Sensor issues with garage door.

A common cause of a malfunctioning garage door sensor is lack of power supply. Look for small led lights on the sensors. The while idea behind garage door sensors is to be able to block the garage door. If they re turned on in both the sensors then there is no issue with the power supply.

Another very common issue is that your garage door sensors may be blocked by something in the garage itself. If you do not see a solid illumination or your garage door is not working the problem is most likely due to the sensors being out of line. Many people use their garage to store things whether it s the lawnmower or boxes of items you re keeping for sentimental reasons. This is something that can also come handy when your car is in the driveway.

The first is an obstruction in the path of the door and therefore in the path of the sensor. Remove any debris dust or cobwebs from the electric eye lenses on each sensor with a clean rag. If you find the lights turned off in one or both the sensors it indicates that there is a problem in power supply. Two types of accidental obstructions can cause the safety sensor to prevent a garage door from closing.
