  • Look for a button or option labeled “Reset” or “Clear Error Code.”
  • Press the “Reset” or “Clear Error Code” button and hold it down for a few seconds until you see the amber and green lights on the opener flash simultaneously.
• Operate the Opener:
  • With the error code cleared, try opening and closing your garage door using your remote or wall-mounted control.
