Looking for this service manual for an LG fridge. I have found the manual for the 21760/25760, but they are just a bit different as far as the control panel is concerned.
I have an issue where the freezer is cold, but the fridge is warm. The evap fan doesn't seem to be working properly. It will kick on for a couple seconds when I first plug in the unit. I checked the heater for continuity-tested good. I replaced the defrost sensor today, no change. When pressing the test button on the control board, the evap fan will turn on normally. Not sure where to go from here I guess.
