Garage Door Opener Is Blinking
If your garage door opener is blinking, it could be a sign of a problem. The most common cause of a blinking garage door opener is a problem with the sensors. The sensors are located on either side of the garage door and they work together to create a beam of light. When the door is closed, the beam of light is unbroken. When the door is opened, the beam of light is broken and the garage door opener stops the door from opening.
If the sensors are misaligned, the beam of light will be broken and the garage door opener will think that the door is open. This will cause the garage door opener to blink. To fix this problem, you can try to realign the sensors. The sensors should be facing each other and they should be about 6 inches apart.
If the sensors are not misaligned, the problem could be with the wiring. The wires that connect the sensors to the garage door opener can become loose or damaged. This can cause the garage door opener to blink. To fix this problem, you can try to tighten the wires or replace them if they are damaged.
If the wiring is not the problem, the problem could be with the garage door opener itself. The garage door opener could be malfunctioning or it could be damaged. To fix this problem, you can try to reset the garage door opener or you can replace it if it is damaged.
