The freezer is cold, but bottom section is not cold

Its defrost problem.When the freezer section gets cold and reaches its required cooling temperature, after that the frost on freezer section starts defrosting and the cooling fan in the freezer section blows this cool air from freezer to fridge. But if the defrost cycle does not start then over ice will get collected on freezer ventilations and that will block the air passing section from freezer to fridge, so the freezer gets cool but fridge section does not cool.Try manual defrost by unplugging the refrigerator from main power outlet for 24 hours then reconnect it and check, if the same problem is noticed again,. If yes then its defrost board problem. The defrost board located in the back of fridge section. You can get required parts from www.repairclinic.com or from online sears part site. ------------- Thank you.

You have a frost blocked evaporator. Translation: The cooling coils, located behind the back wall inside the freezer section, have plugged up with frost (usually caused by a burnt out defrost heater, located at the bottom of these coils) which prevents the cold air from circulating inside the freezer, and into the top of the fresh foods section. At the same time, this blocked air flow allows very cold air at the bottom of the freezer section to migrate back into the bottom of the fresh foods section, and thus freeze item in the bottom bins of the refrigerator. Unload the freezer, take the shelves out and remove the back panel. Melt the frost with a hair blower, and change out the heater at the bottom.

It appears you need to get the cold distributed from the freezer section to the frig section. This can only be accomplished by a fan that forces the cold air throught openings between both sections. Since the freezer in at the bottom, cold air cannot go upward, thereforethe fan. Chech that the interior fan (in the freezer section) is running. Check that the air openings between the sections are not blocked. Finally, if all looks good, then maybe the compressor system is slowly failing and only making enough cold for the freezer, but not enough to be circulated. Goodluck, Macgivor

Most of these have a fan that blows the cold air for the freezer into the refrigiator section. If the fan quits running you will experience your problem.

The refrigerator gets its cold air from the freezer section through ducts and damper control. Check for blockage.

sounds like you have a defective temparture sensor

Replace the freezer fan motor.

Look to the freezer section for a possible frosting on the back wall. If you have a defrost problem in the freezer and air circulation stops cold air from the freezer may settle through the return area of the duct between the refrigerator and freezer section because cold air is heavier the warm air. Normal circulation follows a clockwise pattern.
Also your setting of the refrigerator temperature may be set to cold. Once again cold air settles to the bottom.

The defrost controller was changed and it resolved the problem. after a day power off to permit the ice to melt.
