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

Opener keeps losing code

I have a Sears/Craftsman 1/2 HP garage door opener that is approximately 15 years old (guessing it was installed when home was built in 1994). Lately, I have to constantly reset the transmitter. I know the code has been lost when I see the lighted button on the wall beginning to rapidly flash. It is no big deal to conduct a re-set, but I'm having to do this 4-5 times a week. Can you tell me what is causing this and if there is a solution outside of installing a new opener? Thanks for your help in advance.

YOU MAY HAVE A LOOSE BATTERY CONECTION IN YOUR REMOTE.

ANYTIME THE BATTERY CONNECTION IS LOST (EVEN MOMENTARILY) YOU WILL NEED TO REPROGRAM IT.

IF YOU CAN'T FIND AN OBVIOUS PROBLEM WITH THE BATTERY, I WOULD REPLACE THE REMOTE.

HOPE THIS HELPS

My garage door will only close when I push and hold the button. I'm assumung it's the safety reverse sensors. I have 1 LED lit on the one sensor but the other side is out. Do both have to be lit to...

Yep.
Just had the same problem. I'm guessing years of salt and cold took out the one side. I live in St Paul.
I had to order a new set on ebay. I was surprised since the opener is 15 years old, but they had a few to pick from.
But installed and everything is fine now.

Replaced door sensors now door will not go down and light flashes

The safety eyes are either installed wrong, or you have the wrong type. Craftsman (liftmaster) has what they they call old style and new style safety eyes. You can not interchange the types.
