Why is one sensor yellow and green?
You may have bumped a sensor out of position. Each safety sensor has an indicator light. The sending sensor, which has the yellow light, transmits the infrared beam to the receiving sensor, which has a green light. But you’ll only see the receiving sensor’s green light when the sensors are aligned and unobstructed.
How do you align a safety sensor?
Point the sensor away from the sending sensor, so that the light is completely off. Once the light is off, wait 10 seconds. Slowly rotate sensor back, aligning sensor with sending sensor, until it lights up green again. When you have a strong green light, put it back into the bracket and put the wing nut back on.
