I have a Liftmaster and the Xfire Homelink works my garage door just fine.

I just followed the instructions in the Manual carefully, and it worked the first time.

I believe that Liftmaster is the OEM Manufacturer for the Craftsman (sold by Sears), but I may be wrong.

Might not be a bad idea to use this thread to list the various openers that have been successful with Homelink...!!!
