There are two ways to open garage doors either manual or automatic. Automated garage doors are machines that run off sensors and electricity. This sounds very technical, but really it means that anything and everything can affect the function of your garage doors, from dust and dirt to insects and even the cold weather. Even the wrong switch can make a difference to your garage door and whether it jams or remains working correctly. But it’s still important to work out what the issues are so that you can look into getting them fixed quickly. If you are looking “why is my garage door jammed?” then you need to look at the common reasons it could be happening and your garage door getting jammed.
