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

2 Answers

CHAMBERLAIN WILL NOT RESPOND TO REMOTES FROM STREET.

I HAVE A CHAMBERLAIN OPENER ON ONE DOOR. A FRIEND GAVE ME HIS OLD CRAFTSMAN OPENER. I INSTALLED IT ON MY OTHER DOOR. NOW MY CHAMBERLAIN DOES'T OPEN WITH THE REMOTE UNLESS IT'S REALLY CLOSE TO THE OPENER. I UNPLUG THE CRAFTSMAN AND IT WORKS FINE. WHAT CAN I DO, OTHER THAN TAKING OUT THE CRAFTSMAN ?

Sounds like "cross talk" interfence from the other operator. You can get a plugin external reciever that should work with your current remotes. Try to get as much distance as you can between the working operator and the new reciever.

You must have an older vehicle or the homelink has reverted to an earlier technology and you will have exactly the situation you describe. You will just have to use the remotes that came with the opener.

The precise remote issue


Try holding down the wall button. If this does work the door as you hold it down then the problem is misaligned sensors. If it is not that then more than likely the logic board is not good. I have never seen a whisper drive that has a door bell button and only came with one remote though???Thanks BB

Craftsman keypad not responding


On the back of the motor unit near where all those white wires go you will find a button. Press and immediately release that and then walk over to your keypad and enter a four digit code of your choice and press enter. You should be good to go.
