I have an LG French door fridge that has stopped dispensing water, or making ice. I have checked the inlet valve at the back and it works fine. Where do I go next? I assume there are other solenoids that control it the ice maker gets water or the door dispenses water. And I’m sure there are associated switches and control boards for those solenoids. Any videos and parts diagrams for this? My model number is Lfx33975st.
