Freezer icing up won't defrost. Refridgerator not

check doors for proper seal

This sounds like a classic case of defrost system failure, the coil in the freezer is iced up - freezer will run at 32 fridge around 55. turn off unit, get heat gun, manually defrost unit(be careful!). either your timer or defrost heater assembly has failed, if you de ice coil unit will work until you can get a service person to diagnose bad part and replace

Hi,
The freezer coils are iced up and that is blocking the sir flow to the fridge.... You have a defrost problem and that is causing the refrigerator to be warm...

Check out these tips...they can help you figure out what is going wrong withyour refrigerator and why it is not cooling

DEFROST PROBLEM
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(disconnect the two wires plugged into it and twist them together) 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. You can post your model number into one of several appliance parts sites on the internet and search for defrost components to find your parts.

you need a new thermostat and posible a defrost timer

disconnect the electrical portion of the ice make and check the controls for the refridgerator and turn it down a little , defrost complete unit and start fresh

Hi,

if the compressor is running your ref. should be getting cold. Their is a defrost timer but when it is in defrost the compressor shuts off. I think you do have a leak.

thanks,

you have defrost problem

Sounds like a defrost problem. Check to see if there is any frost buildup in the back wall of the freezer. If so, it is not defrosting as it should.

• possible causes:

1. bad defrost timer
2. bad defrost heater (in freezer)
3. bad thermo switch in freezer

If you don’t know what these are then unplug the machine and let the ice melt in the freezer overnight with the door open. Then try it the next day, if is cooling fine then you need to have a service person replace one of the above items.

• if you already checked this and think it is a different problem then let me know, i will help you figure it out.

hi, have you recently moved it? could be that gas is leaking.
