Your garage door is the largest moving object in your home, weighing anywhere from 130 to 400 pounds depending on the size and material. With that much weight in motion, the safety reversal system isn't just a convenience.it's a critical safety feature that could prevent serious injury or even save a life.
Modern garage doors are equipped with two primary safety mechanisms mandated by federal law since 1993: photo-eye sensors and mechanical auto-reverse. Understanding how each works is essential for proper testing.
Photo-Eye Sensors are mounted near the floor on either side of your garage door opening. They project an invisible infrared beam across the doorway. If anything breaks this beam while the door is closing, the door immediately reverses direction.
Mechanical Auto-Reverse is a backup system built into the opener itself. If the door encounters resistance while closing.such as hitting an object.it should automatically reverse.
The Consumer Product Safety Commission recommends testing your safety reversal systems monthly. Here's our professional-grade testing procedure:
1. Open the garage door fully 2. Place a 2x4 board flat on the ground in the center of the doorway 3. Press the close button on your wall control or remote 4. The door should reverse before touching the board 5. If it doesn't reverse, clean the photo-eye lenses and realign them
1. Open the garage door fully 2. Place a 2x4 board flat on the ground in the door's path 3. Temporarily block or disconnect the photo-eyes (consult your manual) 4. Close the door using the wall button 5. The door should reverse upon contacting the board 6. If it doesn't reverse within 2 seconds of contact, adjustment is needed
Photo-Eyes Out of Alignment: The most common issue is misaligned sensors. Look for a steady green LED on both sensors. A blinking light indicates misalignment.
Dirty Lenses: Dust, cobwebs, and debris can block the infrared beam. Clean both lenses with a soft cloth monthly.
Sun Interference: Direct sunlight can overwhelm the photo-eye sensors. Consider installing a sun shield if this occurs regularly.
Sensitivity Adjustment: If your door doesn't reverse properly, the opener's sensitivity may need adjustment. This is best left to professionals as improper settings can be dangerous.
While monthly testing is a DIY task, certain situations require professional attention. Contact Richland Garage Doors if your door fails any safety test, the door reverses randomly, sensors won't stay aligned, or you're unsure about any aspect of the testing procedure. Your family's safety is worth the call.
