Two types of accidental obstructions can cause the safety sensor to prevent a garage door from closing.
Garage door eye sensors problems.
This can happen from old age your basic wear and tear or even constant exposure to the sunlight.
Sensor power reconnect the sensor to its power supply a common cause of a malfunctioning garage door sensor is.
If the wiring is fine and your garage door opener is still not working then the problem may be that one of the sensors has simply failed.
Either the beam is broken by the problem and the garage door won t close at all or the beam isn t properly detecting obstructions and it will close on anything unlucky enough to be in the door s way.
The sun also carries infrared light which is more powerful than the light of the sensors.
The first is an obstruction in the path of the door and therefore in the path of the sensor.
Automated garage door systems explains why this happens.
Remove any debris dust or cobwebs from the electric eye lenses on each sensor with a clean rag.
Sensor path make sure nothing is obstructing the sensor beam in general garage door sensors block the door from.
Cycle the garage door through the opening and closing actions using the control on the garage wall.
This indicates that the sensor is.
Garage door sensors use infrared light.
Check for obstructions when photo eyes are working as they should you ll find that any obstruction in the door will.
Sensor path make sure nothing is obstructing the sensor beam 1.
Replacing the safety sensors is not a complicated job and is somewhat easy.
When the lumens of light from the sun surpass that of the infrared sensor light the sensors are not able to signal one another.
