Troubleshooting
Troubleshooting (Continued)
The garage door opener strains to operate door:
• The door may be out of balance or the springs may be broken. Close the door and use the emergency release handle
to disconnect the door. Open and close the door manually. A properly balanced door will stay in any point of travel
while being supported entirely by its springs. If it does not, disconnect the garage door opener and call a trained
door systems technician.
The garage door opener motor hums briefly, then won't work:
• The garage door springs may be broken. See above.
• If the problem occurs on the first operation of the garage door opener, door may be locked. Disable the power
door lock.
The garage door opener won't operate due to power failure:
• Manually open the power door lock.
• Use the emergency release handle to disconnect the door. The door can be opened and closed manually. When
power is restored, pull manual release a second time.
• When in Battery Backup mode, the opener should be able to operate up to 20 times.
• Disable any door locks. Use the emergency release handle to disconnect the door. The door can be opened and
closed manually. When power is restored, pull manual release a second time.
• When in battery backup mode, battery power will last for 30 hours or up to 20 cycles over a 24 hour period.
Door loses limits:
• Collar not tightened securely. Tighten collar and reprogram limits (see Adjustment Step 1).
The garage door opener moves when the door is in operation:
• Some minor movement is normal for this product. If it is excessive the collar will wear prematurely.
• Check to make sure the torsion bar is not moving left/right excessively.
• Check to make sure the torsion bar is not visibly moving up and down as it rotates.
• Check that the opener is mounted at a right angle to the jackshaft. If not, move the position of the mounting bracket.
Automatic door lock connector will not fit the door opener plug:
Older model 24V door locks are incompatible. Use automatic door lock model 841LM, see Accessories page
Automatic garage door lock does not activate when garage door opens or closes:
In battery backup mode, the automatic garage door lock will unlock when the garage door is opened, and will remain
disabled until power is restored.
The door opener is beeping:
• Indicates unattended closure. The opener has been activated by the myQ App or the Garage and Gate Monitor.
• A solid orange LED with beep, sounding approximately every 2 seconds, indicates the door opener is operating on
battery power.
• A flashing orange LED with beep, sounding every 30 seconds, indicates the battery is low.
• A solid red LED with beep, sounding every 30 seconds, indicates the 12V battery will no longer hold a charge and
needs to be replaced.
The garage door is beeping and the red LED is flashing:
The battery charge is low or the battery is dead.
• Replace the battery.
