This is one of the most common service issues your garage door can have. There are a myriad of reasons for this and we’ll explain the most frequent ones. There may be something blocking the safety beam, which will not allow the door to come down. 9 times out of 10, it is the photo eyes (i.e. Safety reverse system). It is a part of your garage door opener Fullerton which may have gotten bumped into and are out of alignment. The easiest way to tell if they are out of alignment is to look at the lights on the eyes themselves.
Why garage door is not going all the way down?
It will not go down if the eyes have been miss-aligned or are obstructed by something in your garage. If you have a garage door opener installed and when you press the button the door moves just a little and reverses OR doesn’t move at all in conjunction with the light on your garage door opener (up on the ceiling) blinking this is an indication of a safety photo eye issue.
The best thing to do is to check the indicating lights on the eyes themselves. The eyes are located at the sides of the garage door opening near the floor. The lights may be green, red, or yellow depending on the model. One on each side. The important point is if any are looseness and alignment. They need to be pointed directly at each other to receive a signal, then the light will stop blinking. When both lights are on and constant your opener should regain its operation. If not, and find you’re in need of service, give us a call immediately for options or services.
