Craftsman opener learn LED blinks rapidly and will not accept new remote programming.

Safety first: Keep remotes out of reach of children while programming to avoid unintended operation.

• Clear all remote codes: Press and hold the LEARN button on the opener until the LED turns off (about 6–10 seconds). This erases all remotes and keypads.
• Exit learn mode: Wait 30 seconds for the LED to stop blinking. Do not press any remote buttons during this time.
• Re-enter learn mode: Press and release the LEARN button once. The LED should glow steadily, indicating it is ready to learn a new device.
• Program remotes: Within 30 seconds, press the button on the Craftsman remote you wish to program. The opener light should blink to confirm.
• Check button: If the LED continues rapid blinking without input, the learn button may be stuck or the board memory corrupted, requiring logic board replacement.
