Few things are more frustrating than a garage door that won’t close because of a faulty sensor. If your garage door sensors aren’t working, you could be dealing with dirty lenses, wiring issues, or more.
Knowing the common causes of malfunctioning garage door sensors and how to fix them can save you time and frustration.
Six Common Reasons Your Garage Door Sensors Aren’t Working
Why do sensors fail? Any of the following issues may be to blame.
1. Equipment Misalignment
Garage door sensors must be perfectly aligned to work properly. If they fall out of place, the infrared beam won’t connect.
To fix this, check both sensors and ensure they face each other. Most sensors have indicator lights that signal alignment. If the lights are off or blinking, adjust the sensors until they stay there.
2. Dirty Lenses Block Beams
Dirt and grime can block the sensor lenses, making it impossible for them to detect the infrared beam. Gently wipe each lens with a microfiber cloth to remove buildup.
Avoid using harsh chemicals, as they can damage the sensors. Regular cleaning helps prevent future problems.
3. Wiring Issues Prevent Garage Door Operation
Loose or damaged wiring is one of the biggest reasons why your garage door sensors aren’t working. Over time, wires deteriorate due to wear and tear, moisture, or even pests.
Inspect the wires for damage or loose connections. If you find frayed or disconnected wires, turn off the power before reconnecting or replacing them. If the wiring looks intact but the sensors still don’t work, consult a professional.
4. Sunlight Interference Impacts Sensor Performance
Bright sunlight affects infrared sensors, making it difficult for them to function properly. This problem is especially common in garages that receive a lot of direct sunlight.
If sunlight hinders your sensors, try shading them with small pieces of cardboard or adjusting their position slightly. You can also install sun shields designed specifically for garage door sensors.
5. Power Failure Shuts Down Sensors
If your garage door opener has no power, the sensors won’t work. A tripped circuit breaker, unplugged opener, or drained backup battery could be the culprit.
Keep the opener plugged in and restore power to a tripped circuit breaker. If your system has a backup battery, ensure it’s charged and working properly.
6. Obstructed Beams Cause Sensor Malfunctions
A tiny object blocking the sensor beam can stop your garage door from closing. This could be anything from a piece of debris to a misplaced tool.
Inspect the area around the sensors and remove any objects in the way. Even cobwebs or leaves can block the beam, so keep the area clear.
