How to Cheat Garage Door Sensors | A Step By Step Guide

A garage door sensor prevents the car from entering or exiting your home. If you’re running late for work and don’t have time to put everything in the house, a good practice is to close all windows before driving out of sight because it will add an extra layer of protection against burglars trying to break into your vehicle. This article will teach you how to cheat garage door sensors, which many workers look for. Fooling the garage door sensors is very simple.

Press and hold the button on the wall until the moment the door hits the ground. Then it would help if you released the button. It would help if you did not release the button before the door hits the floor. Releasing it earlier will reactivate the sensors causing the door to reverse.

The trouble with Craftsman Garage door sensors, can I bypass?

We will know we have faulty detectors when they or the garage door motor blink also if the garage door does not close. If you want to avoid these sensors on automatic garage doors, you have to configure them manually. Another alternative is to disconnect the sensors completely. However, doing this will not work on most garage doors.

How to Check If Your Garage Door Safety Sensors Work?

How to Cheat Garage Door Sensors

If you want to check, the sensors take an object you normally use as a cardboard box. Then in the sensor line, locate the box and try to close the door. So if it intercepts with the box and moves back the door, it means that it works well.
Now, if it continues, it means that there is a fault. Gates are used at the entrance of the garages to preserve our lives. Opening and closing whenever necessary. These go up or down when a button is clicked. Keyboards are also used with certain combinations.

In this way, our properties are protected. But when these garage doors don’t open or close properly or break, the opposite happens.

A misaligned sensor is a common problem with a garage door.

Operation of garage doors

Garage doors can often break down, and to solve this situation on their own, you have to know how they work. Security sensors in residential automatic garage doors have been used since 1993.

Its use has been so that it does not close on objects or people. These sensors are the ones that will signal if there is an obstruction in your way before you close up shop for the day. Sensors work as a key safety feature on automatic garage doors.

By sensing an obstruction in the closing door along the way, the sensors reverse their direction. They are returning the door to its open position. Security is compromised if these sensors don’t work. So doing this kind of feature test is very simple. And if the sensors are found to be faulty, you can figure it out yourself.

How to Bypass Your Garage Door Sensors Permanently?

To avoid them permanently, do the following steps:

  • You must do the cleaning.
  • Make sure the sensors are in the right place.
  • Check the wiring conditions.
  • Try to get him to close the door.
  • If you do not close the door, you must leave it open.
  • Place the door in manual mode.
  • Open it manually.

How to Permanently Bypass Your Garage Door Sensors


To avoid the sensors, you can disconnect the garage door opener. If you need to disconnect the garage door from the opener, you must pull the emergency release cable.

You will find a spring lock on the door cable to which the emergency release cord or wire is attached.

What Should You Know About Garage Door Sensors?

Its primary role is to find possible interference when closing a garage door. That is why when wanting to close a door and the sensors detect an obstruction, they will not let it close.

This is how they work, guaranteeing your safety, avoiding possible damages to your property.

How do I know if my garage door sensor is bad?

Sensor failure indicators

There are ways to find out the causes of the failure of the garage door safety sensor. Certain indicators allow us to recognize the fault in a garage door sensor.

When the problem has already been identified, it will be when you decide how to solve it.
Three indicators help us to know the fault in the sensors.

To verify if the door sensors are faulty, we can follow these steps:


LED light: When you see the exterior LED light of the door sensors blinking understand the sensor is bad.
Red light: if we see red lights, it means that the sensors have no alignment.


Greenlight: if we observe green lights, it means that the sensors are working correctly.

Dirty lenses: Sometimes to fix the fault in the sensors, we will only need a clean cloth. This is because the sensor lens retains dirt, causing blockage of visibility by dirt or cobwebs. In this way, the sensors stop working as the view of the garage door opener is not clear.


Dust always accumulates in a garage: For this reason, you must be careful to keep the area clean. On the other hand, we must constantly clean the sensors.

Cables in poor condition:

The sensor system has a series of cables whose function is to connect it. These can wear out from regular use, weather, or from pests.

Even some tools or instruments can influence the wear of the cables.

You should check the wiring for damage from water, chewing, or any other indication of damage. If it is found that they do have marks or damage, you must replace them immediately.

Repeat the cardboard box operation, as you can see above.

In this way, you will verify the solution or hire the services of an expert.

How to Use the Manual Release for Garage Doors?

When you want to open the garage door without difficulty, we must follow the following steps:

  • The door must be in the down position.
  • Pull the emergency release cable.
  • Move the door manually and return it to the downward location.
  • Pull the emergency release cable to the door.
  • Proceed to connect the springs to the opener carriage.

Replace Sensors

If you follow all the steps and find no faults in the white wire, sensor, lens, or LED light, you should replace the sensor.

This is because it is simply a defective sensor, and you can buy it in a store. You can also purchase it online, then proceed to install it.

Would you please verify that you purchase the correct sensor style and brand? Everything is very simple, but if you do not think you can do it, asks for the service of experts.

As you can see, a garage door sensor is a very simple mechanism.

Install a door opening sensor

The opening sensors for garage doors are instruments that have a great advantage. This refers to its installation, which is very simple.

To install it, you should only take into account placing it in parallel.


Level the magnet and reed switch. This procedure should not have any drawbacks. The essential thing is to fix it.

Here are the steps to follow to install the sensor:

  • The sensors come with an adhesive by default for their installation. However, some sensors come with screws that allow you to fix them to the wall.
  • Make sure the magnet and the blade switch are parallel and level. Leave a minimum space between the two. This is so that the necessary circuit can be formed. The circuit won’t work if they are far apart or are not parallel.
  • If there is no circuit, the sensor will not work.
  • This means that before installation, we must ensure that we meet these requirements.
  • If the doors and the frame are out of level with each other, proceed to place the magnet in the frame. The sensor will be placed on the door.
  • As said the sensor has a self-adhesive that comes by default to clean the installation surface. Avoid using oils during cleaning.
  • Fix it well.
  • If you receive false alarms at the end of the installation, the sensor is not working correctly.
  • This may be because the installation was not done as it should. It could also fail to level, or the batteries are worn out. In the case of wireless sensors, the alarm center may be too far away.

Frequently Asked Questions

Can you bypass the garage door sensors?

Yes, you bypass it by disconnecting the garage door opener from the garage door.

Do both sensors on the garage door be green?

Typically, each sensor will have a light. One will have a green light to indicate that the units are on. Moreover, the other will have a red light to indicate no blockage between the sensors and that they can see each other.

Why is my garage door sensor yellow?

The infrared beam is sent from the transmitting sensor with a yellow light to the receiving sensor, which has a green light. It would help if you always turned on the yellow transmitting light on the garage door sensor.

Can you bypass the sensors on a Chamberlain garage door opener?

The sensors identify things in the path of the closing door and will not enable it to close while those objects are there. Garage door openers can be circumvented, despite safeguards in place to prevent the security system from malfunctioning.

Why is my garage door sensor blinking green?

Blinking green sensors typically indicate that the door has identified a malfunction or a safety concern. Thus it serves as a warning to the homeowner that there is a problem. The blinking opener lights indicate that the safety sensors are n to working well.

What color should lights be on the garage door sensor?

Checking if the external LED light blinks when you close the door is an easy method to detect if your garage door sensors are out of alignment. Green lights show that the sensors are operational, but red lights indicate that you need to align the sensors.

What does it mean when one garage door sensor is yellow and the other is green?

Probably, you may find a sensor out of place. Each safety sensor has an indicator light. The infrared beam sends a signal from the transmitting sensor. It is a yellow light that receives the sensor, which has a green light. The yellow transmitting light on the garage door sensor should always be on.

Bottom Line

Now, you already know how garage door sensors work, how to avoid thread of them, detect their faults. Also, how to verify each fault, install them, among other aspects.

In this way, by yourself, you can install the door sensor in your garage without complications. If a problem arises, you will also know how to solve it.

And if you don’t feel satisfied with it, you know that the next step is to call a professional. Although we know that it will not be so because there is no trouble installing sensors.

You can see negative-going pulses if you gaze across either sensor when the beam presents damage, the voltage switches to supply voltage. It is simply a detector for missing pulses.

All openers are different, but most of them are likely. When the door is open, you want to observe when the beam presents an obstruction. However, you only need to know when the beam is not working well because nothing can enter to break the beam if you close the door. If you like, you may connect an end-of-door travel switch to the relay. A scope shows pulses flowing toward the ground but not to the ground while the beam is unbroken.
