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

1 Answer

Do I need to replace everything, if I buy a new garage door open.

I currently have a 10 year old 1/2hp craftmans garage door opener and I think it may be best if I replace it. What parts or assembly can I leave in place when I am setting up my new unit?

My 15 year old system broke down due to a worn screw drive. While parts like this can be replaced, it takes a bit of guts to work inside the motor, and the circuit board. I chose to buy a new unit. New units come with all the parts ... so you don't really save much, Depending on how old the system is, the old accessories may or may not work. Even though my old 1/2 H.P. motor was a chain drive, when I bought a new screw drive the mounting parts on the ceiling and on the wall above the door were compatable. So while you get the new parts in the box, you can use the old parts if it saves you time. I was not able to save the electic eye components as the number of wire leads was slightly different in the new model. It took me and my son about 2 hours to get the old one down and the new on up. Hope that helps. (by the way, the new chain drive is quicker and quieter)

I have a sears 139.53647srt garage door opener. It is 16 years old. The nylon drive gear finally stripped. Is itt worth replacing the gear, or replace the whole unit. I am mechaically inclined, but can...


I think buy a new one in better choice. For its old equipment, maybe you'll hard to find compatible spare part anymore. But its your choice, if you love your door so much, and if you can find the spare part, just change the gear would be okay.

Hope this help.

I have a craftman garage door opener. I cannot close with remote. Please help me


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 nothing is blocking them. Each one has a small light that will be one when they are pointed correctly. If you can't get both lights to come on you need new sensors.

My Craftman Garage Door Opener is approx. 7 yrs old. Remotes work fine. Keypad acknowledges receiving code, but then will not open door. Installed new bsttery.


If your keypad is the same age as your door and worked before it has probably just quit. If it is new and you have programmed it and it still doesn't work it may be the wrong one for your model opener.

Craftman garage opener


The blinking LED is sending the code for "RPM sensor or motor overload. It isn't the motor or it wouldn't run at all. The RPM sensor is a small printed circuit board near the front of the motor. It will be available at Sears or any good door opener service company.

I CAN NOT PROGRAM MY BUILT IN CAR REMOTE ON MY NEW 139.53985DM


didnt try everything cause if you did, it would work! Get two people and garage door opener. One read manual from car under Garage door" or Homelink while other pushes button. When manual says if this did not work or if you have security plus or rolling code, continue with other instructions. You will need a working remote and will need to pushh learn button on motor logic board.
