You either have a blockage inbetween the freezer and fridge or your condensor coils are filthy.

Help my frig is dying! The freezer compartment is working fine-but the frig compatment is nit colloing at all! What is wrong?

If the freezer is working that is a good sign. Here are what might be the problems; 1) Ice build up in the freezer will block air flow to the refrigerator and thus causing it to get warm and stay warm. If you observed a build up of ice in the freezer, it means that your defrost heater and/or your defrost thermostat is bad. In any case, replace both.
2) The evaporator fan plays an important role in circulating cold air in both freezer and refrigerator compartment. Listen for the evaporator fan and make sure that is running. If you can hear it, it has gone bad and will have to be replaced.
3) if any of the above applies, the lower or upper air dampers may be obstructed. Check and make sure that they are open.
4) Too much food or stuff in the freezer may also be the culprit. If there is too much stuff in the freezer, you might want to remove some them to make way for air to flow in the refrigerator compartment.
I hope this will help solve the problem. Do not forget "Feedback"

You may have the temp. set TOO HIGH for the freezer, set it in #2, leave the fridge setting in the mid range for now. Check after 24hrs. and adjust as necessary.

Good Luck!!

This is a common question here.... The most common solutions are that either the fan has stopped working or the defrost is not working and the ice build up stops the fan.
First unplug the refrigerator for 12 hours or so to see if there is ice build up that is stopping the fan. If the fan works when you plug it back in then find out why the ice is building up. Ususally it is because the defrost timer has gone bad.
If the fan still does not work then most likely the fan has gone bad. You will need to replace the fan.
The fan blows a portion of the cold air from the freezer side. If the air is not forced oover to the refrigerator side. the freezer is great but the refrigerator is warm.
Hope this helps you understand what is happening and ultimately solves your problem for you!!

I have a Kenmore side by side refrig (no ice maker) Freezer works fine. The refrigerator side is not cooling. I have cleaned out the vent between the freezer and the refrigerator section by defrosting the...

Check to make sure the evap fan is running.
IF so, then let unit defrost, then turn back on, check for air comming thru top of refrig vent, if air moving ok, then let run for a few days and see if refrig warms again, if so then check for frost build up on back wall of inside freezer, if so, you have a defrost problem. With a defrost problem, defrost heater may be bad, defrost timer/electronic control may be defective. Either way, in most cases it is a defrost problem unless you don't have air moving and fan is running in this case you have a damper door problem inside air duct in refrig.

Kenmore refrig not making ice and top shelf area in refrig not cold

if you are having tempurature issues make sure the fan in the freezer is operating. it should be on when the compresor is running. this may explain both warm fridge and no ice.

Hot Point Side by Side. Freezer works, Fridge not cool enough

check freezer for frost build up and if fan blowing, check condenser make sure clean, and fan blowing, check vents in refrig. make sure no blockage, freezer control should be in the middle setting, you can try turning that to Warmer Freezer allowing MORE air to refrigertor side.

Amana French Door Refrigerator "on" but no cooling; freezer still works

There are 2 possible problems. One is the defrost cycle is not working properly this is usually indicated by a large amount of frost on the back freezer panel. If so, the circuit will have to be repaired and the evaperator thawed to remove the ice build up. The other is the fresh food damper is not working properly this is behind the "lump" in the back of the fridge compartment above the top shelf, remove the louver panel to see if it is open or closed. closed will be warm open should be cold. The water dispenser reservoir is probably frozen due to poor air circulation.
