Remotes won't work

I have a craftsman 1/2hp opener part #41a5021-2g 2002 model year. The remotes always worked until 2 days ago. They quit working for no apparent reason. I changed batteries but no luck. Any help would be appreciated

    Remote was working and then quit all of a sudden. I have replaced the batteries and it works if I am under the motor but does not work when I move more than 15 feet away it will not work.

Sounds like a frequency issue. A remote work like the radio in your where each station is on a different frequency. Some signal is interfering with you frequency (390Mhz) You could try another brand external receiver with new remotes or with that old of an operator you might just think about replacing the operator (don't go with "Wayne Dalton")

Sounds like your receiver has quit working. To program the remotes do this: Press and hold the button on the remote while you press and immediately release the smart/learn button. Do this for each remote. If this doesn't work your logic board is bad.

I suggest you look for a Chamberlain dealer in the yellow pages and explain what you have. You are looking for a 'universal receiver' that will work with what you have.

I would pull the logic board and check for loose or missing connections/traces on the printed circuit board. You can also foll the 110v line and make sure it has not worked loose.

Remotes quit working on Craftsman 53975 garage


It sounds like you have a logic board problem. If your remotes work at all it is not a programming problem. You could pull the logic board and check for loose connections especially around the small transformer. 18 years for an opener is very lucky. Their average life is about 1/2 that.

Only 1 remote will work at a time


One of your remotes has reverted to an earlier technology and they will no longer work with each other. You need to purchase a new remote making sure you get the same model number. Then you will find you can program 2 that will work with each other and 1 that will not. Remove the battery from the bad remote and toss it so that it doesn't cause problems down the road.

Only opens when remotes are close


The problem is in the receiver on the logic board. You will have to replace the logic board. You can get a replacement part at searspartsdirect.com. Thanks BB

Remote opener


Have you tried to re-learn the remote? The instructions should be inside the opener cover.
