Uneven and reduced cooling frost forming on back wall of freezer

Posted by on

  • keniwe Nov 15, 2010

    The fridge side used to run fine on 3, now i turned it up to 9, and it's not really cold.

    The freezer side has quite a bit of frost on the back wall, and is only freezing the food in the center shelves, not at the top or bottom.

Either you've got a leaky door seal, or your defrost timer, heater or thermostat isn't working. If it's the door seal (easy to check with a business card, just insert it between the seal and the fridge, if it you can slide it in easily at any point around the door, the seal is loose), then just replace the seal or realign the door to seal properly.

Now the defrost heater. Every now and then, the timer tells the heater that it's time to get to work, while telling the cooling parts to take a break. The timer turns on a heater, usually located in the back panel of the freezer, which warms the panel, which melts the ice, and the melted water drains, through a hose, into the drain pan in the bottom of the fridge. When the cooling unit turns back on, the fan blows air over the pan and the water evaporates.

Everything is wonderful until one component of the "automatic defrost" quits working.
The heater and thermostat both require a continuity test. The motor can often be seen or heard to be moving (if you can hear it, it's ok.

Testing and replacement are not too difficult. (Hey, I've done it) A continuity tester is essential. A multimeter or voltage detector can be helpful. For replacement parts, either call your local appliance parts place, or google your model# and "parts", for example- " A4112030642 parts".

Keep us updated.

Oncce the fridge was shut off and left for a while the cooling had come back . If frost is seen it is a good indication as the compressor is working with sufficient gas within.
If after about 6 hours you observe cooling it is possible that the defrost timer is faulty.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge.
However if Ice forms then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off . If not the auto defrost timer, or the thermostat must be checked.
If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
replace the defrost timer, heater or thermostat one you have confirmed to eliminate one by one.

Turn your refrigerator off and remove the back wall inside your freezer section. Use a hair dryer to melt off all the frost and ice. The frost was blocking the flow of air over those cooling coils, resulting in very little cooling. The most likely cause of this condition is burnt out defrost heater(s). It can also be caused by a bad defrost thermostat, air leakage like a door left open a long time or bad gaskets, or a bad defrost control.

No cooling


Both refrigerator and freezer operate from one system. Air from freezer cools refrigerator. Check back wall of freezer for frost buildup. If frost is evident on the back wall of the freezer it indicates a defrost system problem.

Fridge cools at top and not propwerly at the bottom


Check the back wall of the freezer section for frost buildup. Refrigerator is cooled by air that comes from the freezer section. If the coil is frozen over the air is reduced going to the refrigerator.

Freezer is working fine,but fridge is not cold enough


Check the back wall of the freezer for frost build-up which would indicate a defrost system problem which would reduce or cut off air for cooling the refrigerator section. Service may be required.

Defrost system problem will be indicated by frost (snow) on back wall or cooling coil is located in the freezer compartment. Check freezer control setting. If it is set to cold for the freezer it reduces cold air to the refrigerator section.
