Diagnostic Codes via blinking Call button
4-flashes = Door Close Fault: A call was latched for 10 seconds, but the hoistway floor showed to be open.
The computer control panel shows LEDs 1, 2, and 4 as not lit, which corresponds to:
1: Gate closed and Emergency Stop OK
2: Door Closed
4: Fault contact OK
Any ideas on what part might need to be replaced and how difficult it would be to replace? Images of the conrol panel below.

The white sticker box is the door lock (we have one of these mounted on door frame (not on elevator car itself) and there is one on each floor. The orange sticker item is the gate switch (mounted on top of the elevator car). Oddly, bot have the same part numbers on them, 3152415. I noticed that this PN was part of a recall, but not sure if that means I can get a free replacement. https:/
I have this page from an entire booklet of schematics.
These look to be the actual parts listed on the EMI Porta website. It seems unlikely both would have failed at the same time.

I would definitely find out if the door locks are recalled or not. Why they would have used a plastic latch in the first place is beyond me. My assumption is your door lock is part of the recall since the label says 2008 and that is in the time period of the recall.

This is my analysis, which I believe to be correct, but I could be wrong...
LED_1 is for circuit GE, LED_2 is circuit DC, and LED_4 is circuit FC. These are located on the schematic you posted in schematic zone 5C and 5D.
The way I read the schematic is that for GE to be happy, DOOR_CLOSE_1, DOOR_CLOSE_2, DOOR_CLOSE_3, DOOR_CLOSE_4 all have to be closed. Basically all the entry doors on all the floors. This is the door switch on each floor. For example, if you only have two floors, there are only DOOR_CLOSE_1, DOOR_CLOSE_2.
Further, you can see DC has an input from GE and its own sensors. So, if GE isn't right, DC cannot be right regardless of the sensors specific to DC.
And, you can see FC has an input from DC and its own sensors. So, if DC isn't right, FC cannot be right regardless of the sensors specific to FC.
So, my conclusion is that one or more of DOOR_CLOSE_1, DOOR_CLOSE_2, DOOR_CLOSE_3, DOOR_CLOSE_4 aren't right. Most likely something is out of alignment. If could be a bad switch, but that is less likely.
