Common Reasons a Garage Door Sensor Stops Working
(& How to Fix It)

Garage Door Sensor Replacement

As such, it’s best for you to learn how to adjust garage door sensors or decide when to replace these devices. 

Many businesses can help you with choosing a new sensor model. There are also tons of options in the market, so you can match and purchase sensors that suit your needs.

signs for necessary sensor replacement

The first question you can ask is, “when should I replace the sensors?” There are some strong signs that you should replace the sensors instead of booking a repair. Newer sensor devices can be more reliable than old ones with inefficient functions and power consumption.

sensors are old

Sensors are mandatory items inside any garage. According to US laws and regulations, since 1993, all garages should be equipped with working sensors. Many brands and models of sensor devices are durable enough to last decades. As such, garage owners from that time may still have the same sensors inside the tracks from the 1990s. If the sensors are too old, it has undergone a lot of weather damage and exposure. It’s best to know how to replace garage door sensors or book for garage door sensor replacement. Keeping all garages safe is a top-notch priority for every property owner. This can only happen with pristine tools in mind, so scout for newer models and brands that suit your garage. 

severe sensor dAMAGE

The main reason you need to know the installation process or book for replacement service is damage. The door sensors are some of the most exposed items inside the garage. Imagine the daily weather conditions bringing a lot of factors that can cause the sensor material to deteriorate. The unsolicited impact from moving vehicles or obstruction can also contribute to the damage of the sensor.

 

The photo-eye lens may be too dirty or under too much damage from the sun. Rainwater may be causing moisture leaks inside the photo-eye build of the sensors. Calamities may end up destroying the brackets or loosening the holding hardware in the tracks. Moreover, severe force and impact can cause the sensor to break eventually and not function.

AUTO REVERSAL METHOD DOESN'T WORK

The primary function of the garage door sensor is to prevent the traversing of door panels when there is an obstruction. Anything blocking the light beams SHOULD signal the door opener to stop the door panels from descending. The auto reversal mechanism should work as soon as the light beam or the LED light indicator turns red.

 

A dysfunctional sensor can cause a lot of potential accidents inside the garage. Imagine if you have pets, children, or bigger items standing in the path of the traversing door. If the sensors don’t signal the obstruction, people get hurt, and things get broken. It’s better to replace the sensors if you notice that the auto reversal isn’t as effective and efficient as before.

CONSTANT FALSE SIGNALS

The photo-eye of each sensor is responsible for detecting the obstruction. It’s also the source of the light beam of the sending sensor, which is beside the LED light indicator. Sometimes, the photo eyes send the wrong signal to the garage door opener. You will have a hard time closing the garage, even if nothing is blocking the pathway.

If there are too many false signals from the sensor, then the damage may be severe. The sensor circuit may be corroded, or there is damage to the sensor’s circuit board. Consider finding a replacement sensor to ensure that there will be no false signals causing the garage to stay open.

obvious signs of wear and tear

 

Since the sensors are exposed all the time, wear and tear will appear. Check for scratch marks and signs of damage around the build of the sensor. If there are dents and wedges in the bracket, the bracket may lose hold of the sensor. Find new brackets, or replace the sensor set, which includes the mounting bracket of the device.

 

Check for any scratches in the glass of the photo eyes. Scratches can lead to water build-up and moisture inside the sensor’s lens. The water build-up can end up corroding and causing damage to the sensor. Replace the sensors with newer units.
