How do garage door safety sensors work?
Garage door safety sensors are sensitive to bangs and bashes and tend to lose alignment when something hits them hard. When determining whether they need to be replaced or just adjusted, you need to look at all the options. When you examine how these sensors work, you realize how intricate they are. A sensor is basically an electronic beam of light that sees things in its path and when blocked, reacts by stopping or reversing its action. These are all safety measures fitted into your garage door safety sensors.

Can you put your garage door sensors in the ray of the beam?
For safety reasons, a person should never put themselves in the ray of the beam to test the sensors. Use something that doesn’t matter if it gets damaged, such as an old container. Modern-day garage door safety sensors are usually LED and if the sensors are aligned correctly with the two beams connecting, they should light up green. Take a clean cloth and very gently wipe them in case they have accumulated dust or residue of some sort. Do not handle them more than necessary or you might well put them out of alignment.
What does a garage door sensor do?
In general, garage door sensors block the door from closing if there is an object nearby.
Why is my garage door sensor not working?
A common cause of a malfunctioning garage door sensor is lack of power supply. Look for small LED lights on the sensors.

If you see the amber LED turning on and off during the wiggle test this indicates you might have an issue with the wire nuts and should resecure the wires together after turning the power off.

You will find one sensor with an amber color LED which should always be on and this sensor sends the sign also known as the sender. The sensor across from the sender has a green LED which is only on if the sensor, also known as the receiver, is receiving a signal from the sender. Check the LED lights and both the sender and receiver to make sure they are on.
Step 1 -Where to Find The Sensors
- Your garage door safety sensors are found in one of two places. They are either on the door itself or on the rails of the door close to the floor area. You will most often find them mounted to the rail of the door.
Step 2 – Do The Garage Door Safety Sensors Work?
- If you come home and the garage door fails to open normally, it is time to look at the sensors. As their position is vulnerable (one on each side of the garage door), they are frequently subjected to bumps and bruises.

Modern-day garage door safety sensors are usually LED and if the sensors are aligned correctly with the two beams connecting, they should light up green. Take a clean cl...
Step 4 – Checking The Wires
- Sometimes the sensors get knocked or banged causing a wire to snap, come adrift, or merely cause a slight disconnection. If it’s a slight disconnection, this could cause your garage door safety sensors to work intermittently. If the wires are broken, you can use a soldering iron to fix them after unplugging the unit from your outlet.
Step 5 – If All Else Fails
- Remember if the garage door works on the wall switch, then the fault definitely lies with the sensors. Check the sensor operator batteries. Generally, people tend to forget that the door operator kept in the out car runs off batteries. Replace them and see if that works.
