Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
The motor engages for a split second, then stops. I unhooked the door from the chain drive, and it's acts the same. If I keep pressing the wall switch, it just clicks for a split second and stops...once in forward and once in reverse. This same thing happened a few months ago, then started working normally again. Any thoughts on what could be wrong?
If motor continues to run but no chain action check for missing chain tooth or cam gear worn.

If you can press and hold the wall button and the door will go down, you have a photo eye issue. Check the photo eyes at the bottom of the door.

Check the down limit:
If the light bulb(s) on your operator are on the front and/or back, the limit adjustment screw is on the left side of the operator (looking from the back of the operator and facing the garage door).. If the lights are on the sides of the operator then the limit adjustment screw is on the left side (looking from the back of the operator and facing the garage door).
Check the up and down force:
On your operator (the box that hangs from the ceiling). If the light bulb(s) on your operator are on the front and/or back, the force adjustment screw is on the back of the operator. If the lights are on the sides of the operator then the force adjustment screw is on the right side (looking from the back of the operator and facing the garage door). Turn the light blue adjustment screw with the up arrow to a higher number.

Well sounds like its a pressure setting. you said you open the door by hand? Was it easy to do? Ask your self this can a 15 year old kid open it and close it? If so then it sounds like its a presure setting There should be two blue slots on your opener with numbers 1-9 says up and down force. Turn the up force towards the bigger number. Just a little bit. But before you do that as the other guy stated make sure that your cables and springs are working. Spring depending on your doors can be in three places but we going to assume you has the most common set up so look over the top of your door (with it closed) you should eb able to see a tube running across there. and somewhere in the in middle a set of spring look at the spring to make sure that you dont see any of the tube showing in the springs. Becare not to touch the spring as they are under a lot of stress.

The only procedure I have ever followed is to press the learn button and then enter the code, and not do anything else. I think your last step of holding the button until the light goes out is clearing codes as fast as you enter them. Just stop after you enter your code and let the learn mode time out on its own. That should do it.
And don't put your head through the wall. It just causes more headaches.
