What color should your garage door sensor lights be?

The color your garage door sensor lights should be depends on which side you are looking at and the brand of your opener, but there is a standard pattern for most brands. On most LiftMaster, Chamberlain, Craftsman, and Chamberlain-made openers, which represent the majority of homes, the correct colors are one amber, yellow, or orange light and one green light. The amber, yellow, or orange light belongs to the sending sensor that shoots the invisible infrared beam across the door opening. That color simply means it has power and is transmitting. The green light belongs to the receiving sensor on the opposite side. A solid, steady green means it is powered and successfully receiving the beam from the sender, which means the sensors are aligned and the path is clear. If the green is flickering, blinking, or off, it is not receiving the beam. Some brands differ. Genie often uses a solid red or green for the sender and a blinking or solid green for the receiver. Older Stanley or other systems may use red. Always consult your opener's manual, but for most systems you want to see solid amber or yellow on one side and solid green on the other side.

The correct color for your garage door sensor lights depends on your opener brand, but there is a standard pattern for the most common brands. For LiftMaster, Chamberlain, Craftsman, and Raynor, the normal healthy state is one solid yellow or amber light on the sending sensor and one solid green light on the receiving sensor. The yellow light means the sender has power and is emitting the infrared beam. The green light means the receiver is powered, aligned, and successfully getting the beam. If the green light is blinking, it is trying to tell you it is misaligned, dirty, or blocked. If the yellow light is off, it has no power. If the yellow is blinking, it may have a wiring issue. Genie and Overhead Door Intellicode systems often use a solid red light on the sender and a solid green on the receiver, or green on both. Some newer models use green blinking patterns to indicate different faults. Check the small label on the sensor housing itself, as many manufacturers print the color meaning directly on it. Regardless of brand, solid lights mean good, blinking or off means a problem that needs attention.
