1. Check to ensure there isn’t anything in front of the garage door opener’s eye.
2. Check for any debris/blockage in the garage overhead door’s rails.
3. Check if it closes fully using the Guardian app.
4. Power cycle the garage door motor by unplugging the power adapter. Wait 1 minute. Plug back into power.
If it still won’t close completely, please give us a call at 1.800.PROTECT (1.800.776.8328) to have your garage door opener serviced.
