Let’s get started…

3 Simple Tricks To Bypass Garage Door Sensors When It’s Not Working

Trick 1: Inspect The Sensor Light Path For Possible Obstruction

This is a very common issue of your garage door sensors that react strangely when you try to open or close your garage door through its remote.

Point out that your garage door sensors are so sensitive even spider webs, or a small thin piece of paper can prevent the garage door sensors from opening or closing your garage door. 

This is why, thoroughly check the path of your garage door sensor all the way from left to right and clean dust particles, debris, and plant leave from its path. 

Trick 2: Stand Against The Sun Ray To Close Your Garage Door

If your garage door faces the Sun most of the time a day then this could also be a reason that your garage door sensors are not working. 

You can check the if sensors work or not by standing against the sunlight. You have to stand in such a way that your body prevents the sunlight from hitting the sensors. 

At the time when your shadow prevents direct sunlight from hitting the sensors, use your garage door remote and try to close the door. 

If you don’t have remote control then tell someone to close the garage door through the wall button. If the door is closing it means, you are ready to trick or bypass your garage door sensors.

After Successfully Trick The Garage Door Sensors, It’s Time To Troubleshoot Them 

The next morning, I woke up worried free because last night I successfully bypassed my garage door sensors and was able to close my garage door and locked it. 

I slept well because my garage door is closed so there was no chance of burglary in my garage. 

Now it’s time to troubleshoot the garage door sensors.

1. Clean The Garage Door Sensors

Sometimes dust and debris accumulate on the surface of sensors and an opaque sensor is enabled to transmit and receive signals properly. 

To fix it, take a piece of cloth and wipe all the dust from the surface of both of your garage door sensors. 

2. Align The Sensors Properly

If a garage door sensor from one side of your garage door misaligns with the garage door sensor of another side then due to a signal loss, your garage door will not open and close through the wall switch and the remote.

3. Disengaged Or Faulty Garage Door Sensor Wires

After checking thoroughly if you found that there is no obstruction on the path of garage door sensor lights, and the sun rays are not covering the sensor’s light then the problem could be due to faulty or disengaged wires. 

To solve this problem cut the damaged part of the wire and peel its cover off and joint it again, to the connector. 

4. Replace The Damaged Sensors

If the wires of the sensors are in good condition then the garage door sensors must be faulty and need a replacement. You can buy them either online or from the local shop near you. 

Read the user manual and install them correctly.
