My garage door won't open - What's wrong?

Common reasons garage door won't open.

1. Check to make sure the power supply to the garage door opener is working properly. Is it plugged in? You can even use an extension cord to plug the motor into and have the cord plugged into another outlet.
 2. Safety eyes are not communicating. On either side of the garage door about 1 foot or 2 from the bottom there are safety eyes that look like cameras. They face each other and prevent the door from closing if there is something in the way. Try wiping the lenses if dirt is present. Sensors have to also be in line with each other. Sometimes they can get accidentally kicked or nudged. A way to tell if their lights are not on. Adjust the sensors until they light up.
3, Springs are broken. These parts help move the door. When broken the motor has a hard time doing it on it's own.
4. Cables have snapped.
5. Your garage door motor and/or accessories have stopped working. See blog about servicing you motor for DIY.
6. You garage door is physically locked. Make sure the side lock or lock bar hasn't been engaged. Do not use the motor when garage door is locked as it will damage the motor and garage door section.

Until you get it fixed, you can manually open and close your garage door!
In the closed position, walk to the garage door from the inside. Along the garage door motor rail (above your head) there should be a red rope hanging from the rail. Pull on it until you hear a snap. The garage door motor no longer controls the door. You can open and close it as you need to.
