Niether side getting cold there is ice on the back wall of the freezer side

Do you see any ice buildup on the back wall of the freezer or behind it?
Is the compressor running?

Replace the defrost thermostat located on the coils in the freezer. Here is the part to order.

most likely you have a bad computer board if the freezer is getting warm too.if there's no ice on the back wall of the inside freezer wall then it's the board.you can check this site out

next time send the model number,where is the freezer is it on top or bottom or side by side,anyway all the fridge does is get cold in the freezer and the evaporator fan blows cold air from the freezer into the fridge section and then it returns to the freezer just goes around until it gets cold enough and then the t-stat tells it to shut down so if the freezer is cold you either have a bad fan motor,open the freezer you should hear the fan blowng around in there if not the evap fan motor is bad,also touch the back inside wall of the freezer if there's any frost or ice on the back inside wall you have a defrost problem,bad timer or board,bad defrost thermostat or a bad defrost heater,the ice doesn't melt off of evap coil because one of the parts have failed,the air ducts get blocked with ice and the cold air can't blow into the fridge section,or if you see ice on the ceiling,side and back walls the door was left open and the air ducts blocked with ice,or one more thing if the freezer is on top and you have water dripping into the fridge section the drain in the freezer is blocked and the defrost water can't go down the drain hose,the water is freezing the air ducts up,the drain has to be cleared and all the ice has to be melted out,and yes there is one more thing it could be, some fridges have a damper in them,all it is is a door that opens and closes to let the cold air from the freezer blow into the fridge section so this is why you have to send the model number.but your problem is the cold air in the freezer isn't getting blown into the fridge section because the fan isn't working or the air ducts are blocked with ice.

this could be a defrost problem do you have ice build up on the rear of the freezer wall?

if you can hear the fan still blowing but no cold air coming up to fridge section a common problem with bottom mount freezers is the door gets left open and the air ducts freeze up and the air can't blow up to the top.turn the control off in the freezer.remove the top shelf and the door,check to see if there are any screws one on each side of the slide arms,if there are remove them and lift the door up and out,with a hair dryer melt out the ice by blowing the hot air up each side of the back wall,also if the back inside wall of the freezer is covered with ice or like snow then you have a defrost problem but if there's no ice on back wall do what i said and blow the air up the sides of the back wall through the vents until no more water is seen dripping through the vent holes,then turn the freezer back on and check to see if you feel cold air blowing in through the vents in the fridge section,if you feel cold air then you're all set,if not keep blowing the hot air up the sides until it's melted out.let me know what you find,you'll know if the door was left open,ice will be on the ceiling near the light switch and sometimes on the top of the freezer door

The bdefrost heater behind the wall inside the freezer is bad if the ice you have is on the back wall of the freezer. Remove the back wall and deice the coils and replace heater. wr51x10101

If it has ice buildup on the back wall inside the freezer, it appears to have a defrost problem. Unplug it, put your food in another unit (or ice chests), open the freezer door and let it thaw out overnight for at least 12 hours or more, or until all the ice has melted from *behind* the back wall. Then close the doors and run it for 4 hours and check to see if the fresh food side is cold. If it is, call a repairman to fix the defrost problem. That could be a burned out heater, terminator, or defrost timer depending on your exact model.

usualy a defrost problem check for ice on back wall in freezer thats most common problem check for ice on wall in freezer ice build up is due to defrost system failure

yes.you will have to replace the ice maker.if further used without replaceing the compressor will get damaged and you will completely loose cooling in your unit.
