grey, or white in color. If the light is flashing rapidly this means you have a stuck button on one of your remote controls. Take the batteries out of each remote control. When you remove the batteries from the bad remote, the light will stop flashing. This remote needs to be replaced.
  2. If one of your neighbor's remote controls is inadvertently programmed into your receiver, your door will open when their remote is activated. If this happens you will need to clear out your receiver and reprogram your remote controls:
    1. Press and hold the LEARN button for six seconds, or until you see the small LED light near the button turn itself off.
    2. If the above steps have been followed and the symptoms continue, there may be an electronic short in either the wall control button or the receiver logic board. In this case, remove the wall control wires from terminals one and two (or red and white) on the motor unit. Should the symptoms persist after the wires are removed, replace the receiver logic board. If the symptoms stop with the wall control wires removed from the motor unit, replace the wall control button, and the wires leading to the wall control button.
