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

1 Answer

My remote intermittenly opens/closes the garage door

I have a sears 76LE garage door opener. we bought the house used and don't know how old the opener and remote are. I changed the battery in the remote and the problem still exists. when i leave in the morning, sometimes the remote will close the door and sometimes it won't. the wall unit always opens/closes the door. when I return 9/10 times the remote will open the door. I'm hoping it's as easy as finding a universal remote and reprogramming it. but, which make/model?

You can find a free manual for your door opener at manualsonline .com You might want to look at how to program it and change the unit to a different frequency. You can sometimes get better response and eliminate interference. Also make sure your battery contacts in the remote are clean.

The garage door remotes and keypad works only when i,m very close to opener, will not work at more then 6 ft away from opener. sears hbw0777


How old are the batteries in the remotes and keypad? Replace the batteries. If that helps, then you have solved the problem.

If it doesn't help, then check the antenna wire of the opener. (Make sure it is extended down from the unit.) Note this doesn't apply to all garage door openers. (We have several models - some with the external antenna and some without.)

Does your garage have metal walls and metal doors? This can shorten the range between the receiver and the remotes or keypad. An antenna extension may be available.

I don't see the HBW077 as a model number at Sears Parts Direct or Manage My Life. Please check the model and let me know if I can provide any additional assistance. (Sears Parts Direct has parts for my garage door openers. Manage My Life has manuals for Craftsman and Sears appliances.)

I hope this helps.

If you didn't, try programming the remote this way.

Press and hold the button on the remote and then press and immediately release the smart/learn button on the motor unit. If this doesn't work you need to make sure you have the correct remote for the model opener you have. Your model number doesn't bring any results from Sears Parts.com.

Post the model number of the opener and the model numbers of the remotes. The opener model number is found on the end closest to the door and starts with 139.

Try 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.

After programming the keypad see if either remote will work with it. Post this information also.

On the remotes put switch #1 in either position and match up switches 2 through 10 to the dipswitches on the motor unit. There is a good possibility your receiver has quit working.

If your opener is truly 25 years old there are not going to be any parts available. The model number you give is not the model number. It starts with 139. and probably has 6 numbers after the period or dash. Once you have it you can go to Sears parts and see if there are parts available.

I would remove the cover and take a good look at the limit switch assembly. If you watch it you will understand how it is supposed to work. There could be a bad connection on the logic board. You can remove it and check it over.

Remote to garage door opener wont work no solution on fixya


The Clicker is a hard one to program. You might try it a couple more times to be sure it won't work.
The 61LM is the Liftmaster remote that goes with that unit. There is a possiblity that the reciever on the board is bad. That board is no longer available but you can get a 635LM external reciever that is backward compatable with the 61LM remote.
