If you see the up arrow blink only once and the down arrow blink twice, it means that your garage door opener would not close.

This means that the safety sensors or what is called the photocells are not correctly installed or not properly connected.

Following the instructions looking at the blinking arrows as mentioned above, if you’ve noticed that both the up and down arrows blinked only once, it means that the problem is that the garage door opener is not able to close itself.
