Craftsman Garage Door Opener Troubleshooting Flashing Light 10 Times

When a Craftsman garage door opener's indicator light blinks 10 times, it typically indicates that there's a problem with the door's safety system. Here are a few steps to help troubleshoot this issue:

Check the safety sensors: The safety sensors are located on either side of the door frame, about 6 inches above the ground. Make sure that the sensors are aligned and not blocked by any objects. If the sensors are misaligned, adjust them so that they face each other directly.
Check the wiring: Inspect the wires that connect the safety sensors to the opener. Make sure that the wires are not damaged or loose. If any wires are damaged, replace them with new ones.
Check the logic board: The logic board is the main control unit for the garage door opener. If the logic board is damaged, it may cause the opener to malfunction. To check the logic board, remove the cover of the opener and inspect the board for any visible damage. If you see any burned or damaged components, replace the logic board.
Reset the opener: Sometimes, resetting the opener can resolve the issue. To reset the opener, disconnect it from power for 30 seconds and then reconnect it. Once the opener is reset, try operating the door again.

If you have tried all of the above troubleshooting steps and the issue persists, you may need to contact a qualified technician to repair the opener.
