home and garden smart homeWhy does my Craftsman garage door opener blink?
The blinking opener lights indicate that the safety sensors are likely blocked or out of alignment. Defective safety sensors or faulty sensor wiring also cause the opener lights to blink 10 times. The safety sensors use an invisible beam of infrared light to detect obstructions in the garage door's path.
Similarly, it is asked, what does it mean when the garage door opener is blinking?
The most common reason for the lights to flash on the garage door opener and the door not closing is that the safety reversing sensors are misaligned or obstructed; this is a safety feature of the garage door opener. Four (4) flashes indicate the sensors are slightly misaligned.
Moreover, how do you align sensors on a garage door opener?
How to Align Safety Sensors On Your Garage Door
- Remove the receiving sensor (green light) from bracket. You can do so by taking off the wing nut.
- Point the sensor away from the sending sensor, so that the light is completely off.
- Once the light is off, wait 10 seconds.
- Slowly rotate sensor back, aligning sensor with sending sensor, until it lights up green again.
If the door goes up but goes down only when you hold down the wall switch, check to see that the safety sensors are in alignment. The small light on each sensor should be lit up when nothing is between them. Door sensors do go bad, so if no light is showing at all, you may need to replace them.
