Samsung Refrigerator Ice Door Constantly Running - RH30H9500SR/AA

[jisenga8]

I'm facing a persistent problem with my Samsung RH30H9500SR/AA refrigerator, and I'm seeking some advice on how to address it. The issue is that the ice dispenser door is continuously running, and even after replacing the display panel, the problem remains unresolved.

Now, I'm trying to determine whether I should replace the auger motor responsible for controlling the door's open/close function or consider replacing the main control board (PD00035474). I've come across instances where people have opted to replace the entire door, but I'm unable to locate the part number required for replacing the door on my specific unit.

I'd greatly appreciate any insights or guidance you can provide to help me tackle this issue effectively. Thank you in advance for your assistance!

Looks like you still haven't received any help with this. Let me jump in and see if I can provide some clarity. When you say the door is continuously running, do you mean the flapper that dispenses the ice is opening and closing, or just remaining open?

The image below is the wiring diagram containing the "Ice Route Motor" circuit. Power comes in from Line, goes through the motor, and to the main board. Within the main board, it should connect the circuit to Neutral when it is supposed to. However, it seems that it is completing that connection when it shouldn't.

This is one of those scenarios where the wiring diagram can point us in the direction of how this component is receiving power. Without it, I would have thought the same thing - that it was routed through the dispenser assembly.

So, if that flapper is remaining open when it shouldn't either it is stuck open, or is opening and closing, it's either getting power when it shouldn't, or it's not handling the power properly. How I would approach is this: Unplug the fridge. See if the flapper closes. That is if the flapper is remaining open.

If the flapper is opening and closing in perpetuity, I would test for the voltage the board is sending it:

Neutral comes into the control board at CN70-1 (Black). You can take a meter and backprobe the Neutral pin, and backprobe the Ice Route Motor pin. If you've got 120 VAC, then it's completing the connection in the board, and sending voltage to the flapper when it shouldn't.

However, we also need to consider what is telling the control board to send voltage to the dispenser flapper.

For now, I'll leave it there. I would start by testing voltage at the board at the pins listed to see if the dispenser flapper is receiving a steady 120 VAC, or if it's going on and off, or what.
