Your garage door is the largest moving object in your home, weighing anywhere from 150 to 400 pounds. When operating properly, it's completely safe. But when safety features fail or maintenance is neglected, garage doors can cause serious injuries. Here's what every homeowner needs to know to keep their family safe.
Modern garage doors include several safety mechanisms required by federal law since 1993:
This feature reverses the door's direction if it encounters an obstacle while closing. There are typically two types working together:
Mechanical reverse: The door reverses when it physically touches an object Photoelectric reverse: Invisible light beams near the floor detect objects in the door's path
Both systems should be tested monthly to ensure they're functioning properly.
The photo-eye sensors are located 4-6 inches above the floor on either side of your garage door opening. To test:
1. Start with the door open 2. Press the close button 3. While the door is closing, wave a broomstick through the light beam 4. The door should immediately reverse direction
If it doesn't reverse, the sensors may be misaligned, dirty, or malfunctioning. Do not use the door until this is fixed.
This tests the mechanical safety reverse:
1. Place a 2x4 flat on the ground where the door meets the floor 2. Close the door 3. When the door contacts the 2x4, it should reverse immediately
If the door continues pressing down on the 2x4, the force settings need adjustment. This is a critical safety issue.
An unbalanced door puts strain on the opener and can indicate spring problems:
1. Close the door 2. Disconnect the opener (pull the emergency release cord) 3. Manually lift the door halfway and release 4. A properly balanced door should stay in place or move only slightly
If the door rises or falls significantly, the springs need professional adjustment.
Contact a professional immediately if you notice: - Frayed or worn cables, Rust on springs, Door shaking or vibrating excessively, Gaps between door sections, Door coming off track, Grinding or unusual noises, Door not reversing when it should
While monthly tests are important, annual professional maintenance is equally crucial. Our technicians will:
- Inspect all safety features, Check spring tension and balance, Lubricate moving parts, Test and adjust force settings, Inspect cables, rollers, and tracks, Ensure proper sensor alignment
If someone or something is trapped under the garage door: 1. Pull the emergency release cord to disconnect the opener 2. Manually lift the door (it may be heavy) 3. Seek medical attention if needed
Never attempt to repair springs, cables, or other high-tension components yourself. These components are under extreme pressure and can cause serious injury or death.
