Hi there, I'm Maya. If your garage door is refusing to close, don't panic. Let's walk through a few simple checks. First, look at your photo eye sensors near the floor. If they're blocked or misaligned, the door won't close for safety. Wipe them with a soft cloth and make sure they're pointing directly at each other. Even a cobweb can trip them up. Next, inspect the tracks along the sides. Small objects, toys, or debris can get lodged in there and stop the door. Clear away any obstructions. Even a small piece of wood or a stray pebble can trigger the safety reverse. Now, look at the spring above the door. If it's in two pieces, that's a broken torsion spring. This is a job for the experts. Torsion springs are under high tension, so please don't try to fix this yourself. For more help, visit garagedoscience.com or use our homepage chat. We're here to help.
