When you see you garage door opener lights flashing and the garage door will not close, it could be the LOCK button or the safety reversing sensors.
NOTE: If necessary, you can close the garage door by pressing and holding the door control push bar until down travel is completed.
Start by checking if:
- The LOCK button on the door control in ON.
- Check if the safety reversing sensors are aligned.
Unlock the LOCK Button
If your door control has a LOCK button, it may have been turned on. When the LOCK button is ON, the garage door opener will work from the door control but the remote controls are locked out.
- Press the LOCK button to turn this feature off. The light will flash two times.
- Press the remote control. If the door closes, your issue is solved.
Align the Safety Reversing Sensors
The safety reversing sensors may have become misaligned or obstructed. Possibly, there is a problem with the sensor or wiring. See How to align safety reversing sensors.
