Common Sensor Issues

Garage door sensors use infrared beams to ensure safe operation. Positioned on either side of the door, one sensor sends an invisible beam while the other receives it. If something obstructs this beam, the sensors detect the interruption and prevent the door from closing. This is when fixing garage door sensors might become unavoidable. Let’s discover the main issues so you can troubleshoot and fix them easier.
Misalignment: If garage door sensors are not lighting up, then the problem might lie in misalignment. Garage door sensors are usually placed near the floor on either side of the door. If they’re not positioned correctly, they won’t communicate with each other, and the door will fail. Impacts, vibrations, or even small movements in the mounting brackets can cause misalignment.
Obstructions: An obstruction in the sensor’s path is another common issue. Sensors send and receive infrared beams to function. The garage door won’t work if dirt or even small objects block the beam and prevent the sensors from seeing each other.
Wiring issues: Sensor operation can be affected by wiring problems. Intermittent or total sensor failure can be caused by frayed, broken, or loose wires.
Power supply issues: Last of all, power supply issues can cause sensor problems. The sensors won’t function if they’re not getting enough power.

Troubleshooting Main Problems

When your garage door sensors aren’t working, you can fix the problem more easily by looking at the root cause. Here’s a step-by-step guide to fixing garage door sensors:
  1. Check sensor alignment first: Sensor problems are often caused by misalignment. Start by looking at the sensors on either side of the door. Make sure they’re facing each other straight. If needed, realign the sensors.
  2. Check for obstructions: Remove anything that could block the infrared beam from the sensor. Look at the sensor lenses for any debris like spider webs or dirt. Gently wipe the lenses with a soft cloth to clear any accumulation. If you are not sure about how to clean the garage door sensors, call UAD now.
  3. Check wiring connections: Make sure the sensor’s wiring is good. Check for any disconnected, frayed, or loose wires. If you find any issues, call a technician for proper repair.
  4. Check the power supply: Make sure the sensors are powered. Check the garage door opener’s connections and power supply. A faulty transformer or tripped circuit breaker could be the reason for the lack of power supplied. If needed, replace the transformer or reset the breaker.
These troubleshooting steps will fix the most common sensor issues and get your garage door working again. If problems persist, consider calling a professional.

Summing up

In a nutshell, resolving garage door sensors is about being aware of common issues like blockages, misalignment, wiring errors, and power supply problems. By troubleshooting these areas, you can usually find the problem and get your garage door working again.
