How To Bypass Garage Door Sensors Liftmaster

Garage door sensors are a common feature on many homes and businesses. They’re there to help ensure that your doors open and close safely, and they’re usually easy to use. But sometimes, something can go wrong. Maybe the sensor isn’t working correctly, or maybe it’s been tampered with. In either case, you may need to bypass the sensor in order to open your door. In this blog post, we will show you how to do just that. By following our instructions, you will be able to open your garage door even if the sensor is preventing it from happening normally.

What Are Garage Door Sensors?

Garage door sensors are a common security measure used to prevent unauthorized access to your home. Unfortunately, some people find ways to bypass these sensors, leading to unwanted visits from the garbage collectors or worse. In this article, we’ll discuss how garage door sensors work and what you can do if they’re preventing you from opening your garage door.

How Garage Door Sensors Work

A garage door sensor is a small device that attaches to the bottom of a garage door. When someone pulls on the garage door chain, the sensor sends a signal to the opener telling it to open. If the sensor detects anyone other than the owner trying to open the garage door, it will send a warning signal to the owner’s phone or computer.

If you’ve been having trouble opening your garage door despite using your normal security measures (garage keypad code, manual override), it’s possible that your sensor is not working properly. There are several things that you can check before taking any drastic measures:

1) Make sure that all of your cables are connected properly – sometimes debris can block connections between devices. Inspect everything from the sensor itself down to every connection in between.

2) Test each cable individually by manually closing and opening the garage door with each cable attached – if one cable fails but all others work fine, then it’s likely that something is blocking the signal from reaching the opener. Disconnect and check each cable one more time for any obstructions before replacing any

How to Bypass Liftmaster Garage Door Sensors

If you find that your Liftmaster garage door sensors are not working as they should, there are a few things that you can do to bypass them. The first thing to try is to reset the sensors by pulling down on the arm and pushing up on the sensor. If that does not work, you can try to reconnect the wires to the sensors. Finally, if those methods don’t work, you can try to disable the sensors by unscrewing the two screws located near each sensor.

What to Do If Your Garage Door is Not Responding to Commands

If your garage door is not responding to commands, there are a few things you can do to troubleshoot the issue. First, check the power supply to your garage door opener. If it’s getting power, but the door is not responding, there may be a problem with the command receiver or motor. If the power supply is working and the door still isn’t responding, try resetting the command receiver by holding down both buttons for two seconds. Next, try replacing the motor if it’s possible to do so. Finally, if all of these tests fail and you’re certain that there’s nothing wrong with your garage door opener itself, you may need to replace the garage door sensor.


Have you ever been stopped in your tracks by a garage door that wouldn’t open? Perhaps something was blocking the sensor, preventing it from sending an activation signal to the lift motor. If this is happening to you, there are a few things you can do to bypass the sensor and get your garage door opening again. Keep reading for instructions on how to do just that!
