Troubleshooting
Additional Troubleshooting
My garage door opener stops, reverses, beeps and flashes its lights:
l Garage door opener has  been activated through  a device or feature such as Timer-to-Close or garage 
door monitor.
My remote control will not activate the garage door:
l Verify the lock feature is not activated on the door control.
l Reprogram the remote control.
l If the remote control will still not activate the door check the diagnostic codes to ensure the garage
door opener is working properly.
My door will not close:
The safety reversing sensor must be connected and aligned correctly before the garage door opener will 
move in the down  direction.
l Check for binding or obstructions anywhere along the track to garage floor.
l The safety reversing sensor must be connected and aligned correctly before the garage door opener
will move in the down direction.
o
Verify the safety reversing sensors are properly installed, aligned and free of any obstructions.
o
If the receiving sensor (green LED) faces direct sunlight, switch the receiving sensor with the
sending sensor so the receiving sensor is not in direct sunlight.
Wi-Fi® troubleshooting
The garage door opener will NOT enter Wi-Fi® learn mode:
l After the initial installation of the garage door opener, the garage door opener must complete a full
cycle (open and closed) before the Wi-Fi
®
learn mode can be activated.
l If there has been a recent power outage, the garage door opener must complete a full cycle before the
Wi-Fi
®
learn mode can be activated.

find  out if a Bridge is needed.
My neighbor’s remote control opens my garage door:
Erase the memory from your garage door opener and reprogram the remote control(s).
Safety sensor LED lights  are not lit:
