The cooler has ice build up on the in side around the fan everyday or two .i have to to unplug it let it defrost then fine great. this just started how do i fix this problem.
The system is most likley working fine.
The problem is moisture in side the unit. It needs to be dry inside or ice will build up on the cooling unit. make sure the lid is fully closed also.
It's possible that the inside fan isnt working or is spinning too slow. You'll need to take the plastic cover off to see for sure. If the fan isnt working the inside fins will freeze up much more easily because warm air isnt blowing across them

It could be many things. My first guess would be the defrost. The coil that gets cold in your freezer builds ice on it and the only way to get the ice off is to run a heater near the coil long enough for the ice to melt. All freezers have something built in to defrost and domestic are typically just an electric heater on a timer. When your freezer stops working again, you may want to pull open the panel of your freezer and see if your coil (a heat exchanger that probably looks a lot like your car radiator) is covered in ice. If it is, it could be the timer or the actual heater that is bad.
A COUPLE THINGS U SAY FREEZER IS FINE FRIDGE IS NOT? THE FAN NOISE MAY BE DUE TO ICE BUILD UP DUE TO A DEFECTIVE BAD DEFROST TERMINATOR. WHICH EVENTUALLY WILL BUILD ICE UP IN FREEZER AND FRIDGE? HINDER COLD AIR CIRCULATION. ANOTHER THING TO LOOK AT IS UR FREEZER AND FRIDGE THERMISTORS AND UR COLD CONTROL THERMOSTAT. EVEN UR AIR FLOW DAMPER CONTROL VENT AND KNOB SETTINGS? ARE THEY TO FAR OPEN OR CLOSED? ARE U ABLE TO HEAR THE FAN AND COMPRESSOR RUNNING? ANY CLICKING SOUNDS?
Check the control knobs, make sure they are not turned all the way on high. If not and you have ice building up on the panel below the one with the fan, you will need to go back inside where you replaced the fan and replace your defrost heaters also. It will be bast to replace the defrost thermostat while your in there. It only cost around $15.00 and will save you trouble later. You could see both of these parts behind the panel the fan is in. The heater in you model is a cal rod type, made of the same material that ele stove elements are made of. You can ohm it and if it has no resistance, it's bad. If it does then the defrost thermostat is the one bad.

Could be the fan needs to be lubed. Pull the covers off, take the fans off, pull the stickers off the fan and put some light grease in the small hole. Put back together and try it.
BE CAREFUL WITH THE FANS, you can break the blades very easy
If there is frost on the back wall of the freezer, then the compressor is running. Another (maybe) good thing is the fan is running.
The problem could be -
1) Bad defrost heater 2) Failed defrost sensor 3) Failed defrost timer or refrigerator controller board.
There are diagnostic tests to determine the problem, but require skill at using a multimeter and possibly reading a schematic/wiring diagram.
You can temporarily make the refrigerator run again for awhile by unplugging, opening the doors, and defrosting for 6-8 hours (store food in coolers.). Then plug it back in. Note, water may come out of the freezer as a result of defrosted ice.
The fan should blow air into the heat sink. The warm air exits the
heat sink at both ends. (It might work the other way, haven't tried
it.)
When you have ice in your cooler, you know the thermo-electric element is working well--it's below freezing!
Ice builds up because there is water in the cooler. For example, in
humid weather, you open the cooler, some humid air gets in, and the
cooler temperature condenses the water. You have to empty this water,
either by tipping the cooler, or using a sponge.
You can easily defrost the cooler by unplugging it for an hour or so.
You know it's time to defrost when you hear the fan blades making a
racket because they're hitting something--a thick buildup of ice.
the ice maker wont cycle untill the temp of the ice is around 10 degrees so if the freezer is at 15 or 20 due to some other malfunction then you will see the maker full of ice but it wont harvest and make another batch. so you could have a sensor bad, control malfunction, refrigeration issue, compressor, defrost system malfunction(you mentioned ice build up)
inside the fridge there is a cold radiator which has filled with condensation or water from freezing it when say cleaned out the fridge this can be remedied by letting set for a few days outside in the sun so that water can evaporate properly or you can call a repair man and he can pull out frost radiator inside and defrost all the water out by dry wet vac and heater dryer
ice builds apon ice even a little bit can build up to a mountain same thing happended to my top end whirlpool i pulled the metal grate and defrosted this by pouring tap water over the ice which it went down the defrost tube outside water drain this helped greatly havent had trouble with ice since
chances are you have a defrost problem check the back of the freezer for ice build up if so here is your problem defrost system if not push in freezer door switch and see if you hear a fan running do this any ways if fan dont run the coils will freeze up also to defrost the easy way unplug unit until ice melts this wont cure the problem but will let it run 2-3 more day until you fix it
is it frozen up? do you have any air flow thru the air tunnel from the freeze to the fridge? Check your air flow with the door switch pushed in. also check to see if the damper door opens...
1) if it is iced up you have a defrost problem. most likely a defrost timer. Turn off or unplug untill all the ice has melted off the evaporator back of the freezer..plug back in and it will work fine untill the ice builds up again. if this work you do have a defrost problem.. if not let me know and we can go deeper...
