The garage door opener can beep for several reasons:
Operating on battery power or the 12 Vdc battery needs to be replaced, see page 31.
l
Garage door opener has been activated through a device or feature such as Timer-to-Close or garage door
l
monitor, see page 36.
My remote control will not activate the garage door:
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
l
is working properly.
My door will not close and the lights blink on my motor unit:
The safety reversing sensor must be connected and aligned correctly before the garage door opener will move in the
down direction.
Verify the safety reversing sensors are properly installed, aligned and free of any obstructions.
l
My garage door opener light(s) will not turn off when the door is open:
The garage door opener is equipped with a feature that turns the light on when the safety reversing sensors have been
obstructed or when the motion sensor on the door control detects movement in the garage. These features can be
disabled using the door control, see page 35.
Wi-Fi troubleshooting
The garage door opener will NOT enter Wi-Fi LEARN mode:
After the initial installation of the garage door opener, the garage door opener must complete a full cycle (open
l
and closed) before the Wi-Fi LEARN mode can be activated.
If there has been a recent power outage, the garage door opener must complete a full cycle before the Wi-Fi
l
LEARN mode can be activated.
See page 32 to activate Wi-Fi LEARN mode.
If your black adjustment button is not solid green go to support.chamberlaingroup.com.
SYMPTOM
The garage door opener will not close and the lights flash.
SOLUTION
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.
My vehicle's Homelink is not programming to my garage door opener:
Compatibility Bridge (not included) may be necessary for certain vehicles. Visit bridge.chamberlain.com to 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).
