What Color Should the Lights Be On Garage Door Sensors — How do I know if my garage door sensor is bad?

Whatever garage door problem you are dealing with, this post is here to help. It will guide you to identify common door problems and how to fix them. You will also learn how to read and decipher garage door error codes.

Blocked safety sensors.

When the door won’t close and the light blinks 10 consecutive times, it is a problem with a blocked sensor. It could also be a misalignment or a faulty sensor. Look for a foreign material blocking the sensor beam and remove it. If this was the problem, the door will close and your problem is solved.

Safety sensor is misaligned.

After ruling out an item blocking the safety sensor beam, it is time to explore other problems. Next in your line of investigation should be checking for safety sensor misalignment. It is possible you bumped into the sensors when making a quick exit or entry. One of the sensors is the source of the beam and has a yellow light when it is on. On the other side is the receiving sensor, which has a green light when it is active. Both lights should be on when they are aligned. If any or both of them are off, then you are right to suspect misalignment. Realign the sensors until both lights are on and the door is working.

Damaged or broken wiring.

There are two common errors that indicate things are not alright with the wiring. One, up blinking once and down blinking once. It is an error for broken wiring. In other cases it could be telling you that there are no sensors installed. Two, one up blink and two down blinks. The message here is that the wire is shorting or it is installed in reverse.

Investigate any physical damage on the wire and repair it. Any loose wires will bring up the errors. Follow them up and tighten them at the loose points. Make sure the connections of the wires to the motor unit are done correctly. The white wires should be bound together and inserted into the white port of the motor unit. The white-black striped wires should also be bound together and inserted into the gray port of the motor unit. Also, check if the wires are connected in reverse and correct that.

You now know what color should the lights be on garage door sensors. The sender end should be yellow, while the receiver end should be green. If any of the lights are off, there could be a misalignment problem. Simply get the sensors in line and your door will open and close without a problem. Also, check and confirm the connections to be correct.
