Cause 1
The Evaporator Coils are Frosted Over
The defrost heater assembly turns on a few times throughout the day to melt away any frost that may have accumulated on the evaporator coils. If the defrost heater assembly is defective, frost will continue to accumulate on the evaporator coils, and the coils will become plugged with frost. If the evaporator coils are frosted over, the airflow through the coils will be restricted, causing the refrigerator not to cool. Check the evaporator coils to determine if they are frosted over. If the evaporator coils are frosted over, test each component of the defrost system.
Cause 2
Evaporator Fan Motor
The evaporator fan motor draws cold air over the evaporator coils and circulates it throughout the freezer. If the evaporator fan is not working, the freezer or refrigerator will not cool adequately. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, replace the fan motor. Additionally, if the motor is unusually noisy, replace it. Finally, if the motor does not run at all, use a multimeter to test the motor windings for continuity. If the windings do not have continuity, replace the evaporator fan motor..
Cause 3
Damper Control Assembly
The air damper control opens and closes to let the proper amount of cold air into the refrigerator compartment. If the damper does not open properly, it won’t let enough cold air into the refrigerator. Check the damper control to determine if it is broken or stuck closed.

I dont know bow this happened but the cold /colder dial is reversed ,the vent is opened wider from the freezer to the fridge when the dial is on cold , why ?
check the bottom return vent [vent letting air out] on the fridge side . It could be full of ice. see return vent on this webpage.

Open the very back where the coils are I just did it cause I tried telling my landlord he didn’t answer so I did it myself instead. Mine were all frozen all I did was grab some hot water and scrape off all the ice I could works 100% now. Easier then Having all my food go bad. I literally just got done doing it and had to post somewhere cause I get frustrated when everyone posts they have a problem but no one answers it lol

Hi @estebangar11897,
If there an ice build up on the evaporator coils to that extent this means that there's a defrost problem, if it's an auto defrost refrigerator.
This could be due to a faulty defrost heater, faulty defrost thermostat, blocked drain from below the evap unit to the evap pan under the refrigerator or depending on the model a faulty defrost timer.
If it happens again and it most probably will you will have to get it checked out otherwise you will have to manually defrost it every time.
What is the make and model number of the refrigerator?

Anyone looking for answers to this I just solved this. I opened the back of freezer and everything was frozen I scraped all the ice off with warm water and then works fine. You have to open the very back where the fan is and the coils are inside the freezer.
