Garage Door Is Lifted Off Ground

Garage door is lifted off ground.

Drums at the ends of the tube act as reels winding up the cables connected to the door. To help lift a heavy garage door the springs apply twisting force to the torsion tube. The photo eye sensor for a garage door opener is typically placed approximately two inches off of the ground. If that point is more than four feet or less than three feet above the ground you will need to balance the door.

The emergency release cord is the red rope that hangs from the garage door trolley. If the lift of the springs is greater than the weight of the door the springs will lift the door off of the ground. This brain can wear out in time so you could need a replacement. Smaller doors often have just one spring.

Since most photo eye sensors are placed at that two inch height most people know you can simply step high above the infrared light to bypass the system. If one of the photo eye sensors are malfunctioning it will begin to blink rapidly. When the door is in the closed position the release cord should be located near the front of the door. The most common problems with this system are broken springs or cables.

When the logic board wears out it can cause your garage door to close then open and vice versa without explanation. When the sum of the forces applied to the garage door due to the tension in the cables is close to the force on the door due to gravity a much smaller applied force human or opener is necessary to open the garage door.
