Why isn't my Craftsman garage door opener learning?

Your Craftsman garage door opener may not be learning or programming remotes due to several reasons including wrong Learn button procedure, remote compatibility, range, or logic board failure, as Craftsman openers are made by Chamberlain Group and share similar programming. First, check if you are pressing Learn button correctly, Craftsman Learn button is on motor unit on ceiling, color varies purple, yellow, red, green, press and release Learn button, LED lights steady for 30 seconds, within 30 seconds press remote button until lights flash, if you hold Learn button too long you erase codes instead of entering learn mode. Second, check remote compatibility, Craftsman openers use Security+ rolling code, remote must match Learn button color frequency, for example yellow Learn button requires Security+ 2.0 remote, purple requires 315 MHz remote, check remote model compatible. Third, check remote battery, dead battery prevents learning, replace battery. Fourth, check if memory full, Craftsman openers can store limited number of remotes, if memory full new remote won't learn, erase all codes by holding Learn button for 6 seconds then reprogram. Fifth, check for interference from LED bulbs or nearby devices. Sixth, check if logic board failed due to power surge, if no remotes learn and wall button also not working despite power, board may need replacement. Follow manual for your Craftsman model number.
