Garage Door Sensor Yellow Light Issue – How to Fix It

Garage door sensor yellow – A yellow sensor light on the garage door sensor is a sign that the safety reverse sensors on your garage are not in alignment. Your garage door won’t shut until the sensors are aligned. Begin by cleaning the lenses on both sensors, and then make adjustments to each sensor to ensure that they align perfectly with each other.

Garage door sensors are usually located just a few inches off the ground, with one sensor on each side of the garage door.

They use “photo-eye” sensors and a “photo-eye” system. It is simply said, they shoot an invisible, infrared beam that stretches from one side of your garage door towards the opposite.

When you push the remote control to close the garage doors, an alert is transmitted to the sensors. They are designed to stop the garage doors from shutting against somebody or something.

The garage door will only open only if the invisible beam of infrared traversing the door is not interrupted. Sometimes, these sensors fail to function properly.

The primary sign of a sensor that is malfunctioning is the obvious yellow light from the sensor and also the garage door not closing or trying to close. It is quickly opening. This is followed by an illuminated light coming from the ceiling control box.

Clean dirty lenses

The first step to take when you notice the yellow light on the garage door‘s sensor is to take care to clean your lens.

Because these sensors are close to the surface of your garage, They can be exposed to all sorts of grime, dirt, and cobwebs.

The most simple thing to do is to simply use a paper towel that has been wet with a bit of water, then thoroughly clean the lens straight.

You could also apply a mild cleanser such as Windex or similar, which won’t leave streaks behind. Make sure not to get the lens wet.

While you’re there, make sure you cleanse the sensors on the opposite end of the door as well to add some extra oomph.

Realign sensors: Garage Door Sensor Yellow Light Issue

The sensors for your garage that are misaligned are most likely to be the cause of the yellow light on your LED and the reason the garage door won’t shut.

Both sensors have to be directed toward one another and at exactly the same angle.

It is possible to use a screwdriver to remove the bracket which holds the sensor in its place. Once it is free, proceed to place it exactly the way you’d like.

Once you are sure that the sensor has been placed in the proper position and the bracket is tightened, tighten it up, and secure the sensor in position.

If you do not have a screwdriver at hand, however, you may be able to adjust the sensor by applying some pressure to it.

Certain models contain a wing nut that holds each sensor. In this case, make use of your fingers to loosen and tighten the nut.

When you are sure that your sensors are perfectly aligned to one another, You can then try to shut the garage door.

If this doesn’t work, then continue reading.

Replace or reconnect the sensor wires

If cleaning the lenses of each garage door sensor and changing them wasn’t enough to work, then you must be attentive to each sensor’s wire.

You’re looking for signs of fraying or damaged wires. Make sure they’re all properly connected and in a snug way.Sometimes, these wires may be pulled away or damaged over time. This could cause a short to your garage door’s wiring.

If you’re not really skilled and you’re noticing these indications of damage to the wiring, I’d suggest calling an expert to help with repairs.It’s quite dangerous working with electrical wiring and electricity. Certain things are worth the cost.

Professionals have the necessary tools to complete the job and will be able to pinpoint precisely what is wrong and what can be fixed faster and with less risk than you can.

Remove objects

Another reason that could be behind your malfunctioning garage door sensor could be that something has gotten in the way.

Any obstruction to the infrared beam that runs between these two sensors can cause your garage door to open up.

Sometimes it is clear, such as a ball or bike that clearly blocks the way. It’s also less evident. The sensor could actually be on a bookcase or a toolbox that’s placed beside the sensor, which seems to be hidden; however, it isn’t.

If you’re still experiencing issues with your sensors, be extra cautious about moving everything and anything remotely close to each sensor. Remove anything within a foot of the sensor and then close the garage door once more. Try to determine if this fixes the issue.

Call Customer Support for Garage Door Sensor Yellow Light Issue

This will depend upon the garage door opener brand that you own. However, when you’ve come to the wall, and the garage door remains damaged, I’d suggest giving the garage door experts an appointment.

You can also enter the name of the brand that you use for your opener in Google, then “support,” and find the number.

Replace the sensors on your old ones

If you’re still seeing the yellow light on your garage door sensor even after cleaning the lenses, realigning them, reconnecting/replacing sensor wiring, moving objects out of the way, and contacting support, then it’s time to buy new sensors.

There are many possibilities for why your old sensors stopped working. These could be due to the time of use, excessive usage or exposure to extreme weather, and so on. No matter the reason, the sensors you have are old and need replacement.

For a start, head online or visit your local home improvement store to purchase new sensors. Check that the new sensors will work with your garage door opener. After you’ve received the new garage door sensor, you’ll have to put them in place. For installing your new sensors, take these steps.

Installation of the door track:

  1. The curved arms from the bracket along the edges of the track. Then snap them into place so that the sensor bracket sits aligned with the track.
  2. The bolt should be inserted into the slot on the sensor.
  3. Install the bolt into the hold inside the bracket for the sensor and secure it to the wing nut. The lenses on both sensors must face each other. Be sure that the lens isn’t blocked by the bracket for the sensor.

Installation without prior wiring:

  1. Connect the wires through both sensors to connect the opener for the garage. The wire is connected to the ceiling and wall by using staples.
  2. Remove 7/16in (11mm) in insulation off of each wire. Cut the wires in two. Twist the black and white wires. Twist the black/white wires.
  3. Connect the white wires to the white terminal of the opener for garage doors. Connect the black/white wires to the terminal in grey on your garage door opener. To connect or remove those wires out of the terminal, pull into the tab using the screwdriver tip.

Pre-wired installation:

  1. Cut off the end of the sensor’s safety reverse wire. Make sure that there is enough wire that can be able to reach the wires that were installed away from the wall.
  2. Separate the security reversing sensor wires and cut 7/16 inch (11mm) of insulation on each. Select two pre-installed cables and strip 7/16 inch (11mm) of insulation on each. Make sure you select the same color wires for each sensor.
  3. Connect the wires pre-installed to the sensor wires using wire nuts. Make sure the colors are the same as the sensor. For example, the black wire will connect to the yellow wire, and the black/white wire will join in purpling.
  4. For the garage door opener, Remove 7/16 inch (11mm) of insulation off each of the wires that you previously selected for the security reverse-reversing sensors. Connect the wires of similar colors.
  5. Connect the wires that are connected to the safety sensor wires in white onto the white terminal of the opener for garage doors. Connect the wires connected to the black/white security sensor wires into the gray terminal on the opener for garage doors.


If you’re experiencing an orange light on either or both of the garage door sensors, don’t fret, this is very typical. The most effective way to correct this issue can be to wash the lens of both sensors. Then, ensure that they’re perfectly aligned with each other.

They must be of the same height from the ground and in the exact same direction, directly at one another. If this doesn’t fix your issue, you need to be sure to examine the wires coming from the sensors.

Make sure that the wires you are using aren’t frayed, damaged, or broken in any manner. Sometimes, they are accidentally pulled away or ripped. Also, remove everything and everything within one foot of each sensor away from the. Sometimes, these objects can disrupt or block the beam of infrared, which is being transmitted between two sensors, which can cause the sensors to fail.

I hope you find this useful, and one of these troubleshooting techniques helped you solve your issue. If not, try and find the contact number for support, and then give experts a call.

If nothing else works, then you may need to purchase a brand new set sensor for your garage doors.
