Where are the sensors on a garage door opener?
The infra-red sensors that facilitate your garage door opening system are placed on either side of your garage door/doors, and they stand approximately six inches off of the ground. If, for some reason, the sensors are malfunctioning, one of the sensor lights will start to blink.

What color are my garage door sensors supposed to be?
They are usually black in color and will have small green or red LED lights. 3. Monitor the LED lights on the photo eyes watch for blinking lights. When one of the eyes is not working, or if there is an alignment problem, the LED lights will not be lit or will be blinking.
Why won’t my garage door sensors light up?
If the LED is not glowing steady, this means there is an open or shorted wire. Replace the wire currently connected to the sending sensor. If you have replaced the wiring and the sensor is still not glowing steady, replace the safety reversing sensors. Use the remote control to close the garage door.
Why do I have to hold the button down to close my garage door?

Why won’t my garage door close when its hot?
When the weather gets hot, the metal on the bracket and rails expands in a way such that the safety sensors become misaligned. When it’s hot and the door doesn’t operate, check to see if there are any blinking lights on the sensors. If lights are blinking, the sensors are misaligned, and need to be fixed.
Do both garage door sensors need to be green?
Color of the Sensor
The transmitter is likely to be a green light while the receiver should be green colored. It’s important to note, however, that not all sensors have different color lights. A garage door tip is to check on the sensors to see if anything is blocking them.

What do IR sensors detect?
An infrared sensor is an electronic instrument that is used to sense certain characteristics of its surroundings. It does this by either emitting or detecting infrared radiation. Infrared sensors are also capable of measuring the heat being emitted by an object and detecting motion.
Where do garage sensors go?
