Troubleshooting
The garage door doesn't operate from the MyQ
®
Home Control App or website.
•
When using Model 580LG Alternate Power Supply or when in Battery Backup mode, the Internet Gateway will not activate the garage
door through the MyQ
®
Home Control App. If you wish to use the Internet Gateway with your garage door opener, please contact
your local electrician to wire an outlet next to the garage door opener.
The garage door opener doesn't operate from either the Door Control or the remote control:
•
Does the garage door opener have electric power? Plug a lamp into the outlet. If it doesn't light, check the fuse box or the circuit
breaker. (Some outlets are controlled by a wall switch.)
•
Have you disabled all door locks? Review installation instruction warnings on page 7.
•
Is there a build-up of ice or snow under the door? The door may be frozen to the ground. Remove any restriction.
•
The garage door spring may be broken. Have it replaced (see page 3 for reference).
•
If the yellow command LED does not turn on, reverse the wires connected to the RED and WHT terminals of the control panel.
Replace wire if necessary.
The yellow and red LEDs on the Door Control are blinking quickly:
•
The control panel is charging, and may take up to 5 minutes to become operational.
My remote control will not activate the garage door:
•
Verify the lock feature is not activated on the door control.
•
Reprogram the remote control.
•
If the remote control will still not activate the door check the diagnostic codes to ensure the garage door opener is working properly.
The remote control has short range:
•
Change the location of the remote control in your car.
•
Check to be sure the antenna on the side or back panel of the garage door opener extends fully downward.
•
Some installations may have shorter range due to a metal door, foil backed insulation, or metal garage siding.
The door doesn't open completely:
•
Check power door lock.
•
Is something obstructing the door? Is it out of balance, or are the springs broken? Remove the obstruction or repair the door.
The door opens but won't close:
•
Check cable tension monitor (see Installation Step 4).
•
If the garage door opener lights blink, check the safety reversing sensor (see Installation Step 9).
•
If the garage door opener lights don’t blink and it is a new installation (see Adjustment Step 2). For an existing installation, see
below.
Repeat the safety reverse test after the adjustment is complete.
The door reverses for no apparent reason and garage door opener lights don’t blink:
•
Check cable tension monitor (see Installation Step 4).
•
Is something obstructing the door? Pull the emergency release handle. Operate the door manually. If it is unbalanced or binding, call
a trained door systems technician.
