Testing your Garage Door Automatic Reverse

With the weather being so warm and pleasant this time of year, it’s a perfect time to get outside and take care of any issues around the exterior of your home. One spot that rarely receives the attention it deserves is your garage door.

Automatic reversing mechanisms are critical to the door’s proper operation, and one that is malfunctioning can severely injure someone caught in the door’s path, or worse. The weight and pressure exerted by a garage door can be very dangerous to people in the path of the door, especially children, which is why it is so important to make sure your auto-reversing mechanism is working properly.

What is an auto-reversing mechanism?

Even if you aren’t acquainted with exactly what this mechanism is, you’ve likely seen it in action. When you close your garage, and it stops part way down and re-opens, that’s your auto reverse at work.

This safety feature works in two separate ways. The door opener motor has sensors built into it to detect resistance and is designed to stop and reverse if it meets a certain threshold automatically. Additionally, there are two infrared sensors mounted just above the ground on each garage door roller track, and if an object is blocking the beam between the two sensors or if something breaks the beam during closing, the door will not close.

Testing your automatic reverse

One of the most popular methods for testing both reversing mechanisms on a garage door is to place a roll of paper towels on the ground in the path of the door. If the door causes the cardboard tube in the center of the roll to deform, it’s applying too much force before reversing direction. Alternatively, you can try the same test using a 2-inch block of wood. If the door does not immediately reverse upon hitting the wood, it is applying too much force.

Repairing a malfunctioning auto-reverse mechanism can be something as simple as realigning the sensors at the bottom of the door track, or as complex as replacing the entire opener motor. Repairs on a safety feature like the auto-reversing mechanism should always be handled by a professional like those here at Absolute Overhead Door.
