Question about Refrigerators
ON ALMOST ALL REFRIGERATORS, THE FRESH FOOD SECTION GETS ITS COOLING FROM THE FREEZER BY AIR CIRCULATION. IF THE AIR ISN'T CIRCULATING, FINDING THE CAUSE WILL REMEDY THE PROBLEM. THE MOST FREQUENT FAILURE IS THE DEFROST CYCLE AND IS EASILY DIAGNOSED BY LOOKING IN THE FREEZER SECTION. IF FROST IS PRESENT ON THE BACK WALL, (OR FLOOR OF OLD MAGIC CHEF TOP MOUNT), THEN A DEFROST FAILURE HAS OCCURED. THERE ARE THREE COMPONENTS IN THE DEFROST CIRCUIT. THE CONTROL, THE HEATER, AND THE BI-METAL. FIND THE DEFROST CONTROL AND SET TO DEFROST. IF THE HEATER COMES ON, THE CONTROL IS BAD. IF THE HEATER DOES NOT COME ON, EITHER THE HEATER OR THE BI-METAL IS BAD.
TO FIND THE BI-METAL, FOLLOW ONE SIDE OF THE HEATER WIRE FROM THE HEATER TO A SMALL ROUND DISC WITH TWO WIRES COMING OUT OF IT. THAT IS THE BI-METAL.DETERMINE WHICH IS BAD WITH VOLTAGE OR RESISTANCE MEASUREMENTS.

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.Its defrost problem. 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.
