My friend reported to me that her freezer is working fine but the refrigerator is not cooling. I want to take a look at it before I make a service call.
Outside of a faulty fan is there anything I should narrow in on considering it has cooling capabilities? thank you!
Is this a good question?

Most Frequent Causes for Refrigerator freezer is cold but refrigerator is warm
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.

Thank you for your speedy reply Mayer. I will be checking this out this evening and will be sure to let you know how things went.
I had the same problem with an Amana top fridge bottom freezer that the fridge was getting warm, but the freezer was cold. I read up and unplugged and let the ice melt off from the coils and tore it apart and cleaned and vacuumed and oiled fan, even though the bearings seem to be great. I put in a new defrost timer and re-assembled, and plugged it in and the next morning it was cold as heck on the number 4 setting. I have checked it out in our garage several times over the last 4 weeks and it was great. I was getting ready to sell it and I went out to check it today and the whole fridge and freezer is warm. What the heck? Please help!
