I recently replaced both the inverter board and the main control board on a built-in KitchenAid refrigerator. After the installation, everything powered on correctly — the refrigerator started running, and the compressor engaged as expected.
However, I noticed one connector that I couldn’t find a place to plug in. I thoroughly inspected the wiring and confirmed that everything else appeared properly connected. The only issue now is that the ice maker’s optic board isn’t receiving power, and the infrared beam isn’t turning on.
To troubleshoot, I even replaced the optic board with a new one, but the issue persisted. Since I installed the new service board for the main control, I suspect the unplugged connector may be related to the optic system, but I can’t find where it should go.
At this point, I need help identifying where this connector belongs. Ideally, I’m looking for:
A wiring diagram or schematic for this model
A clear image showing where the optic board connects
Or a detailed video walkthrough that covers this specific issue
I’d appreciate any guidance so I can complete the repair and make sure the customer is fully taken care of.

This is a double wall oven with the 2 appliance managers. According to the tech sheet, if error code F1E0 appears then the UI must be replaced. I replaced the UI and the error code is still present. The tech sheet also mentions to check 14 VDC from the appliance manager to the UI at connection J4-4 to J4-2. I am getting 14 VDC. I am not sure why the appliance manager is sending 14 vdc to the UI but also sending the error code. I have tried clearing the error codes and discharging the relays on the appliance manager. No fix.

The display will change almost by the minute.
It can be programmed and used but after several hours it will lock up and has to be unplugged and rebooted then repeat the process.
One time the microwave came on on its own
Sometimes it will go into the service mode by itself. But the in a few minutes will go away.
At times it will go completely blank.
Can this be the harness in the door.
I need a tech sheet and service manual and service bulletins.
I see this is an issue with this model.

There is a lot of Frost BUILDING UP INSIDE THE REFRIGERATOR BEHIND THE PANEL BEHIND THE CRISPERS. What do you think could cause this?
