Fridge freezing everything

If your freezer is icing up it is the defrost mechanism consisting of the timer, heating element, and defrost thermostat.

When you unplug unit everything melts and it runs fine for a few days till it freezes up again.

Usually it is the heating element that just burns out and has to be replaced.

you should send model number,if you have a damper control in your model most likely this is the problem,all that happens is cold air blows over from the freezer from the evaporator fan and blows through the top section of the fridge side,if the damper door isn't closing all the way it will cause freezing in the fridge section.

Make sure you clean the backside of refrigerator at bottom from dust. Make sure you have the recommended clearance from wall. Also make sure the food in freezer and frige have clearance to allow air to circulate around food. Keep playing with your controlls...The dails might be on wrong

Make sure that the fin tubes on the back are not loaded with dust, clean off and don't over load the freezer section. If there is no room for air flow the temperature will keep getting colder to compensate for low air circulation, thus freezing items in the lower section.

Can anyone tell me what year N500B was made?

To repair this problem I dont think just toggling a lever is going to work. You need to locate what is suppose to sense the temp in the fridge section and how it stops the air flow to the fridge section. Basically most refrigerators cool in the freezer using the freon coils and transfer the cold to the fridge section using the fan in the freezer. Then your thermostat (temp sensor) stops the air flow by either turning off the fan or closing a small door going to the fridge section. This door is called the baffle and if you put your hand up to it and can still feel air coming thru when the temperature is 39 degrees or lower its not doing its job. With a model number I could help better but my guess is if its not freezing everything only the veggies your thermostat is off or the baffle is unable to close all the way and may have ice or debris in it. Either way I hope this helps.

maybe fridge fan not working when door is closed could also be iced up air ducts between fridge and freezer

I need your model number, you may have a problem with your thermistat. Sears uses a different model number system than everyone. The model number will look like this 231.0564879 for example. Or yours may have electronic vents. Let me know, Thanks, Sea Breeze
You may need to contact me because Fixya has a problem letting me know if you respond.

You might have a defrost timer issue
