How To Bypass Garage Door Sensor?

Don’t fret. Everyone knows that an unresponsive garage door sensor is inconvenient.

A faulty or misbehaving sensor will stop the automatic doors from working. We all get irritated when this happens. 

This article explains how you can bypass your garage door sensor in simple and easy-to-understand terms.

How Does The Garage Door Sensor Work?

Garage Door sensors have been popular since the 1990s. It is mandatory to install safety devices with automatic garage doors to prevent accidents. 

The sensors’ primary function is to ensure the way is clear when the garage door is closing.

It is to make the way clear between the two photo eyes so that ‘they can see each other.’ Or, in technical terms, the infrared light between the two photo eyes remains uninterrupted. 

So what happens when there is an obstacle between the two photo eyes? Simple, the process will reverse, i.e., the garage door will open instead of closing.

Ways To Bypass Garage Door Sensor

Pressing Down The Garage Door Button

You can bypass your garage door sensors through the button installed in your house. Just press and hold down the wall button.

The garage door will start to close (go down) and will continue closing as long as you hold the wall button.

Now, if you release the button before the door is fully closed, the sensor will kick in, and the door will start to go up. 

Closing your garage door this way is only a temporary fix. It is strongly recommended to get your sensors checked by professionals.

You can also check out the simple and effective troubleshooting tricks given below.

Switch To Manual Mode

There may be a situation where the wiring is damaged, and your automatic garage door system stops working altogether.

In this case, switching to manual operation is the most reliable way. 

  • First, place strong supports or props (can also use a high shelf to hold the shutter) to hold down the sliding door when the chain is disengaged. Doing so will ensure that the door doesn’t go into a free fall.
  • Pull the manual release cord. The cord is usually bright red, and you can find it near the garage door motor. You’re disengaging the door from the door trolley by pulling the cord.

Tips & Tricks (Troubleshoot)

Check If The Sensor (Photo Eyes) Has Any Physical Obstructions

The photo eyes are the two main sensory components that automate your garage door opening and closing.

These two small infrared light sensors are set on either side of your garage door, at least 6 inches above the ground. 

Physical obstructions such as waste bins, buckets, garbage cans, gas cans, etc., can potentially block the infrared beam.

So the first step is to check and clear all items blocking the path between the two photo eyes.

Now you can try closing the garage door by pressing the remote control or the button in your house. 

Clean The Sensors With Microfiber Cloth

Since the previous troubleshooting trick doesn’t work for your garage door, let’s check if the sensors are blocked by dirt & debris.

An obstacle as small as the spider web can interrupt the infrared beam between two photo eye sensors.

Take out a clean cloth and start cleaning the sensors fixed on either side of your garage door.

Also, the cloth with which you’re wiping all that specks of dust & dirt is a microfiber cloth as it will not leave scratches on the lens of the sensors.

Re-test your garage door by pressing the close button on your remote. You can also do this by pressing the manual button installed in your house. 

Move on to the next step if you don’t get a positive result from this step.

Check For Loose Wires

The next step you need to take is to check the wiring status in your garage door system. An unstable power supply can be the primary reason for some garage doors not working correctly.

Check For Loose Wires

Check for any damaged or faulty wire, and the term damaged means wires that are frayed, burned, nicked, cracked, etc.

A broken wire is hazardous. If you find any, immediately stop the power supply to the garage door and replace the wire through a professional.

Check The Alignment

The photo eye sensor on either side of the garage door must be aligned correctly for the system to work. LED indicators on the sensors light up green when aligned perfectly. 

Your garage door may not close if the sensors are misaligned. A sensor is positioned inside a bracket (frames) fixed to the garage door’s left and right sides.

The height of the brackets is 6 inches above the ground. The sensors are fixed to brackets with nuts.

A bracket fixed to the garage door 1 feet above the ground

Tighten the wingnuts to the limit. Also, check whether the brackets are fixed tightly to the garage door.

Tighten the screws with a screwdriver. Doing so will ensure that the sensors are now set to the perfect position and aligned to each other.

When the sensors are correctly aligned, the LED indicator will flash with a solid green light (without flickering or blinking). 

Replace The Old ones With New Sensors

If the above troubleshooting methods don’t work, the problem may be related to the faulty sensor.

You can try replacing the sensors with new ones. Book an appointment with the local garage door repair workshop and get your sensors replaced.

You can also do this if you’re familiar with basic repair and maintenance. Just ensure that the door is closed before you disconnect the sensors.

Conclusion

Bypassing the garage door sensor is only a temporary fix until you get the problem fixed by maintenance specialists.

Also, you need to take extra caution when working around your garage door, especially if children and pets are in your house. 

Suppose you face a problem with your garage door due to a temporary glitch with the sensors.

In that case, it is recommended to use the troubleshooting tricks mentioned in this article. If the tips & tricks don’t work, you can temporarily bypass your sensors and quickly get your door serviced.

Frequently Asked Questions (FAQs)

Can You Bypass Garage Door Sensors?

Yes, you can bypass garage door sensors. The garage door is closed when the sensor detects the uninterrupted infrared beam. Holding down the wall button installed in your garage/house bypasses the sensors and forcefully closes the garage door.

How Do You Beat Garage Door Sensors?

The sensors (photo eyes) are on either side of your garage door. Brackets to the garage hold these sensors at least 6 inches above the ground. So the simplest way to beat the garage door sensors is to step high over the infrared beam. 

Can You Operate An Electric Garage Door Without The Sensors?

The answer is Yes. It is possible to operate an electric garage door without the sensors. But, you also have to accept the consequences of not installing detectors. Technically, a sensor primarily works as a safety device (critical safety feature.) It ensures that nothing is under the door when it is closing. Without sensors, it may lead to injury, especially when you have kids and pets. And in the worst-case scenario, someone or something may be crushed under the door and cause death.

How Do I Permanently Disable Garage Door Sensors?

You can bypass the sensors by pressing and holding the button installed in the garage until the door is closed. You can also disengage the sensors, switch to manual operation, and manually close and open the shutters.
