Jason for Model Number LFX31945ST I have a French door LG LFX31945ST. It seems to work fine for several weeks then will randomly heat up in the fridge to over 50 degrees. If I unplug the unit for about 5 minutes and then plug it back it then it seems to work fine again. I have my fridge set at 34 degrees but it seems so usually hover about 38 - 40 degrees based on my thermometer I have in there since this problem started so I can monitor the temperature. Last time it did this it seemed to be making a clicking sound coming from the control board area. Once I unplugged it and plugged it back in the compressor and everything kicked on and the fridge cooled back down to where it was supposed to be (or at least to the 38- 40 degree range). So what do I replace or check to figure out this problem.
Answer Jason, This issue would most likely be the relay on the main control board that controls the defrost intermittently sticking. It would be recommended to replace the main control board. Read More... Answered by AppliancePartsPros.com | Friday, September 23, 2016
