Are you having trouble with your garage doors not closing correctly?
When your garage doors aren’t closing all the way, faulty sensors are one of the most common culprits. And fortunately, sensors are easy enough to check out on your own. That’s why it’s a smart move to troubleshoot your sensors yourself before calling a professional. The fix might be as simple as cleaning the lenses or tightening a screw.
So, without further ado, let’s take a look at how to troubleshoot your garage door sensors.
Simple Sensor Test
First, you need to confirm that your sensors are the actual problem. Thankfully, the test is simple. Here’s what you do:
- Take a random, disposable object, like a cardboard box.
- Find where the sensors are located and place the object in line with them.
- Try closing the garage door. Working sensors will stop the door from closing onto the object.
- If the door closes onto the object, then you know the sensors are not working correctly.
Check the Light Indicators
When you try to close the doors, watch the sensor lights. Are they blinking red or green? Green means the sensors are aligned correctly, but red means they’re out of alignment.
If the lights are red, the sensor might just need to be tightened. Try adjusting the bracket or screw, then repeat the sensor test to verify that it’s fixed.
Clean the Sensor Lenses
Take a look at the sensor lenses. Are they dirty or covered in cobwebs? If they’re not clean, they may send a false signal, which prevents the door from closing even when nothing is in the way.
Wipe them clean with a soft cloth, then repeat the sensor test. Hopefully, this does the trick.
Inspect the Wiring
Check your system’s connective wires. If there are signs of water damage, chew marks, corrosion, or any other deterioration, then you’re looking at an electrical problem. Unfortunately, this is the one fix you should not attempt yourself. Instead, you’ll need the help of a professional garage door company like Easy Open Garage Doors.
