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

2 Answers

No response to remote on Liftmaster 1/3 HP model # 1245R

When i use the switch on the wall the garage opens and close just fine. But when i try to use my remote, nothing happens. The little light at the back of the unit just blinks and nothing else happens. Just for information the sensors seem to work fine so i am pretty sure that is not the problem. Any help please?

It has probablly lost sync.

Follow the procedure to reload the codes. One usually has to hit a reset button on the head and then follow a sequence to sync your remote to the head.

We have the same model and similar difficulties. We were told it's a bad antena. Not sure if there is anything we can do about this. Sometimes it works with the remotes, sometimes not. Always works with the wall switch, because that's wired.

If your keypad doesn't have the enter button it is an earlier model and will not work with what you have now. You will need to call your Liftmaster dealer to get the latest model.

If the main light flashes 10 times when you try to close the door it is a sensor problem. Make sure they are not flickering ever so slightly and that they are not loose on their brackets. Tweak them a little bit.

No reponse when using the remote, the wall control works fine.


The remotes use a receiver to actuate the door and the wall control does not. It sounds like your logic board is bad. Maybe a lightning storm recently? Try removing the board and look for burnt or missing traces on the printed circuit.

I have no idea what a 132C2105-3B is but try this. Hold the button down on the remote and then press and immediately release the smart/learn button. If the remote is the correct one for your opener it should work.

Garage door opened, won't close


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.
