However, when these sensors stop working correctly, it can cause frustration and potentially make your garage door unsafe. At The Up & Up Garage Doors in Austin, TX, we’ve helped countless homeowners with garage door sensor repairs. In this blog, we’ll explain how sensors work, common sensor problems, and how they can be fixed.
How Do Garage Door Sensors Work?
Garage door sensors are a key safety feature that uses infrared technology to detect objects in the path of the door. These sensors are located near the bottom of your garage door tracks on both sides. Understanding Garage Door Sensor They communicate with each other by sending a beam of light across the garage opening. If something (like a toy, pet, or even your foot) crosses this beam while the door is closing, the door will stop and reverse to prevent an accident.
Common Garage Door Sensor Problems
Over time, garage door sensors can encounter issues that prevent them from functioning correctly. Here are some of the most common problems we’ve seen at The Up & Up Garage Doors:
Misaligned Sensors
If the sensors become misaligned, Understanding Garage Door Sensor they won’t be able to communicate properly, which may cause your door to stop working altogether.
- Signs of Misalignment:
- The garage door stops and reverses when you try to close it.
- The sensor lights are blinking or off completely.
- The door closes unevenly.
Dirty Sensor Lenses
The lenses on garage door sensors are sensitive and can become dirty over time. Dirt, dust, or debris can block the infrared beam, causing the sensors to think there is something in the way.
- Signs of Dirty Lenses:
- The door starts to close but reverses.
- The sensor lights are on, but the door won’t close properly.
Damaged Wiring
The wiring that connects your garage door sensors to the door opener can become damaged due to wear and tear or even pests. Damaged wires can disrupt the signal between the sensors and the opener.
- Signs of Damaged Wiring:
- No lights are visible on the sensors.
- The door doesn’t respond at all when you try to close it.
Obstructions Blocking the Sensors
Sometimes, the problem can be as simple as an object blocking one of the sensors. This could be something as small as a leaf or even a piece of trash in the sensor’s path.
- Signs of an Obstruction:
- The door starts to close, then immediately reverses.
- The sensor light flashes, indicating something is in the way.
How to Fix Garage Door Sensor Problems
While some garage door sensor problems can be fixed quickly, others may require professional help. Let’s take a look at the steps you can take to troubleshoot common sensor issues.
Check for Obstructions
Start by making sure that nothing is blocking the sensor beam. Clear any debris, leaves, or objects from around the sensors to ensure they have a clear line of sight.
Clean the Sensor Lenses
If the lenses on your sensors are dirty, use a soft cloth to gently clean them. Avoid using harsh cleaners that might damage the lenses. A simple wipe-down can often fix minor sensor issues caused by dirt and grime.
Align the Sensors
If your sensors are misaligned, you can try to realign them yourself. The sensors should face each other directly, and the indicator lights on both sensors should be solid, not blinking. Here’s how to adjust the sensors:
- Step 1: Loosen the screws holding the sensors in place.
- Step 2: Gently move the sensors until they are directly facing each other.
- Step 3: Tighten the screws to hold the sensors in place.
Check the sensor lights. If they stop blinking and are now steady, you’ve likely fixed the problem!
Check the Sensor Wiring
If you notice that your sensors aren’t lighting up at all, it could be due to damaged wiring. Inspect the wires for any visible damage like cuts, fraying, or signs of wear.
