SYMPTOM
Door is moving, stops or reverses. Opener beeps and lights flash.
Opener runs approximately 6-8" (15-20 cm), stops and reverses.
The garage door opener will not close and the lights flash.
SOLUTION
Manually open and close the door. Check for binding or obstructions, such as a broken spring or door lock,
correct as needed. If the door is binding or sticking, contact a trained door systems technician. If door is not
binding or sticking attempt to reprogram travel (refer to 1).
Communication error to travel module. Check travel module connections, replace travel module if necessary.
Safety reversing sensors are misaligned or were momentarily obstructed. Realign both sensors to ensure both
LEDs are steady and not flickering. Make sure nothing is hanging or mounted on the door that would interrupt
the sensor's path while closing.
LEDs are not working:
Check wiring on both Integrated LED Light Modules to connector. If loose, then reconnect. If the lights do not
turn on, a new Integrated LED Light Module may be needed. Connect customer service or certified door
professional to determine if a new Integrated LED Light Module 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).

My camera won't connect to the router:
•
Move your router closer to the garage door opener to minimize interference from walls and other objects.
•
Buy a Wi-Fi® range extender.

®
