1. Visual Inspection:
- Check for any visible damage to the safety sensors or their cables. Look for loose connections or broken parts.
2. Alignment Test:
- Position a small object (like a piece of cardboard) in the path of the safety sensor beam, near the bottom of the door.
- Close the garage door and observe if the door reverses as it should.
- Repeat the test on the other side of the garage door.
If the garage door reverses when it encounters the object on both sides, the safety sensors are likely properly aligned.
3. Obstruction Check:
- Check the area around the safety sensors to ensure there are no obstructions blocking the sensor beams. Dirt, leaves, cobwebs, or even pet hair can interfere with the sensors.
4. Clean the Sensors:
- Clean the lenses of the safety sensors using a soft cloth and a glass cleaner. Dirt or debris can affect their performance.
5. Manual Test:
- Manually press and release the button on each safety sensor to check if the door reverses when the sensors are triggered.
If you try all of these methods and the sensors don't seem to be working properly, it's possible that they are faulty and may need replacement.
If the safety sensors still fail to function after these steps, or if you're uncomfortable troubleshooting the issue yourself, it's best to contact a professional garage door repair technician to diagnose the problem and perform any necessary repairs or adjustments.
