The garage door safety sensors are designed to ensure maximum safety for your garage door opener operation. The Genie garage door safety sensor kit (Safe-T-Beams) uses an invisible infrared beam across the opening of the door, the system detects any object passing through the infrared beam of light and automatically reverses the closing garage door. The Genie Safe-T-Beam system is required by US Law as of 1993.
However, the Genie Safe-T-Beam kit is self-diagnostic. If there is an issue or obstruction there is a series of garage door opener light flashes or small lights on the safety sensors to let you know what the issue could be (see chart below). If you are experiencing a garage door that will not close and a blinking garage door opener light you may have an obstruction of the Safe-T-Beam infrared light. If there is no physical obstruction you may have light interference. If the sun or another bright source of light shines into the garage door safety sensor lens it can cause a false positive and reverse the garage door. This can be a nuisance but good news, there is an easy fix available.
The Genie Version 2, Safe-T-Beam system (Model GSTB-R) has a lens cover that protects from alternative light interference, as seen in the picture below. This updated version should eliminate any false positive safety sensor signals. This is a very easy upgrade to your existing Genie garage door opener that should only take a few minutes to install. You can reuse your existing wiring and mounting locations. You simply remove the wires from the current Safe-T-Beam sensors and unscrew them from the wall. Then reconnect the wires and remount to the wall. The garage door safety sensor beams should still be lined up. If not loosen the mounting to the wall slightly and realign them by hand until both the red and green lights are on both sensors (one each on the left and right sensors themselves).
If an operating problem continues and you cannot close your door you can disconnect your Safe-T-Beams from the operator and hold down the wall control button until the door closes (remote and wireless keypad will not work without Safe-T-Beams).
You have just successfully upgraded your Genie Safe-T-Beam system!

@Arthur – 3 Flashes would indicate that the Safe-T-Beam needs to be replaced. The 3024 model would use the current Genie replacement Safe-T-Beams (part # 37220R). https://store.geniecompany.com/products/safe-t-beam-sensors
Hello, my name’s Arthur Ferreira , I am currently having a problem with the safety sensors on my genie door opener. The model number is 3024., currently the green light is steady and the red light flashes account is 3 flashes a pause then it starts over. According to the troubleshooting chart, it states that there’s a possible obstruction. There was no obstruction. I assume that the sensors are bad, I believe that they are the first generation the ones with the large lenses.
Any help would be appreciated. Thank you.
Arthur
@Ray Yeutter – The Safe-T-Beams should be installed one on each side of the garage door opening, and between 5 and 6 inches off the floor. The long blue blinking light indicates that the sure lock is turned on the wall console. Check the wall console and turn the lock off.
Question how far apart do the Safe-T-Beams have to be in order for my 2035 to work properly? I have them installed about a foot apart. When I started to program turnbuckle picked-up door then started to open I released the brown button now only the long blinks blue.
@ Kevin – A couple of things, If you had previously turned the light off from the wall console, this overrides the light feature. In that case, you would need to cycle the door again and wait for the light to go out automatically (about 4 minutes), then try to walk through the beams. If you have already tried that, then you can also unplug the unit that the lights do not turn on, then plug it back in while holding the DOWN (-) arrow button. This will toggle the feature on/off.
