Questions & Answers


My red light keep blinking on my sensor. Door goes half way down and stop and go back up

Asked by Julius January 25, 2021

It sounds as if you may have an issue with the safety beams or wiring on your unit. Here are a few things to check. Both of the safety sensors should be lit and solid one red, and one green. If one or both of them are out it is an indication there is a wiring issue. You will want to first be sure the connection on the beams and head are secure. If only one light is off, please disconnect the beam that is not lit and connect it to the wiring on the side that is lit. If the beams lights up replace the wiring to the beam on the non-lit side, if not replace the beams. If both are out you will want to short wire the beams directly to the head you will disconnect the beams and wire them to the terminals on the head that they are currently connected to using two short pieces of 18-20 gauge bell wire. If the beams lite up you will need to replace the wiring, if not replace the beams. If one of the beams is blinking please be sure that the lenses are clean, clear from obstructions and properly aligned. Please count the blink pattern and let us know what the results are. Also, check to see if you can press and hold the wall console in to get the door to close. If you cannot, try removing the safety beam wires from the power head, then try constant pressure on the wall console to close the door. If you still cannot, once the safety beams are not wired, this may be a problem with the circuit board. You can also call 1-800-354-3643 for further assistance.

Door stops and reverses for no reason. I replaced door sensors at bottom and this didn't fix the problem. Any ideas?

Asked by tcamp January 10, 2021

Hi tcamp- If the door is going all the way to the floor and opening back up, this could be that the force needs adjusted, and may not have anything to do with the Safe-T-Beams. If you would like troubleshooting assistance to help determine the issue, you can contact Genie customer service at 1-800-354-3643.

Are these two sensors interchangeable? Can you put either one on either side?

Asked by tcamp January 4, 2021

Yes they are BUT be careful about sun location's effect on the receiver because strong sunlight will make it not work correctly.

Are these 2 wire?

Asked by Craig December 18, 2020

Hi Craig! Yes, these use 18 to 22 Gauge door bell type wire.

Will these work with a 16' span door opening?

Asked by Mark December 16, 2020

Yes, they will.

Do these sensors absolutely have to be 6" from floor? Can they be 8" up?

Asked by bryansimpson October 6, 2020

Between 5 and 6 inches is what is the standard recommended height for installing for safety. Anything higher could allow low lying objects to be undedected and the door could close on them.

Will this work with any garage door opener?

Asked by Fourndog October 2, 2020

I would say most. There may be some older units I have not used

Will this work with a Wayne Dalton 3018 garage door opener? The existing ones (Wayne Dalton 25211...

Asked by nash September 30, 2020

These should work. I replaced my sensors and the old ones were rectangular, very similar to yours. I have loaded a picture that shows the old style on one door and the new. style on the other door.

Do you have a diagram how to wire two new replacement sensors? I can’t seem to find anything to help.

Asked by Zach September 26, 2020

Hi Zach- Here are the instructions:

I have a new 7055 Genie garage door opener and have installed the T-beam sensors. I have no lights on the sensors.

Asked by Mark September 25, 2020

The lights are on if they have power and are correctly aligned with each other. If they can’t connect the doors won’t work.

Perfect replacement for the older style sensors. New mounts used same holes as old style so replacement was a breeze. Now, someone please tell me why these fail?

This product has been installed and is working fine. I like how it is easier to see the red and green lights on the sending and receiving units. I would have given the sensors a 5-star rating if the Sensors detached from the mounting frame as the printed instructions indicated and if the holes for the mounting screws had lined up better with those in the earlier model I was replacing.

hard winter replacement
Easy enough to break, built to be near the floor, hard to locate to a safe place for the switch. The new style is much improved over the older type which slides off the bracket.

Easy fix if you are handy
After 15 years of trouble-free service, my 1997 Safe-T-Beam sensor intermittently prevented the door from closing. The red LED on the STB transmitter module would blink 4 times, pause, and repeat, indicating the transmitter was not sending pulses to the receiver module across the garage. You can override the STB system by pushing and holding the wall control button until the door is completely closed, but it is much more satisfying (and much safer) to fix the problem. You can certainly replace the sensors using this kit. Or, armed with a Phillips screwdriver and a soldering iron, you can easily fix the transmitter instead of sending it to the landfill (I mean recycle it, of course!). In my case, the problem was the solder holding the IR LED (infrared light emitting diode) pins to the circuit board inside the transmitter module had cracked, probably from 15 years of thermal stress. Follow these steps to fix this problem. 1)Remove 2 screws to open the transmitter module. 2)Remove the screw holding the circuit board in place. 3)Remove the circuit board and locate the IR LED, which is the clear plastic bulb pointed at the lens. 4)Flip the board over and locate the IR LED mounting pins. The cracked solder is easily visible with a magnifying glass. 5)Re-solder the pins to the circuit board. 6)Reassemble the module and enjoy 15 more years of service!

My door would not go down and would only go up. I wasn't sure if the eyes where the problem but bought these guessing the old ones where the cause. Installation was easy and it solved the issue. Hopefully I'll get many more years of use out of the doors again before needing replacement.
