Garage Door Opener question

I have a Craftsman garage door opener and have a remote that quit working. Yes, the batteries are good, per battery tester and swapping batteries with the other remote. It has the roving codes and has the 3 button remote with the beige buttons. A new remote is $40. It seems to be the same opener that Chamberlain makes. Does anybody know if the 850CD or 750CB Chamberlain remotes would work with this opener? They are only about $17 on sale now locally. Thanks.

One remote works, the other doesn't. That does not affect opening. That also does not affect resetting the transmitter to work with the receiver. It does not produce the blinking green light on the receiver.

Check ebay and find an exact model. There are three basic models and you have to know which one you have. Some have dip switch settings (these were made until about 1993), another model is programmed automatically by your operner, and I believe that latest model has a new kind of security.

Yes the remotes are made by the same company. Not sure on the model numbers but as long as they are Security+ (rolling code) they will work. So will the Liftmaster 973LM. However, if your transmitter has the small 12V battery, before you buy a new transmitter you may want to open the transmitter & clean the battery contact post w/ sandpaper or emery cloth. They have a tendency to oxidize or corrode. After cleaning them squeeze them in toward each other before putting the battery back in place to assure solid battery contact
