Ice Build up behind refrigerator internal panel
I performed the repair to my own refrigerator, after watching multiple YouTube videos. I installed a secondary heater for the defrost coils and replaced the defrost sensor. The defrost sensor was actually bad. Today, 1/27/2024 I rechecked the fix from last week. All seems to be good so far.
If I get any build up of any ice on the bottom tray of the recessed panel where the drain port is located. I suspect I will also need a new Defrost Heater as well. For now the refrigerator is operating as expected. There is a small amount of ice build up as of today.
Also, I had recently replaced the drain tubes, added a longer heater element part to fit the drain hole, and cleaned the fins in the back of the refrigerator. Thank you.

Fridge side no longer cooled, freezer still workekd fine.
A couple of blogs said the freezer defrost sensor should be replaced, so I ordered one. Did not fix it. I did, however find a service manual online and one of the blog sites and it showed me how to remove the inside duct work. I discovered the fan the recirculates the air across the evaporator coil was not working. Ordered a new fan motor and installed it, fridge works perfectly now.

Refrigeration side was not cold enough.
Replaced the Broken Cover Motor and the Fan Blade. Fan motor was test with 12VDC power supply, or by replugging fan connector and holding down the door closing switch.
After a few days, the fan made loud noise. Due to defrog heater was open when it was test with ohmmeter. Ice deposited around the fan.
I had to buy a whole ASSY EVAP-REF part # DA96-00395C, and seperated the evaperator, and replaced the heater and sensor.
Spray bottle was used spray hot water to de-iced the evaperator. And salt accelerated the ice melting process.
Note: spray water to clean salt before installing new parts
