Welcome. My name is ***** ***** would be glad to assist.
Please elaborate on the situation.
What is happening with the door opener?
Will not open or close?
Details will help to evaluate what the problem may be and what is needed to correct.
Let me know and we can continue,
Need to get the sensors connected back to the opener wiring and then see if one or both eyes have the LED lit.
Then we can see which direction to go on the troubleshooting.
You may remember, if so post the original findings, please.
Let me know what the status of the sensors is when all connected.
It is unknown what type of voltage is used for the sensors, as they do no switching, as is usually thought No publications for what voltage a manufacturer applies to the sensors, the sensors output a variation frequency to the logic board in operation.
Everything works off the same power supply and if the opener works with the wall button to over ride the sensor failure, the issue will be in the sending eye , as it has to illuminate before the receiving eye can function.
You can ohm out the wiring to the opener head from the sensor with them disconnected at each end and if the wires are good, a new set of eyes will be needed as they only sell them in pairs.
Since they do not publish a detailed wiring diagram for the openers, the easiest way to determine if the eyes go directly tot he power supply or the logic board
is to verify where the wires go on the black side of the photo eye terminals.
Most go to the Logic board, and that is what I would suggest, but not knowing exactly yours, I suggest to double check.
Looking at the parts for the opener, there is only one board, the other is a transformer.
Transformer can be checked if it has a labeled marking on the voltages.
The logic board can also do other things with that signal and why it would be the high suspect.
