Yellow Light On Garage Door Sensor

When the yellow light on your garage door sensor is on, it usually means that the sensor is not aligned properly. This can happen if the sensor has been bumped or moved, or if the door has been misaligned. When the sensor is not aligned properly, it will not be able to detect when the door is closed, and the door will not open or close properly.

To fix this problem, you will need to adjust the sensor. First, check to make sure that the sensor is securely mounted in place. If it is loose, tighten the screws that hold it in place. Next, check to make sure that the sensor is aligned with the door. The sensor should be positioned so that it is directly in line with the edge of the door, and the light should be shining directly onto the reflector on the other side of the door.

If the sensor is still not aligned properly after you have adjusted it, you may need to replace it. Sensors can fail over time, and if the sensor is damaged, it will not be able to function properly. To replace the sensor, simply unscrew the old sensor and screw in the new sensor. Make sure that the new sensor is aligned properly before you tighten the screws.

Once you have replaced the sensor, test the door to make sure that it is working properly. The door should open and close smoothly, and the yellow light should turn off when the door is closed.

Other Causes of a Yellow Light on a Garage Door Sensor

In some cases, a yellow light on a garage door sensor can be caused by other factors, such as:

A power outage: If the power goes out, the sensor will not be able to function properly, and the yellow light will turn on. Once the power is restored, the sensor should reset itself and the yellow light should turn off.
A loose wire: If a wire in the sensor is loose, it can cause the sensor to malfunction and the yellow light to turn on. To fix this problem, simply tighten the loose wire.
A faulty circuit board: If the circuit board in the sensor is faulty, it can cause the sensor to malfunction and the yellow light to turn on. To fix this problem, you will need to replace the circuit board.
