Frezzer & refrigerator not cooling. Ice build up on top right side of evaporator

Hi. The fridge sensor is part # DA47-00095E. It is located behind the rear cover inside the fridge on the evaporator area and will need replacing.

Here is a link to the part you need.

Your cooling comes from the freezer side through cooling tubes to the refrigerator side.

The first thing is to make sure that the evaporator fan is working, because that will blow the cold air into the refrigerator side. If it is working then you probably have an ice build up around the evaporator. You will need to remove the inner rear panel of the freezer to check it.

If there is a lot of ice on the evaporator fins then your defrost circuit is not working. But if you manually defrost the freezer (a hair dryer will speed it up) and make sure the cooling tubes are clean of ice (can feel the air from the hair dryer on refrigerator side) then you will have anywhere from a few days to a few weeks before the ice build up returns.

So you should troubleshoot your defrost circuit and get the parts on order to be ready for the next time.

You may have a circulation problem. Check the the vent, if it's a side by side, inside refrigerator, on top towards back and feel for airflow. If there is no airflow from freezer into the refrigerator then you may have a evaporator fan that went bad or else you have a defrost problem - evaporator is clogged with frost which inhibits air flow.

the defrost heater is bad on the evaporator coil in the freezer section,you need to remove the evaporator housing cover in the freezer compartment,it will be a plug in unit located at the bottom of the evaporator remove it,then plug in new heater assembly

many times when a unit has a defrost problem the coils freeze up and do not allow the fresh food side to cool properly...check for a build up of ice on the inside back wall of the freezer compartment. if there is a build up of ice, you have a defrost problem. Also, check to make sure the evaporator fan in the freezer is blowing the air into the fresh food side.

1. check rear wall of freezer for ice build up, if so unit is not defrosting
2. check to see if fan is running in freezer
3. check to see if compressor is running

Is ice building on the rear wall of the freezer? Is the evaporator fan operating when you press the light/door switch on freezer side with door open?

a defrost problem, is gonna cause excessive ice build up in hte frezzer lower compartment. for somereaon the hdefrost heater was not energized. most common reason is a bad defrost thermostat, clipped on one of hte evaporator coils has gone bad,

Ice build up on back wall could be defrost thermostat or faulty defrost heater
