LG Bottom Freezer Frost Issue

I have the same problem with an LG Model LFC25760SB. All of a sudden massive ice build up in the freezer unit. Four gallons of ice cream in the top rack just melted into soup. The unit is only 18 months old.

Any help or suggestions are appreciated.

It sounds like your defrost controller has gone bad. I have an LFC25760 and had ice build up in the bottom of the freezer such that water would start leaking onto the floor. The ice build up in the bottom of the freezer was due to a failing/bad defrost controller. Behind the back white wall in the freezer compartment exists the cooling fins along with a heating element underneath. Due to moisture that comes into the freezer from opening it, frost/ice builds up on the cooling fins. Thus the defrost controller turns on the heating element to melt the ice/frost off of the fins which then drips into a metal pan which channels the water to a drain hole which drops into the drip pan underneath the fridge next to the fan. The problem is that the defrost controller doesn't keep the heating element on long enough or the cooling cycle comes on too soon thereby freezing the water and plugging up the drain. I had my defrost controller replaced (just outside the warranty period!) and it worked for about 1-month and then same thing happened again. Instead of paying for another defrost controller that would probably not work 100% my serviceman used the old paper-clip trick. He took a paper clip, stretched it out and then wrapped one end around the heating element and placed the other end into the drain hole. Thus when the heating element comes on the paper clip keeps the drain hole warm/hot and prevents the water from freezing. It has been 9 months since this fix and I haven't had any ice pooling in bottom of the freezer.

This always happens when you don't have 'FROST-FREE' refrigerator. Unplug the power cord or switch off the freezer for about one hour or more when lots of frost stacks (maybe weekly). Turn down the cold lavel to 2-3 instead of higher if there are not so many items in the freezer.

Freezer has massive ice build up, refrigerator not cooling , no cold air thru chute


Possible that the auto defrost timer is not working and so the massive frost build up. This prevents the air to flow from vent to the fridge.
The auto frost must work on a determined setting of the timer cycle as the frost must clear so that the whole fridge is efficient.
So check the timerr which is normally placed in the rear bottom and is connected to the heater and is also inline with the thermostat.

The display will stay on normal for about 5 min and then give me a Er FF. What to do?


problem may be the main pcb or evaporator fan motor. this unit has several problems. if the model# starts with a 795 it was made by LG. the er ff code is caused most of the time from frost building up around fan motor. this can also be caused by freezer liner sagging at the top of freezer causing frost build up, sears has a service flash for this that is covered by the manufacture. service flash sf46-512. iwould call sears and find out if your model is on this service flash.

Doors won't stay closed!


Frost in the rear of freezer possibly caused by door staying open.  Door staying open possibly caused by frost buildup on ref door track.  Start by making sure the teeth on the freezer track are clear of ice and frost.  This should allow you to shut the freezer door.  Next check the freezer seal.  If it is not completely sealed it it will build up frost. It is also possible that the frost in the rear of the freezer is from a failure in the defrost cycle as the evap coils are at the back of the freezer. If this is the case your refrigerator is probably getting warmer.

The control is not seeing a feedback signal from the ice room fan. (the fan inside the freezer which pushes cold air up to the in door icemaker) It is probably blocked with a build up of ice or frost, preventing the fan blade from turning.
