These are additional troubleshooting issues that will not show up in the
diagnostic codes:

such as Timer-to-Close or garage door monitor.
My remote control will not activate the garage door:
• Verify the lock feature is not activated on the door control.
• Reprogram the remote control.
• If the remote control will still not activate the door check the
diagnostic codes to ensure the garage door opener is working
properly.
