If your garage door won’t close, reverses, or the opener light flashes, there’s a good chance your safety sensors (photo eyes) are misaligned. The nice part is that alignment is usually a quick fix—often under 5 minutes. This guide shows you how to align photo eyes safely, what the sensor lights mean, and how to stop the…
Garage Door Won’t Close Unless I Hold the Wall Button: If your garage door refuses to close with the remote or keypad—but it will close when you press and hold the wall button—that’s not random. On many garage door openers, that behavior is a built-in safety feature often described as a sensor override. In plain English: the opener is…
Garage Door Safety Sensor Lights Off: If you look at your garage door safety sensors (photo-eyes) and both lights are completely off, the opener may refuse to close the door—or it may close only when you hold the wall button (on many models). When both sensor lights are out, the issue is usually not “alignment.” It’s more often…
Garage Door Sensor Sunlight Problem : Does your garage door close normally in the morning, but in the afternoon it suddenly starts acting up—reversing, refusing to close, or flashing the opener light? That “works sometimes” pattern is very often caused by sunlight glare hitting the safety sensor (photo-eye). It’s especially common on garages that face west…
If your garage door starts to close but then immediately reopens, it’s frustrating—and it can leave your garage unsecured. The good news is that this problem usually comes down to one of two things: Those two issues look similar at first, but they leave different “clues.” This guide shows you how to tell which one you’re…
When your garage door won’t close and the opener light starts flashing, it’s almost always the opener’s way of saying: “Something is triggering the safety system.” In most U.S. garage setups, the #1 cause is the safety sensor (photo-eye) system—either the beam is blocked, the sensors are dirty/misaligned, or sunlight/glare is interfering. The good news: many fixes are quick and…
A blinking green light on a garage door safety sensor (photo-eye) is one of those problems that feels bigger than it is. Most of the time, it’s not a “broken opener” situation—it’s the sensor system telling you it can’t reliably see the safety beam. In this guide, I’ll walk you through the most common causes and the easiest…
If your garage door won’t close and you notice a blinking amber (yellow) light on one of the safety sensors, you’re dealing with a very common issue: the photo-eye safety beam isn’t being completed consistently. The good news: in many cases, the fix is simple (alignment, cleaning, or an obstruction). This guide walks you through safe troubleshooting steps you can…
