My refridgerator is having problems the freezer works but the bottom part doesnt work need help

You most likely have a failure in the defrost circuit. One or more of thee possibilities: Heating element, defrost timer and/or defrost thermostat.

I had this problem. The Evaporator fan in the freezer was working but no air would be circulated from the freezer into the refridgerator. To test this you open the door of the freezer, and depress the door button(s) of the upper refridgerator doors so that the light extinqueshes in the refridgerator. This will engage the evaporator fan in the freezer. You can check to see if air is venting from the freezer into the refridgerator by feeling the holes at the top most part of the multi-air flow channel in the refridgerator. If air is comming out when the freezer door is open, close the freezer door and feel if air has stopped. If you have kept the upper door buttons pushed in on the refridgerator and now have the freezer door closed, you should still hear the fan running, but may have not air flow with the freezer door closed. The cause of this is the air return channel from the refridgerator to the freezer is either frozen or clogged. My return-air channel was not frozen but clogged by a residue from something that spilled inside of the bottom of the refridgerator. The return-air channel has two vents in the rear-bottom of the refridgerator that exit into the freezer behind the evaporator (cooling coils). You can't see it even if the back interior panel is removed from the freezer compartment.

The bottom line here is that if air is prevented from moving from the refridgerator, back down to the freezer, then your refridgerator will not cool, but your freezer will work just fine. You will not need to replace the fan, unless the fan is not functioning. You may need to check the dampener, to ensure that your multi-air flow channel is open - (allowing air to come into the refridgerator). The multi-air flow channel is easy to remove once all of the shelves are removed from your refridgerator. Only 2 screws holding it in (securing the center rack top and bottom). The top screw is located behind a small plastic cover that can be removed.

That's what worked for me.

Check all coils for dirt and hair build up.
They can be cleaned with a soft brush and a vacuum.
Some are on the back of the fridge and some are on the bottom. Without proper air flow the heat cannot disapate very well. Check the vent holes inside the refridgerator side to see if something is in the way.
The freezer sends the cold air to the refridgerator through these vent holes.

WHAT IS HAPPENING IS THECONDENSATION IS FREEZING INTHDRAIN PAN IN THE FREEZER.WHAT YOU NEED TO DO IS TAKE THE BACK PANEL OFF IN THE FREEZER COMPARTMENT.ALSO THE BOTTOM TRAY IN THE FREEZER.YOU'LL NEED TO MELT THE ICE WITH HOT WATER THIS WILL WORK FOR A WHILE.MAKE SURE YOU DEFROST THE DRAIN TUBE AS WELL,LITTLE MESSY BUT IT WILL WORK.HOPE THIS HELPS.

change the thermostat as well as a technician if i see the heater is ok i change the thermostat and defrost timer together the thermostat  is iffy(if thats even a word) it works sometimes sometimes doesnt unless they obviously bursted but if they are in normal shape doesnt mean they work properly because of the fact that they work sometimes sometimes dont
feel free to ask any questions

Most of these have a fan that blows the cold air for the freezer into the refrigiator section. If the fan quits running you will experience your problem.

is it side by side or freezer on top/bottom...check to see if the fan inside the freezer is running when the compressor is running..also check to see if ice is covering the evaporator coils.. the freezing should be even with a thin layer of ice/ not partically melted..sometimes the ice forms in the vents and stops the air flow...to review...check and see if fan is working in freezer
check to see if vents are clogged......good luck!!

Does freezer back wall have ice build up ? if so a defective heater is the most likely problem

Check for frost build up behind back panel. Defrost system consist of defrost timer or adaptive control board, defrost heater, defrost thermostat. check them here
