Is your garage door sensor not working? A malfunctioning sensor can result from a number of factors. But, no matter the cause, the results remain the same: inconvenience.

This is why it is important to be familiar with the causes of your garage door sensor not working. Carry on reading this blog to find out!

Reasons Your Garage Door Sensor is Not Working

Here are some reasons why your garage door sensor might not be working:

1. Signal Transmission is Blocked

A few centimeters off the ground, you will find the two photo eyes of the garage door. These photo eyes communicate by sending a transmission. Hence, when something interrupts the signal transmission, your garage door will stop working. Therefore, make sure to check nothing is blocking the area.

2. The Sensor is Dirty

Sometimes, the problem is much simpler than it seems. It’s possible that your sensors have collected dirt, which stops them from functioning properly. Coupled with your car exhaust, the debris can accumulate on the sensor and interfere with the sensor’s performance. Moreover, spiderwebs might also gather up on the sensor. The solution is to give your garage door and the sensors a thorough cleaning.

3. Sunlight Affecting Signal Transmission

When sun rays enter your garage, they can also affect signal transmission. This is because the sunlight might send the wrong signal that an object is blocking the path. Experts suggest switching the sides of sensors if this is the case. However, you can contact a professional garage door service for the best solution.

4. Misalignment in Sensors

Sometimes, the sensors are misaligned and leading to issues with the garage door operation. For this, you will need to check the placement of both garage door sensors. Flickering lights are another indication of sensors being moved from their proper position. You can ask a professional to align your garage door sensor for proper function.

5. Problems With Photo Eye

A bad or busted photo eye will prevent the sensor from working. Therefore, flickering light or other issues could suggest that there is a problem with the photo eye. Other than this, damaged wiring of the photo eye will compromise the operation of sensors. Call a professional for garage door repair if you notice this issue.

6. The Outlet is Not Supplying Power

Another reason why your garage door sensor is not working could be that the machine is not receiving any power. If the electrical outlet stops supplying power, it could also cause issues with the sensor. Consult a professional on how to fix this problem. They might tell you to plug in any appliance in the outlet to see if they work. If yes, then the system’s wiring or plug may have an issue. Otherwise, you will need to inspect the power source. Chances are, the circuit tripped. However, it’s best to let an experienced person handle it.

7. Issues With the Remote Control

Sometimes, the remote control is to be blamed for the malfunctioning sensor. Suppose your garage door is operating well by the wall switch. In that case, you will need to replace the batteries of your remote control. But, sometimes, the remote control might start acting up even with new batteries. If so, just check the operating instructions or contact the manufacturer.
