6 Most Common Reasons Why Your Garage Door Won't Open
#1 Your Photo Eye is Blocked
Most garage doors from the past 15-20 years will have a photo eye which detects if a person or object is blocking the door from lowering all the way. The photo eye will be about 4-6 inches off of the ground for most doors, with an eye that is about the size of a pea. The photo eye shoots a laser across the length of the garage that if interrupted will cut off the signal used to lower and raise the door.
Check both that the cord attached to the eye is not cut or damaged, occasionally a rainstorm or leak can affect the photo eye and damage it.
Sometimes dirt and dust can clog the eye and block it from shooting its lazer beam, so a thorough cleaning with a tissue can sometimes dissolve this issue.

#2 Your operator's power source is disrupted.
Sometimes people will unplug their power source and then wonder why their garage door opener fails to work. Sounds ridiculous I know, but it does happen very often. Make sure that your garage door opener is plugged into a working outlet. Outlets sometimes go out without warning, so you can check to see it the outlet is working by plugging another working electronic device into the outlet to see if the plug is working. Also check your circuit breaker, fuse or GFCI.

#4 Your Garage Door Cables Have Snapped
Oftentimes when a torsion spring breaks on a garage door, the garage door cable will snap under the immense amount of energy that is released with the break. Sometimes the cable will cause damage to a vehicle or wall, and if a person happens to be in the way of the cable it can cause serious harm. If you cables have snapped you should call a professional to help you repair the damage and get your garage door back to working order.
#5 Your Sensitivity is out of Adjustment
This can happen to a newly installed garage door or an older one, if the sensitivity is set too low or high the opener will not open due to the fact that it will not sense that the door has enough weight or too much. You can test your sensitivity on the opener with your manufacturers directions in the documentation. You can adjust the close force and limit switch to the right levels and you should be good to go!
