I have an LG LRFD25850ST whose water dispenser is no longer working. The ice maker works fine. I've replaced the water inlet valve in the door (connected to the water tank for the dispenser) and replaced the master water valve at the bottom rear of the unit - though the coils in the solenoids of the master valve all show the same resistance across the coils. After replacement, the problem persists. I've also tested the switch in the door connected to the dispenser and it appears to be fine (i.e. it closes the circuit when activated). It seems likely to be an electrical issue, but I can't tell from the diagrams what control board is involved. The board on this page (AP4439908 / 6871JB1281C) appears to have fewer, smaller gauge wires than the wires going to the solenoids in the control valves, so there appear to be other components involved. What should I be looking at next?

I have a LG ref. that kept having the temperature number on the temperature board display to constantly changing. I tried to replace the main controller board, but did not help. Do you think it would help to replace the temperature controller board w/part# LG6871JB1281C? Thank you for help in advance.

The user board display on the left door panel (where water is dispensed) flashes and resets every time I open the refrigerator door. It also beeps for about 10 seconds. A lot of stuff in the unit also is freezing. When I press and hold all five buttons on the display it seems to reset but then the whole thing happens again when I open the door. Because the display seems to be malfunctioning, I am inclined to replace the user board in the door. Based on the problem described above, do you agree this is the problem or is it more likely the control board in the refrigerator? Thanks, Bill
