Garage Door Safety SensorsPhiladelphia, PA - Safety sensors are extremely crucial and are now required for any garage door opener installation. Getting safety sensors can be thought of as the most sensible method. 


Your Guide To Garage Door Safety Sensors

Just like all other devices, garage door safety sensors malfunction if it is exposed to dirt and if it was not undergone maintenance. 



As an owner of the garage door safety sensors, it is your responsibility to know some information about it to avoid future incidents and troubleshoot future issues. 

How to test a garage door sensor?

Now that you understand how garage door sensors work, you can put them to the test. It's simple to figure out if your garage door sensor is broken. Once you've determined that the problem is with the sensors, the fix is usually simple enough for you to do yourself.



You'll need a common everyday object like a cardboard box to test your garage door sensor. Close the garage door by placing the box in the line of the sensors. Your door is working properly if it reverses after sensing an obstruction. 

If the box's door closes, you'll need to troubleshoot and check for symptoms that something is amiss with the sensors. Since it has the added security that sensors give, it's critical that you maintain your garage door and all of its components on a regular basis to verify that everything is in functioning order. If you see that you are requiring a garage door spring repair or roller replacement you should call a professional since they are parts held by a lot of tension. 



Signs to determine the underlying problems on your sensor

If your garage door sensors aren't working, you can troubleshoot to find the source of the problem. There are a few indicators that can assist you to figure out what's wrong with your garage door sensor. You can decide whether to fix the problem yourself or hire a professional after checking them.

Light indicators

Check if the exterior LED light blinks when you try to close the garage door to see if your garage door sensors are out of line. The sensors are operating if the lights are green, however, they have not aligned if the lights are red.

Inspect the bracket or tighten a screw on the blinking sensor if you observe red lights. If the light stops flashing and your garage door closes properly again, you've corrected the sensor.

Filthy lenses

Sometimes all you need is a clean cloth to fix your garage door sensors. When dirt or spider webs obscure the sensor lenses' view of the garage door opening, they may fail to function. 

Cleaning the lenses will allow your door to function normally. If your garage is particularly filthy or your neighborhood is notorious for dust, you should clean your sensors on a regular basis

Damaged wires

The wires that connect the garage door sensor system might deteriorate over time due to constant use, weather, and even pests. The wires can be harmed by rain and wind, pest infestations, and the use of equipment. 

Examine the wires for signs of tampering, such as water damage, gnaw marks or other signs of tampering. 

Reasons why garage door sensors stopped working

  • Object blocks the lenses path
  • There is a problem with the sensor’s power supply
  • On both or one sensor, LED lights are not glowing
  • The lenses of the sensors need to be cleaned because of the dirt and spider webs
  • The sensors were being exposed to too much moisture
  • Sensors are not aligned properly. If the sensors are properly aligned, their LED lights should be lighted.
  • Your sensors were subjected to typical wear and tear, particularly if they were placed many years ago.

Another technique to verify that your sensors work properly is to check that they are properly aligned. If they're out of position, the beam may mistake it for an obstruction, preventing your garage door from closing. 

To fix this, look for any loose screws in the brackets that hold your sensors in place and tighten them. Bend the bracket till the sensors are in line with one another if it has to be modified.

Turn to a professional for extensive repairs or if you notice that your sensors are often malfunctioning. It helps you save money and avoid some major problems in the future.
