Problems with Whirlpool 21.0 cu. ft.

Not a 5 min. explanation, but in short, if the compressor and fan are both running, question is, Is the freezer cold but not the fridge? If so, defrost properly for approx. 12 hours to remove all ice then restart. If not, one of 2 options remain, there is either a Blockage in the system, or there is a leak in the system. Either way, you need to call a service technician. Truthfully, if diagnosed with a leak, i suggest you replace the fridge as these leaks do not get repaired properly especially if it is internal and good money will get wasted. Hope i helped.

check the fan in the freezer part behind the back wall in the freezer there is a fan see if it is run... if not it might go bad :(

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.

SOUNDS LIKE THE FAN FROM THE FREEZER TO THE FRIDGE TAKE OFF THE COVER TO SEE IF ITS WORKING

Sounds like the compressor is frozen and won;t turn. a slight chance that it starter relay is bad, you will need to get a repairman to check it out.

I do not understand your question because your note says it is a top freezer, but the fridge is ok?
The bottom section IS the fridge on this type.

The clicking is from your compressor relay on the side of the compressor it has eather went bad or a condenser fan motor is not running this will cause the walls to be warm if the fan is running in the back try cleaning the coils hope this helps

3 things to check. If you didn't adjust the damer from the freezer to the refrigerator, like closed it off. Is the freezer fan running? The fan blows air from the freezer to the refrigerator section. Some fans shut off when the door is open so you may have to push in the door switch to check this out.
Look for ice on the back wall, of the freezer section, If present then the defrost cycle is not working. The evap. coil is icing up and there is no air blowing into the refrigerator. Set the thermostat back to the normal setting it just causes a longer run time on the freezer section.

Your fan in the freezer is wearing out. When your food in the freezer is blocking the air, the motor is working too hard. After years of using, it needs to be replaced. Get a repair man in to replace with a new parts. My Fridge/Freezer was totally broken and I found this out because the ice was melting. It got fixed and now no problem.

Check the defrost timer, rotate it until a solid click is heard. If your unit starts to work replace that timer. Good Luck
