Your garage door is one of the heaviest moving objects in your home, often weighing between 150 and 400 pounds. Without proper safety features, this presents a significant risk to your family, pets, and property. That's why understanding and regularly testing your garage door's safety reversal system is absolutely critical for every homeowner.
Modern garage doors are equipped with two primary safety mechanisms mandated by federal law since 1993: mechanical auto-reverse and photoelectric sensors (also known as photo-eyes). These systems work together to prevent the door from closing on people, pets, or objects.
The mechanical auto-reverse feature causes the door to immediately reverse direction when it encounters resistance while closing. This is your first line of defense against crushing injuries. The sensitivity of this system can typically be adjusted on your garage door opener, and it's crucial that it's set correctly.
Mounted about 6 inches from the ground on either side of the garage door opening, these sensors create an invisible beam. When anything breaks this beam while the door is closing, the door automatically reverses. You'll typically see a small LED light on each sensor—one should be green (indicating power) and one amber or red (indicating alignment).
We recommend testing your garage door's safety features at least once a month. Here's how to perform a thorough safety check:
1. Place a 2x4 piece of wood flat on the ground in the center of the door opening 2. Using your remote or wall button, close the garage door 3. When the door contacts the wood, it should immediately reverse direction 4. If the door doesn't reverse within 2 seconds, the auto-reverse needs adjustment
1. Open the garage door completely 2. Press the button to close the door 3. While the door is moving down, wave a broomstick or similar object through the sensor beam 4. The door should immediately reverse direction 5. Check that the sensor lights are illuminated and aligned
If your safety systems fail any of these tests, stop using your garage door immediately and contact a professional. Attempting to adjust these systems yourself can result in improper settings that may not protect your family adequately.
Signs you need professional service include: - Door doesn't reverse when contacting an object - Sensors are misaligned or not lighting up - Door reverses unexpectedly during normal operation - Strange grinding or clicking noises during operation
