How to Bypass Garage Door Sensors

Garage door sensors are an essential safety feature because they prevent the door from closing on a person or an object if they detect obstruction. However, what happens if they stop functioning and your door becomes permanently open?

You can attempt to disconnect the door’s sensors. However, doing so may render the door unworkable. It’s preferable to work around them until they’re fixed. This guide shows how to bypass garage door sensors easily.

How Can I Get My Garage Door to Work Without Sensors?

Garage doors might jam, but you can get on with your day if you learn how to get your garage door to work without sensors. The sensors in your home door won’t bother you if you follow these simple detailed steps:

Inspect the Garage Door for Possible Physical Obstructions

The garage door opener is sensitive enough to stop closure if it detects an obstacle. The easiest and quickest solution is to remove any barriers in the way of the sensors. Familiar sources of blockages include trash cans, gas cans, and even spider webs. Remove any obstacles and try shutting the door again.

If that doesn’t work, try wiping the lenses of the sensors with a microfiber cloth. They’d be back to normal working in no time if some dust or dirt were obstructing their efficiency. Another benefit of microfiber cloth is that it will not scratch delicate electronic parts like cotton or wool.

Check the Sensors Alignment

Your sensors won’t function if they aren’t correctly aligned. Check to see if this is the case before bypassing them. The LED lights on your garage door sensors are standard across all garage door opener brands. You may want to experiment with it a bit. However, the objective is for that light to turn on and remain solid.

LiftMaster will feature a single green light and single yellow light. Any combination of red and green, or even two reds, might be in Genie’s genie light. LiftMaster is similar to Chamberlain and Craftsman. Each linear device will display a green light, and one will display a red light.

Wingnuts hold the sensors in place. You may tighten the wingnuts all the way using your fingertips. This will ensure that they are appropriately positioned within the brackets. If the sensors include LEDs, they’ll glow green when aligned. Check that the garage door brackets are secure. If they’re loose, tighten them using a screwdriver.

Check the Wiring

If adjusting the sensor does not fix the problem, you should check your wiring. Sensors that aren’t responding may result from damaged or loose wiring. Inspect the sensor wires for signs of fraying, burning, or other damage. If you discover any, you should immediately disconnect the garage door’s power source to prevent further damage.

Reconnect disconnected wires. You can connect damaged wires back together. Wires behind the wall may require garage door repair. Bypassing the sensors is necessary if there are no physical signs of damage and the door is still not working.

Set the Door to Manual Mode

Separate the door-opening and -closing trolley from the automatic system. To achieve this, check for the manual release cord. It’s close to the garage door motor and bright red. Draw the cord downward. Now, you should be able to open and close the door manually.

If the door was jammed open, have someone hold it in place while you remove the props. Don’t forget to give your visitors advanced notice. They’ll have to be prepared to bear the door’s weight once the props have been removed.

Can I Disconnect My Garage Sensors?

Garage door sensors prevent the door from shutting if they detect an obstacle in the way. Sensors are a must-have for safety. However, they might impede the operation of an automatic garage door. The sensors on your garage door are likely faulty if the motor keeps running, but the door won’t close. 

Fortunately, most automatic garage doors have a manual mode that allows you to disable the sensors entirely. You can also disable the sensors entirely. However, doing so will render most garage doors dysfunctional.

To begin with, you can only bypass sensors via the wall button. Wait for the garage door opener’s light to flash before releasing the buttons. This will indicate that the system has been reset. Unfortunately, this is not the only permanent way. However, it will work with any brand of garage door opener. Having sensors that don’t work correctly isn’t a good idea. There’s a likelihood the opener doesn’t realize that there’s nothing physically obstructing the way. So you’ll have to try to convince it otherwise.

Chamberlain garage door openers add convenience and safety to a busy home hub. There’s a Chamberlain opener for every family’s garage needs and lifestyle. To disable the Motion Sensor, press the button on the sensor or use the adjacent switch on the door control. Using the opener lights as work lights requires disabling the motion sensor. The lights will switch off automatically if you work beyond the sensor’s range.

You must push and hold the wall button ( don’t press and release). Hold the wall button until the garage door touches the floor, then let go. The door’s sensors will automatically reverse their direction if you release the button before it touches the ground. You can then use the door’s opener to lock the door in the down position once you’ve closed it. 

You can turn off the Craftsman garage door opener’s sensor light by following these instructions:

  • When the garage door is closed, you can open it using the button on the wall or the remote control from your car.
  • Unplug the appliance from its socket.
  • You can remove the screws that hold the sensor light leads in place with a Phillips screwdriver if your model has screwed connections.

A smartphone app lets you monitor and control your Craftsman garage door from anywhere.

Does your garage door fail, stopping you from closing it when nothing is blocking the sensors? Holding the open/close button will bypass the garage door’s sensor. The garage door will be forced to close as a result of this. You need to press it and keep holding on until the garage door is entirely closed, as the sensors will automatically lift the door if you let go too soon.

Bypass Garage Door Sensor Using 555 Timer

You can use the 555 Timer in oscillating (astable) mode to remove the garage door opener from the door. In this case, an IR LED is powered by the switching output of a 555 timer. By doing so, you can toggle the LED on and off. Pulling the emergency release cord will disconnect the garage door from the opener. The door trolley features a spring lock to which the emergency release wire connects.

Garage Door Sensors Not Working

Modern garage doors feature sensors to prevent closing on an individual or an object. Each end of a garage door comes equipped with a sensor. The primary purpose of sensors is to identify any obstruction in the door’s path. If there’s one, the sensors will restrict the door from closing, preventing harm to the door or car.

All garage door sensors experience this issue, regardless of brand. Sensor failure typically results from the same underlying issues. Some problems are minor, and you can address them on your own. Other issues are more complicated and require a qualified technician.


I hope you find this guide on bypassing garage door sensors helpful. Bypassing the sensors can be useful if a short solution is required before the repairs can be completed. You won’t need specific skills or pricey tools.

You should take this step only if all other possible solutions cannot fix the problem. Don’t do it, as it could injure children and pets in the path of the closing garage door. If you’ve already bypassed your garage door sensors, tell us how it went. Your helpful tips would be greatly appreciated.
