During a defrost cycle, the compressor and evaporator fan are both turned off and the temperature in the freezer compartment (and by extension of the evap fan being turned off, the refrigerator compartment) is allowed to rise to start melting the accumulated ice build from the evaporator unit, which drains to an evaporator pan under the cabinet to be naturally evaporated. This defrosting action is sped up by turning on a defrost heater under the evap unit.

Update:
-
It is a timed event as you don't want the frozen food in the freezer to even begin to start to thaw. There's also a defrost sensor, that monitors the temperature close to the evap unit to ensure that it doesn't get too hot as it is only made of thin aluminium and is designed to work at below freezing temps. If the temp near the evap unit (remember it is above the defrost heater and is not the actual temp in the freezer) gets to 46°F the heater is turned off and the defrost cycle is ended early. This can occur if there's little ice buildup on the evap unit so it doesn't take long to melt.

Wasn't looking at charts correctly. Apologies.
-
At the end of the defrost cycle both the compressor and the evap fan are turned on again to drive the temps back down to their respective set temperature. The refrigerator should then cycle between the upper and lower preset range of their temps i.e. compressor/evap fan on and off as required until the next defrost cycle occurs.

Try running the refrigerator in [link|https://www.manualslib.com/manual/1136405/Lg-Lfc21770st.html?page=27#manual|test mode|new_window=true] and check if any error code is being displayed indicating a sensor problem etc.

Best that I can find out is that your model performs a defrost cycle once every 4 hours of cumulative compressor run time. What this means is the actual total amount of time that the compressor has been running and ''not'' the amount of elapsed hours e.g. from 6:00p.m. to 10:00 p.m. It may take a lot longer than 4 straight hours to accumulate 4 hours of actual running time as this would depend on factors such as time of day and activity using the refrigerator e.g. during the middle of the night the compressor might not run for hours at a time as the ambient temp is cooler and the doors haven't been opened as often if at all, thereby losing cold air as is more likely during the day etc.

If the temps in both compartments are within 2°F of the expected temp then most probably it is OK. You can check if it is OK by checking if the food in the freezer is staying frozen during a defrost cycle, by placing a glass of water in the freezer and then once it is frozen solid, place a coin or similar object on the top of the ice in the glass and then check it say 24 hours later to see if it is still there or if has sunk at all. Don't be surprised if there's a layer of frost on it though due to the freezer door being opened/closed due to normal activity and warmer air settling on the coin and then condensing and freezing. It needs to have sunk lower ;-)

The codes are on the previous page to the one linked.
