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

1 Answer

Antenna/distance I can usually open the door from the street. This afternoon I could not even open the door from the driveway. I reset the codes to the hand held remotes and the keyless entry, no matter. When I was in the garage the remotes work and the keyless would work with the door open, it would close but would not open with the keyless (the signal would not go through the door. I pushed the wire antenna back in to the main body, which changed the make up. This gained me some more distanced and now the keyless will open and close the door. I have an antenna problem that at this point I do not know how to fix at this point?

Sliding gate wont always open


Since there are few details on the circumstances of when it won't open provided I will try to guess what is happening.

Usually this is related to the strength of the transmitter (clicker or remote) signal. If you have radio interference from ham radios, air fields or other government agency, it will affect the reception or your gate receiver. Other common issues include the distance from the operator, how long you hold down the button, and the age of the battery in the transmitter.

You might try extending the receiver antenna up higher. If this makes it worse, you may need a directional antenna like the Linear EXA 2000.

We have also found the Linear SMDRG narrow band receiver to work well when we have interference issues.

My liftmaster 1265 won't open with the remote, unless I am standing under motor assy. I just purchased a new remote model 375LM. I don't know what I need to check or do to increase the distance I can be...


No range on your remotes or loss of code all together is a receiver problem not a remote problem, You probably did not need a new remote.
You can try to extend the antenna ( wire hanging from the motor) for more range
Or Unplug the motor from the outlet wait 30 seconds and plug back in ( trying to reset the circut board). Also If you are useing florecent bulbs in the garage ( the little twisted ones) these can affect the range on the remote.

CHAMBERLAIN WILL NOT RESPOND TO REMOTES FROM STREET.


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.
