No Green Light

[JerBear]

So I went to bind a New RFU to my TX and when I pushed the program button after the light started flashing...........it went dark and never turned orange and never turned green.  For the heck of it, I went ahead and tried to bind it to my TX when there was no light and my TX turned green like it binded.  Is my RFU bad since there is no green light?
