Question about LG LRFD22850 Bottom Freezer Refrigerator French Door
The LG fridges are all controlled by the board. Depending on the year of your unit, the unit will go into defrost once every 12 hours on the older boards, and once every 24 hours on the new ones. The older boards, were 12 hours, these were also the ones that had the problem. On the back of your unit, open the panel that covers the board, if it is 6871JB1375A it is old and could be the cause for the problem. You will need the xxxx1375D this is the modified board that should solve the issues.

Your problem of intermittent defrosting in the freezer may be related to a moisture problem in the refrigerating system. System have a refrigerant filter dryer installed which removed the moisture through chemically bonding it. In areas where high ambient temperatures are moisture will be released under hot conditions. A dirty condenser can cause moisture to be released when the system overheats. This moisture will circulate through the system and become as a block in the refrigerant feed. Once it reaches the freezer section it will become solid and hold at that point until it is again freed to circulate such as a normal defrost cycle.
This same condition can be caused if the compressor becomes overheated and cycles off on the thermal overload protector. This problem can be caused by a faulty condenser fan motor, dirty condenser coil, or a fault in the compressor itself.
