Garage door sensor Yellow is normal.

Is your garage door sensor yellow? If it is that’s ok, it should be. On LiftMaster and chamberlain garage door openers you will have one yellow( or amber) and one green colored led light on your safety sensors. The yellow light signifies the sending eye and the green light is the receiving eye.

Green senor is flashing

If your sensors are both lit up and solid they are functioning normally. If the green light is flashing they are misaligned or the sending sensor ( the yellow one) has a wiring issue or has gone bad. You should start by attempting to adjust the sensors to ensure they are properly aligned. Just loosen the wing nut and tilt the sensor up or down to make sure they are straight. You will know you have fixed it when the light stops flashing.

Led Lights are not lit up

If neither light is lit up then there is a wiring issue or the sensors have gone bad. If this is the case you may need to replace the sensors or the wiring.

Is a yellow garage door sensor keeping my door from opening?

No! Your garage door sensors do not control the opening of your garage door, they only keep it from closing when something is obstructing them. If you are having a problem opening your garage door it could be anything from a faulty remote to a broken garage door spring.

What does Liftmaster say about your garage door sensors?

Unfortunately there is a lot of bad information on the internet. We have even seen top results on google telling homeowners that a yellow garage door sensor means the sensors need to be replaced. That is completely wrong and incorrect information. If you are ever having issues with your garage door and you believe the opener is to blame, consult your owners manual or a trusted professional first.

If you do not have a copy of your owners manual, just google your model number ( this can be found on a sticker on your garage door opener) and the word manual and you can download a pdf copy.
