Limit Switch On Garage Door

A limit switch is a safety device that prevents a garage door from opening or closing too far. It is typically mounted on the door track and is activated when the door reaches the end of its travel. When the limit switch is activated, it sends a signal to the garage door opener, which stops the door from moving.

Limit switches are an important safety feature for garage doors. They help to prevent the door from crushing people or objects, and they can also help to prevent the door from being damaged.

There are two types of limit switches: mechanical and magnetic. Mechanical limit switches use a physical contact to activate the switch, while magnetic limit switches use a magnet to activate the switch. Magnetic limit switches are more common in newer garage door openers.

If you are having problems with your garage door, it is important to check the limit switches. If the limit switches are not working properly, the door may not open or close all the way, or it may open or close too far. You can adjust the limit switches yourself, or you can call a qualified technician to do it for you.

Here are some tips for adjusting the limit switches on your garage door:

1. Make sure that the door is closed before you begin adjusting the limit switches. 2. Locate the limit switches on the door track. There should be one limit switch for the open position and one for the closed position. 3. Loosen the screws that hold the limit switches in place. 4. Move the limit switches up or down until the door opens and closes all the way. 5. Tighten the screws to hold the limit switches in place.

Once you have adjusted the limit switches, test the door to make sure that it is working properly.

In addition to the limit switches, there are other safety features that you should be aware of when using a garage door. These include:

1. Photo eye sensors: Photo eye sensors are mounted on the sides of the door and emit a beam of light across the door opening. If the beam is broken, the door will stop moving. Photo eye sensors help to prevent the door from closing on people or objects. 2. Safety release handle: The safety release handle is located on the inside of the garage door. In the event of a power outage, you can use the safety release handle to manually open the door. 3. Manual lock: The manual lock is located on the outside of the garage door. You can use the manual lock to keep the door closed when you are away from home.

By following these safety tips, you can help to prevent accidents when using your garage door.
