FRIG AND FREEZER WON'T GET COLD AND FAN STAYS RUNNING WHEN DOORS ARE CLOSED

the damper vent door between the freezer and fridge compartments is frozen shut or if motor operated it broken or the motor is bad or power to motor is missing to open and close this door to let cold air into fridge from freezer also there is an evaporator fan near here make sure it is operating or cold air wont be moved

Hello,
That can be the result of a couple things. Check to see if you hear the fan running in the freezer side? If not, since cold air falls, the cold air could be migrating from the freezer into the frig bottom section through the air duct hole in the back of the frig behind the crisper drawers. If the fan is running the check the air damper in the top left of the frig section. If the frig side is cold enough you should not feel air blowing through. Air flow is only very slight. You will have to remove some plastic cover or duct piece to see if it is closing. If the air damper seems to be working properly, you may have a refrigeration problem indicated by frost build up on the lower part of the freezer back wall. You may want to call in a pro at that point. Hope this helps point you in the right direction. Good Luck

Put your unit on a 24 hr defrost the freezer coil is frozen and blocked with ice the fan cannot draw any chill from the freezer section.

The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.
The problem could be the electronic control if you have one or the mechanical linkages.

check to see if the fan motor in the freezer is running. all the cooling happens in the freezer and the fan is what circulates the cold air down to the refrigerator.. if the fan isnt running ,it could be a bad connection or a bad fan motor..on some models the doors need to be closed before the fan comes on so just push on the door switch to check .if the fan is running then a defrost problem may be the problem.. you mentioned you defrosted the unit. if the auto defrost isnt working, you would notice frost on the back of the freezer. there would be a lot more frost behind that panel that could block the airflow down to the frig. you would have to remove rear panel of freezer to clear all the frost and restore proper airflow..remember to unplug the frig before doing any work..

Look for a blocked duct or a bad fan motor in the freezer. The cooling is done in the freezer and the cold air is circulated via ducts and a fan. No air flow= No cooling in frig. Long shot could be a light not going off when door is closed, seen that a few times in 20 years...

sounds like fan motor between freezer and frig is bad,, you shoud hear it run when you open and close the door if this helps you in anyway be sure to rate me
thanks sawdust46

Is this a self defrost model? Frost inside the freezer could be an air leak around the door gasket. Remove the back panel in the freezer and completely defrost the coils. Is the fan running in the freezer. That will make the frig not be cool. With the door closed peek in the gasket to make sure the light is shutting off, this will warm a frig also.

Often times the defrost termination switch (which opens when it gets warm enough) will hold the fan off until it closes again when the freezer runs. It is possible that the switch is not closing, but be sure the freezer is getting cold enough for it to close.

You know the freezer is likely cold enough when you see frost covering the entire evaporator coil after a few hours of operation. A partial frost pattern could indicate low refrigerant, or a restriction of refrigerant.

I couldnt find a diagram of this frig.

Some of the evap. fans run thu the defrost thermost ..u could try by-passing thermost and see if fan comes on...  have you checked with volt meter if there was power at the fan motor?
