Will Garage Door Work Without Sensors?

Thinking about the other ideas, you can also disable garage door sensors on your own by setting the door on manual mode. For that, first of all, make sure that the door is closed. Open doors may cause a certain amount of crashing if the door spring is damaged. If the door is already open and is stuck, then you can also prop the door up with 2x4s. If you don’t have it, you can use any other sturdy item like a shelf in its place. 

This way you can avoid any accidents that may cause by the falling of the door. The 2x4s or any sturdy item are used to prop up the door can prevent it from slamming shut, even when the door spring is damaged. After that pull down the red cord that is usually located next to the garage door motor. It will disconnect the trolley from the automatic opening system and then you will be able to open or close the garage door manually.

Remove the 2x4s and do the opening or closing process manually. You may need someone’s help if you need to close the door manually. Pull the cord towards the garage door motor to open the door. Once you get rid of 2x4s, lower the garage door to the closed position. Be slow and stay careful. If you are not confident or face some troubles doing this process alone, ask your friend to help you.
