Hello Everyone,
I have been trying to troubleshoot this LG LMXS28626S fridge all day with no luck.
Problem: The screen is blinking and it is making a very loud noise coming from the water dispenser area. This is nonstop (see video below)
Background: The fridge is 15 months old. We have never used the ice/water dispenser system. It is disconnected.
Attempted solution: I took off the entire ice dispenser system from the circuit and pulled the plug. Instead of making the noise constantly, it now makes the noise around every hour.

Any idea what the problem is and any other solutions?
Thank you so so much in advance

Hi, Sounds like the Main PCB is possibly faulty.

Here's the Main PCB for your model:
EBR83845003 Pcb Assembly,main


Let's see if others can confirm that too.

Hi everyone,
So I got this EBR83845003 Pcb Assembly,main online as instructed.

But when I opened the fridge in the back, I saw this EBR86093796:

Is this compatible? Please check out the connections.

Thank you in advance for your help.
