Product review (5 stars): it looks fine. The freezer seems to be working alright
Our LG refrigerator  Model No: LRSPC2331T has recently developed a problem with the temperature setting display. The freezer side It changes temperatures on its own, erratically .  There is no pattern or particular time between these changes.  It will vary from low to high with no pattern.  It makes a chime sound every time it changes.  Sometimes it changes once every half second for three or four seconds, then changes to just once in awhile.but once it is locked, it looks fine. The freezer seems to be working alright, as there doesn't seem to be any problem with the food defrosting or ice melting.
I assumed the this PCB board is bad and the reason to purchased. After replaced this board, the refrigerator is operating normally.
If someone has this problem, no hesitate to buy this board. It will work for you.
