How To Wire Garage Doors Without Sensor: 3 Step By Step Guide

How To Wire Garage Doors Without Sensor

Garage doors are common doors in the home, chances are you have one, especially if you have kids and pets. Your garage door sensor stops the door’s closing operation once it senses motion or hindrance. However, your sensor can be faulty, and the door will be stuck halfway or totally.

You can wire your garage door without sensors by installing the opener, connecting the wires, and testing the work. A garage door without a sensor either runs manually or closes without attention to objects in its path. The manual operation of the door is not ideal, especially for houses with kids, aged, disabled people, or pets.

If you are looking for a guide on how to wire your garage door without a sensor, you have come to the right blog. This article will explain a step-by-step guide to wiring your garage door opener without a sensor.

Are Sensors Required On Garage Doors?

Yes. Sensors are an important safety device for garage doors. A garage door without a sensor can cause home accidents. In most advanced countries, all garage doors must have a sensor. There are other garage door safety devices, but the sensor is more popular. 

Considering the garage door’s weight (between 150 to 400 pounds), it is hazardous to install your garage door without a sensor because it can crush anything it falls on, including kids and pets. 

Is There A Way To Bypass Garage Door Sensors?

Yes, bypassing your garage door sensors is possible. You can do that by turning on the manual mode on your door opener, removing the sensors, long pressing the garage door button, or taking out the sensor. Misalignment, dirt, or obstacle on the door’s path are some of the reasons to bypass your sensors.  

Basically, homeowners install garage doors for security purposes. However, a faulty sensor will hinder the garage door’s smooth operation, resulting in a malfunctioning door. A malfunctioning door can distort your schedule and come in between your activities. It can also be dangerous. 

Bypassing a garage door sensor is an easy task, but you must know that it is hazardous and not safe. Bypassing the garage door sensor is not similar to fixing or repairing it. You must consider your safety and make it a temporary solution.

To bypass your garage door sensor, you must first be certain that the sensor is the problem. Some sensors with LED lights will blink and make beeping sounds, when they are faulty. Before bypassing, troubleshoot the sensors to check for any possible problems by:

  • Checking If The Sensor Is Still In Place

A sensor that has gone out of position will not work well. This may be the problem with your sensor, and you may not need to bypass it. The sensors can be found at the base of the garage door and are tightened with wingnuts. 

 If the sensors are loosened, tighten them until it gets back in position. 

  • Cleaning The Sensor

Dirt on the lenses of your sensor will hinder it from functioning. Pick a clean cloth and clean the dirt or dust so the sensor can work again. If it is still not working, check the next point.

  • Checking Wiring Connections 

If the sensors’ wires are destroyed or loosed, the sensor’s functionality will be affected. To fix this, put off the power supply and change the wires. I advise that you call an electrician to fix it. 

  • Clearing All Obstructions From Its Path

Another troubleshooting idea is to ensure that all items or obstacles are cleared. Your garage door will not close if the sensor senses any objects. You have to do this before bypassing. 

If, after a thorough check, the door is not closing, you can proceed to bypass it. There are several ways you can bypass garage door sensors. 

Way One: Turning On The Manual Mode

The first way to bypass your garage door sensor is to turn on the manual mode on the door opener. This will mean that door operations – opening and closing, will be done manually. 

Look for a red-like rope – the release or emergency cord, on the garage door motor and drag it down. By that, you have detached the door from the automatic Opener and can now open and close the door manually. 

Caution: Before starting this process, ensure that your door is closed but if it is stuck mid-way or totally, get a partner to hold the door because you are about to get a bang once you detach the door from the Opener.

Way Two: Remove The sensors

Another way to bypass the sensor is to locate it and remove it. The sensor is often a small plastic; it comes with LED lights. Loosen the screws on the sensors to remove them.

Warning: Ensure you put off the power supply before removing the sensors.  

Way Three: Long Press The Garage Door Button

Even though there is no item on your door’s path, the sensor can still sense that there is still an obstruction. Hence, it will not close. You must long-press the garage door (wall) button until it closes. Do not release the button until the door closes.

After this, you need to call a technician to fix the door sensor, as pressing the door button is a temporary fix and may be inconvenient. 

Way Four: Reconnecting the Sensors

In this method, you will have to cut the sensor wires on both sides and take them out. After that, reconnect the sensors directly to the motor house, and let them face each other. This way, your sensors are properly positioned to work well.

Note: Reconnecting and realigning the sensor will cause the door to close continually. That halting function will be altered when someone or an item gets in the way.
