If you ever see the "Front Cover Missing" error message, you will need to check that the front panel is securely connected to the base of the unit. You cannot complete a calibration if the front panel is not screwed in place.
If the front panel is attached, please follow the below instructions:
Press the menu button to wake the screen
Press and hold the menu button until the message "Continue?" appears
Select "YES" using the up button
Using the up button, navigate to "Cover Sensing", using the menu button to select this option
Select "NO" using the down button
Press the up button to get to "Exit", using the menu button to select this option
You will then need to recalibrate the door.
What if the motor still does not respond?
