Ice build up on fan

Hello.
1.Check fan in the freezer if it runs fast.
2. Remove rear cover in the freezer after disconnecting power to the fridge and check if there is build up of ice on evaporator coil (looks as radiator).
3. If you find build up you have a defrost problem (timer. Defrost heater. Defrost thermostat

Check Temp inside freezer. It has to be down to about 10 or 15 degrees
This can cause slow ice making if its too high even tho its freezing everything else at 25 degrees
See if water is in icemaker.
Pour water in Ice Maker and wait to see if it ejects.
If it ejects thenyou need to replace water valve in rear bottom of fridge(Its the part that
attaches to water line out of wall)
If it doesn't eject then it is a faulty Ice Maker.
If its leaking same part needs replaced.The water valve at the bottom rear of fridge
First I would check the fan in the freezer. Listen to see if it is running
It moves air to the ref from the freezer
Then check to see if freezer control is turned WARMER, which makes the Ref. colder
Also this might be a common Defrost problem, Ice
is not being melted by the defrost system.The fan can't blow through the coils into the fridge.
Take out back panel of freezer to check for ice buildup. The coils should be clean.
There are three components to a defrost system- a heater,heater thermostat, and a timer unless you have a defrost electronic card.
Its best handled by a Technician but you could possibly do it by taking your model number to the nearest appliance parts store and asking for the parts. They are mostly located in freezer ,behind back panel on freezer coils.except the card which is usually located in ref The parts store will have info
Also check fan undernearh Ref in the rear
Clean condenser coils underneath

there is no way of cleaning the coils.there maybe a problem with the compressor.you should hear a fan running inside the freezer when it is in the cooling cycle and the compresor is running if you do not here the fan running this could cause a cooling issue and the evaporator could be building up with ice.
check the rear of the freezer to see if there is any ice build up.

the defrost circuit has a problem, allowing the frost/ice buildup..
remove the shelves, and back lower cover in the rear of the freezer to expose the evaporator coil, defrost heater, and defrost thermostat.
the defost heater should have continuity through it and the defrost thermostat will have continuity when frozen but test open when warmed.. if either bad replace.
if both test good look for bad connections in the freezer compartment wiring, and moly connectors otherwise the temperature controls are bad and it is an electronic assembly that incorporates the temperature controls with the deforst timer controls..
hope this helps,
best of luck,

Hi, Check the freezer and see if the fan motor is running. Remove the rear panel and check for a frost or ice build up inside the rear freezer panel. Please let me know what you find so I can assist you further.

Hi, look inside freezer and see if there is a frost build up on the rear wall. Also listen to see if the evapotator fan motor is running.
Please let me know so I can assist you further.

you may have defrost problem check see if you have frost build up in the freezer back wall

I had the same problem. I found the buzzing noise was caused by ice build up around the fan motor inside the freezer. I believe water must have leaked down around the fan during a defrost cycle. I removed the ice maker, the ice cube bin and ice dispenser auger motor. It sounds complicated, but it isn't too bad. The ice maker and auger are connected with quick connect plugs. So just unplug, remove the screws and remove them from the freezer. You will need to remove several other screws as well, I believe 11 in total as well as the top freezer rack. This will give you access to the white aluminum panel that runs from the top of the freezer to about halfway down the back of the freezer. After you remove the aluminum panel you will see the fan about half way down the freezer. I found a lot of ice around my fan. The fan blades were hitting the ice causing the buzz. Remove the ice and the buzzing is gone. It took me an hour to complete this repair. I hope this helps.

this should not be happening as a heater in the freezer should eliminate this problem.first check the hose is completely clear,if it is when your fridge goes into defrost mode you should be able to feel warmth near this drain or hear the ice crackling and defrosting thence draining via the rear tube also try removing the offending ice in the drain with hot water

Check to see if your drain tube is clear. Sometimes it freezes up at the base of the rear cover in these bottom freezers. Causing an ice dam.
