Nov 9, 2017 at 8:28 comment added Trevor_G The green led also looks like it was replaced, it may be in backwards in the photo.
Nov 8, 2017 at 22:36 comment added mguima Could you put a photo of the back of the PCB?
Nov 8, 2017 at 22:25 comment added Trevor_G Ya that is fine, but your schematic is wrong.
Nov 8, 2017 at 22:21 answer added Trevor_G timeline score: 4
Nov 8, 2017 at 22:17 comment added Jeffrey Drake @Trevor It's hard to see, but the pictures show that both LEDs are facing the same direction.
Nov 8, 2017 at 21:59 comment added Trevor_G D3 must be backwards though or it would never light with D2 in parallel
Nov 8, 2017 at 21:52 comment added Jeffrey Drake @Trevor I also added a photo of what the inside of the panel looks like... The circuit boards are literally just for the function of showing whether a door is opened or closed.

Added another image to show how the boards are used.
Nov 8, 2017 at 21:39 comment added Jeffrey Drake @Trevor I added the pictures.

Added images of the LEDs and the bottom side of the circuit board.
Nov 8, 2017 at 20:58 comment added Trevor_G Something is definitely wrong with your schematic... Recheck the diode polarities.. or post a pick of the board. D4 and D8 cant both be pointing the same way.
Nov 8, 2017 at 20:27 comment added Jeffrey Drake @PeterBennett Okay, I have to physically go to one of the doors, so I can see it and draw it out, I will add it to my drawing when I am able to get that done.
Nov 8, 2017 at 20:23 comment added Peter Bennett Please show the door switch and power supply connections on your drawing.
Nov 8, 2017 at 19:56 comment added Jeffrey Drake @PeterBennett it is hooked up to a NO-NC switch that the door activates & deactivates on the closed side of the door. So, when the door is closed the green LED (left side) should light up, and when it leaves that closed switch, the red LED (right side) should light up. I hope that answers your question.
Nov 8, 2017 at 19:24 comment added Peter Bennett What is this board connected to? How does it know if the door is open or closed?
Nov 8, 2017 at 19:19 comment added Jeffrey Drake Okay, the far right side (I think) is positive power. The inner right side gets daisy chained to other circuit board terminals in the same place. The inner left side can also be daisy chained to other circuit boards in the same place. The far left is (I think) negative... Again, I'm not sure of any of that, but I'm doing the best I can.
Nov 8, 2017 at 19:06 comment added Wesley Lee It does look like the circuit board to me. What are the terminals connected to? If I have time I'll come back later and try to organize the schematic a bit.
Nov 8, 2017 at 18:53 comment added Jeffrey Drake @WesleyLee I think I did that right... I'm not an expert, but that looks like the circuit board?

Nov 8, 2017 at 18:20 comment added Ignacio Vazquez-Abrams It's just a general feeling. You'd need to draw out a schematic to be certain.
Nov 8, 2017 at 18:19 comment added Jeffrey Drake Could you possibly elaborate? I'm not too savvy when it comes to this stuff... Which section looks like a logic gate? Is it AND or OR?
Nov 8, 2017 at 18:17 comment added Ignacio Vazquez-Abrams Looks like maybe a diode gate. Primitive stuff, but effective.
