3 Steps to Test & Assess Your Garage Door Sensors , Williamsport, Pennsylvania

Like any electronically wired device, garage door sensors may become susceptible to damage and consequently malfunction. If it happens to your device, you will first need to perform a few simple tests to diagnose the problem. Sometimes, garage door sensor issues can be remedied by following these three key steps.

How to Assess Your Garage Door Sensors 

1. Inspect the Sensor Beams

Your system’s sensor beams will either be located on the door or on the door’s rails, which can be found near the floor. To see if they’re functioning properly, you need to test them. However, due to safety concerns, you should never step directly in front of them. Instead, place a bucket or another object you won’t mind getting damaged in the lasers’ path. If the sensors are properly aligned, they will appear green and stop the door from closing. If they do not work, clean them with a microfiber cloth. 

2. Check the Wires

If you find any problematic areas, you will need to consult a professional to repair them. Only a licensed and insured professional should handle complex wiring systems.

3. Check the Operator Batteries

Don’t forget to check the sensor system’s batteries. Your handheld or car-mounted sensor device operates via batteries, which will eventually die. Fortunately, this is a simple fix—although one that’s easy to forget. If the car batteries do not correct the issue, there may be a problem with the springs or door itself.
