If the LED light indicator is off and the door doesn't respond, it could be due to several reasons. First, ensure that the power switch is on. Check all cable connections to make sure they are securely connected. Inspect the cable for any damage and replace it if necessary. Verify that the power plug is properly inserted. If none of these steps resolve the issue, the door assistant may be defective and require replacement.
