check the damper door vent as it sounds as if it has frozen itself shut or possibly the cold control in the refrigerator has gone bad and can't control the door,the door is usually behind a diverter panel or a grille where the fan forces the cold air in from the freezer,the cold control is the component that you adjust to change refrige temp setting

Lower half of fridge side is freezing upper half is warm


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.
OR


The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can’t flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad it can prevent the heater from coming on OR it won’t turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it’s bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it’s in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others.

If you need help finding your model number see here> http://www.appliancepartspros.com/modelnumber_locator.aspx

To locate your timer, motherboard, control or adaptive defrost control , enter your model number and search for the part or post back on Fixya.

Freezer is cold but not fridge


there is a little trap door at rear upper corner of frig/freezer. (side by side type) Not sure where it is on others. Opens to cool refrig side closes when right temp is reached, Either link to operator is frozen or broke. Should be fixed (replaced) by repairman, easy, fast not too expensive.

Whirlpool gold:upper half of refridgerator side not cold


Either the evap fan has a problem, or the defrost system has failed. You should never see frost in the freezer section as the defrost sensor should sense that the coils need to be defrosted before that much frost accumulates.

Unplugging to clean out helped because the frost got a chance to melt away.

If you find the evap motor is running, then the things to check are the defrost sensor, the defrost timer, and the defrost heater.

Reply back if you would like more info.

Top half fridge not cold freezer department fine


I had the same problem; the top fridge compartment was warming up to 14C while the freezer compartment was starting to defrost (frozen stuff was starting to become soft. I took the rear wall off the freezer compartment and found it all iced up. I defrosted it with a blower heater then powered it back up. It all worked fine for a month when the same thing happened. I figured that the defrost cycle wasn't working. I located the defrost timer on the rear right-side of the fridge. I rotated it several times and found that the fridge was turning on and off. I rotated it until the fridge turned off. I waited 5 minutes then stuck my head into the freezer compartment and felt the rear wall at the bottom where he drain is; it felt warm so I guessed the defrost heater element was ok. I ordered a defrost timer and installed it. I haven't had a problem since.

Freezer not freezing


Check to see if the fan motor in the freezer is running. Most likely it is not circulating the cold air Also make sure the defrost drain line is clear and has drained out. A frozen sheet of ice will restrict airflow also
