Frost build up


Hi

Poor cooling is often the result of a heavy frost build-up on the evaporator coils or a condenser that is clogged with dust, lint, and dirt. Determine the temperature setting. The refrigerator should be set to temperatures ranging from 34 degrees to 40 degrees, while the freezer should be below 30 degrees. Adjust the temperature setting which will naturally improve the ice buildup that's been caused by the wrong temperature setting.

Move the refrigerator away from the wall. Oftentimes, this simple action is all that is needed because the unit is not getting enough air circulation behind it. Also, some refrigerators have vents underneath the unit, which are easily clogged with debris. Clean these vents and coils.

Remove food and shelving from the refrigerator and freezer portions of the fridge. If ice build up is happening in the freezer, the drain in the freezer may be clogged. With the unit off, remove coverings to expose drain and pour hot water down the drain hole until it comes out into the drain drip pan under the fridge.

Check the condenser coils. The evaporator coils could be causing the problem of ice build up. If this is the case, professional repair is likely needed to replace the motor, thermostat or other problems within the fridge.

Hi,

If the refrigerator is not cold enough then please check the following and also click on the blue coloured links for more info.


How To Check the Temperature1x1.gif In most refrigerator freezers, the refrigerator gets its cold from the freezer. The evaporator fan circulates air over the coils in the freezer and cold air circulates into the refrigerator through vents. If the vents are blocked or closed, then the fridge will not get cold enough but the freezer will. If neither is cold enough, then the number of possibilities increases.
Lowering the freezer temperature will increase the cooling cycle activity. Setting the refrigerator temperature may have little affect on the cooling cycles because it simply changes the vent opening size. Decreasing the fridge temperature opens the vents more and increases air circulation from the freezer.
The temperature can be adjusted using the controls found inside the refrigerator or freezer. The ideal freezer temperature is about 0 to 5 degrees (F) and about 38 degrees (F) for the fridge.
Measure the temperature by placing a cup of water with a cooking thermometer into the refrigerator for about 2 hours or more. To test the freezer, substitute alcohol or cooking oil.


Goodluck,

Hi
You have condesation built up in your freezer whereby the evaporator fan or the vents are most likely blocked off.

Turn fridge off. Empty freezer and either put a pot of boiling water inside freezer or with the aid of a hair dryer try to defrost the freezer. If you are able to remove the back panel on the freezer that would be ideal as you can directly target the frost.
Good luck

Hi my name is veronica my problem of my kenmore elite refrigertor is not cold enought...i want to know what is the tempertaure that need to be on


Problems with Temperature
If the refrigerator or freezer is not cooling properly, check temperature settings and air vents and ensure there is adequate room for proper airflow. Factory-recommended temperature settings are 0 degrees Fahrenheit (-18 degrees Celsius) for the refrigerator; and 37 degrees Fahrenheit (3 degrees Celsius) for the freezer.
If you need to adjust the temperature, do it one degree at a time and wait 24 hours before making additional adjustments. Check the air vents and make sure nothing is blocking them. Finally, if your refrigerator or freezer is too full, there will not be adequate room for air to circulate and cool properly. If these all check out, the problem could be with one or more compressor components and will require professional repair.

Have a nice day : )

If you have a combined refrigerator/freezer thermometer, check the freezer compartment temperature too. You should have the overall temperature control set so that you have the freezer at 0 to -5 degrees F. All combined units will (or should, at least) have a control that allows you to divert a varying amount of the cooled air to the refrigerator.

GE refrigerator is cooling to 48 degrees F, but the setting is at 37 degrees F. The temperature on my furnace is set to 70 degrees F. Is this affecting the refrigerator?


The freezer may be overcrowded with food in this case cold air from freezer is not migrating to refrigerator compartment. Inside the refrigerator, at the bottom and on top, there are opening sliding door that allows cold air from freezer to circulate in the refrigerator. Make sure that they are not obstructed. Or simply, your refrigerator condenser is dirty and may need cleaning. If neither of this is the solution, get a repairman to check or fix it for you.

My frig. in the garage.. The freezer works great in summer months but in winter months it doesn't. Why is that?


Good day,
That is normal. The thermostat that runs the whole machine is located in the refrigerator compartment.
When it reaches normal temperature, it shuts off. In winter months that may mean as long as 12 hours or more. Thus not enough running time per day to keep the freezer near it's normal temperature.
Engineers design domestic refrigerators to be in an area comfortable to humans. Normally 70 degrees or higher. Thus your problem.
The only solution is to bring the machine inside.
Sorry.
