5 Possible Reasons Why Your Garage Door Isn’t Opening

by | Jul 12, 2022 | Garage Door Repair Anaheim

Your garage door not opening could be caused by many things. If the opener doesn’t work or the door only opens part way, you might need to replace some or all of it. 

Here are some of the most frequent reasons for a garage door not opening.

1) There’s Something Wrong With the Power Source 

Your garage door opener needs power to operate. If there’s no power coming from your outlet, it’s the most likely cause for a garage door not opening.

First, check if the breaker or fuse has been tripped. If the breaker was tripped, reset it. If the breaker or fuse was not tripped, unplug the door opener for about 30 seconds to reset its circuit. Plug in the opener and test the opener again.

2) The Photo Eye Is Blocked

Photo eyes are sensors that are installed on the garage door and the garage opener. If the photo eye is not able to detect movement, the door will not open.

To test the photo eye, push the button on the remote and watch if the beam of light goes down and if it detects the light. If the beam of light does not go down, check if the photo eye is blocked. Move the garage door opener and check if the beam of light goes down. If it still can’t detect the light and go down, the photo eye is blocked and needs to be replaced.

3) The Cables Are Broken

The important parts of a garage door opener are the door tracks, springs, and the cable. If the cables are broken, the door will be unable to move. If the cables are broken, the door will be able to move, but the door is not able to close.

To check if the cables are broken, manually open the door and watch if the cables move. If the cables do not move, the cables are broken and need to be replaced.

4) Limit Setting Needs Adjustment

A limit setting determines whether the garage door can be opened once it’s reached a certain point. It’s the device that determines how far the door will extend when you open it manually or when the opener is activated.

If the limit setting is adjusted too high, the door only opens half way. If this happens, adjust the limit setting to a level that will allow the door to open all the way.

5) The Torsion Springs Are Broken

Torsion springs are the springs that run along the shaft of your garage door opener. If the torsion springs are broken, they need to be replaced.

The garage door will not be able to open if the torsion springs are broken. To check if the torsion springs are broken, manually open the garage door and watch if the springs are working. If the springs are broken, the garage door can open, but the springs will not be able to pull the door back up.


If your garage door opener is malfunctioning or the door doesn’t open all the way, call a professional to take a look at it.
