Garage door have many mechanical moving parts in its system and over time some issues can occur. These problems can build up slowly eventually stop the door from closing.
It is highly important to know what can cause your garage door not to close and what exactly can you do about it.
Damaged safety sensor
When your garage door doesn’t close the first thing to check is the safety sensors, these sensors are the most important safety feature on garage doors that ensures safe closing. There are 2 sensors one on each bottom side of the door and one sends a laser beam to the other.
If the path is clear the LED light shows a green light and the door will close, but if something blocks the beam the door won’t close. Start by cleaning the sensors from dust that can block the beam, then check their alignment, if the sensors aren’t lined up correctly the door may not close.
The third issue and in order to fix it you will probably need professional help is a disconnected wire that can also prevent the door from closing.
Broken springs
The garage doors use industrial springs to balance the doors and lift them up. These springs are under lots of pressure and need and need enormous tension to work properly to work correctly, increasing their chances of snapping and break over time. When a spring breaks the door will drop down and wont move until the spring will be replaced.
Broken cables
Garage door cables run all the way along the door through the pulleys and connect to the springs. When the springs break the cables will likely snap too, so when replacing the springs take in account that you’ll need to replace the cables as well.
Damaged opener
If your garage door opener gets broken and stops working your door won’t close. The opener might fail because of loose wires or a short circuit. It can be hard to figure out the exact problem by yourself and it’s best to get a professional help.
Remote issues
Garage door opener connects to a remote control by radio signal and the remote get its power from a battery. If the battery is going low it might stop working if it’s out of range. Keep spare batteries on hand to replace them if needed.
