Garage Door Sensor Blinking Red

The red blinking light occurs when something is blocking the safety beam or sensors are not correctly aligned. An object may bump the sender or the receiver out of position, or a wire may have come close. Homeowners can fix the situation by inspecting the bracket or tightening a screw in the blinking sensor.

The LED on your garage door plays an essential role in informing you of the status of the sensors. The indicators show different colors while in operation or when they malfunction. For instance, the exterior LED indicator will blink red when you try to close the door if the sensors are out of alignment, damaged, obstructed by an object, or covered by dirt.

Often, the green light indicates that the sensors are working correctly, while the red light indicates an issue with the sensors and requires the attention of the garage owners.

Does Your Yellow Garage Light Need To Work

Since 1993, there has been a federal law requiring all automated garage doors to have a sensor system that can prevent accidents from happening.

Those sensors are there so that your garage door can be alerted if someone falls underneath the door as its closing. In the past, garage door accidents happened fairly frequently with small kids as a result of parents being unable to notice them crawling near the door.

Not having working garage door sensors on a motorized door is a federal building code violation. In most HOAs, council members can also write you up if you dont have working sensors. So, even if you dont use the motorized garage door opener too often, its absolutely worth a fix.

Besides, most garage door opener models wont even work without the sensor beam being on. So, theres that issue, too.

Safety Sensors Are Getting Weak

Every garage door opener is equipped with a sending sensor and a receiving sensor. The sending sensor shoots out an invisible beam which needs to make a connection with the receiving sensor to complete the circuit which allows the garage door opener to close. These sensors are only active on the down cycle and have no effect on a garage door opener when it is going up.

The most common double car garage door is 16 or 18 feet wide. Over time, the sending sensor can get weak, making it harder to align the safety sensors over a large span. If you feel this is your problem, you need to replace the pair of safety sensors as they have circuit boards inside like the motor head. These circuit boards can get weak over time, causing intermittent issues when closing the garage door.

Why Does My Garage Door Not Close And Light Flashes

How to troubleshoot Genie garage door sensors

You can never be worry-free if your garage door wont shut because it means that the security of your home is compromised. If this is the case and you see that the sensor lights are flashing, it could be one of a few issues either the lock button is engaged, or the sensor units have a problem.

First, you need to confirm if the sensors were installed correctly. Then check the openers lights. If you notice that they blink two times, the lock button is on.

To resolve this, you need to disengage the lock button on the door control. Operating your door via remote controls is impossible when the lock feature is engaged. You can only manipulate the door using the door control.

Heres how to turn the lock button off. On the door control, press the lock button, after which the sensor light will blink two times, indicating that the lock feature has been disengaged. Now try operating the door with remote controls and see if the door will shut.

Subsequently, if you notice that the lights flash ten times upon examination, this suggests an obstruction or misalignment problem with the sensors. The infrared beam is thrown off, meaning that the units do not see each other in the case of misalignment.

Troubleshooting A Garage Door That Wont Close

Are you having troubles with a garage door which simply will not close? Garage doors comprised many moving parts and a single faulty component can prevent your garage door from closing. Here are the most common garage door problems or breakdowns, that will cause a malfunctioning door to not close:

  • Broken cable or cable off the pulley.
  • Garage door off the tracks.
  • Misaligned, bent or obstructed tracks.
  • Broken hinge.
  • Bent or damaged sections.

If the garage door system has been thoroughly inspected and the mechanics are not damaged, try to operate the garage door with both remote control and wall console. If neither of them works, its more than likely that youre looking at faulty garage door opener which its sensors are being obstructed, misaligned, or not connected properly. Garage door sensors utilize infrared beam of light to detect the presence of objects, a similar technology to that found in remote controls and burglar alarm systems. The sensors are designed to detect the presence of a car or object , but defective sensors could cause a garage door not to close, as the garage door opener programmed to do so if it believes that something is blocking its path.

How Do I Adjust My Garage Door Sensors

Before you attempt to realign the sensors, you should try adjusting the photo eye lens manually and see if it lights up. If not, follow these steps:

  • Cut the power off: while you wont be working on any electrical wiring, its definitely safer to align the sensors with the power off to prevent accidental activation of the garage door opener system.
  • Locate the sensors: on most modern garage doors, the safety sensors are located near the tracks on both sides of the garage door, usually not higher than 6 inches above the floor.
  • Loosen the screws: once youve located the sensors, use a screwdriver to loosen both wing nuts slightly in order to be able to reposition the sensors. Make sure not to loosen the screws too far or remove them completely.
  • Level the sensors: carefully align the safety sensors so that their lenses point towards each other and start glowing steadily. You can also try tying a string between two sensor brackets tightly and use a level to check if the alignment is correct.
  • Tighten the nuts and test: once youve aligned the sensors and achieved a steady glow of the LED lights, use your screwdriver to tighten the nuts in place. Turn the power on and use your remote control to check if the door closes properly, and youre done.

What Color Should Craftsman Garage Door Sensor Lights Be

Both Craftsman garage door sensors should display steady light. However, the color dispensed by each LED sensor is different. The receiver sensor shows a green color while the transmitter sensor is orange.

How Do Garage Door Sensors Work

Garage door sensors work when electric energy is transformed into an infrared beam of light. The same infrared beam of light comes from one side of the garage door units that are placed up to 4-5 inches above the floor level. This helps in sending the beam light to a central receiving unit on the other side of the garage door.

Therefore, be it a mechanical or photoelectric garage door, both of them need to work perfectly well and give you the best of services required of them.

Peradventure both sending and receiving parts of the garage door are not well aligned you will see a signal showing on the door sensor with a light showing on the wall control unit of the sensor installed very close to the entry point of the door.

Garage door sensors work with the open and close buttons seen on the control panel of the sensor. They are all connected to the beam light, they can be wired or wirelessly controlled, but all the components that help the garage door sensor work properly have wire connectivity.

Check The Garage Door Sensors Wiring

Sometimes your garage door sensor will malfunction due to wire damage caused by wear and tear from regular use, pests, or the elements. When this happens, on most models, your sensors light will flash orange instead of red.

Inspect the wires that connect the sensors to the terminal on the openers back. Check that the cables are intact and for any wires that are twisted or broken.

Untangle any tangled wires that you find, and examine the wires to ensure they are correctly connected to the terminal. The white wires should be connected to the white terminal, and the black and white wires are connected to the gray terminal.

Inspect the wires for any chew marks or signs of tampering. Also, look for water damage. Water can short your sensors and cause them to malfunction.

If the wires are damaged, you may need to replace them. Unless you are a skilled electrician, we recommend you hire someone to replace the wires for you. Otherwise, you risk getting electrocuted!

A professional can also check the rest of the automatic garage door system for other parts that may need repair.

Damaged wires may cause your automatic garage door system to work inconsistently or incorrectly. For your safety, disconnect your garage door from the opener to avoid damage to your property and prevent any injuries.

You can reconnect your garage door to the opener once the wires have been replaced and the sensors are working correctly.
