RH22H9010SG ((AA)(0002)) Samsung Refrigerator - Overview

This is the Samsung French door refrigerator style that so many people have complained about freezing up and not cooling the top section. I first changed out the defrost thermostat and this did not correct the problem. I done a quick resistance check on the temp sensor that's mounted on the evaporator itself. The resistance would change when holding an ice cube on the sensor so I just assumed it was ok. PLEASE TAKE NOTE: When performing a resistance check on this sensor, make sure your readings match the Samsung temp/resistance chart in their literature. My sensor was way off calibration and was causing the freeze up. Its working as designed now and DW is happy again. Learn from my mistake.

replaced ice "bucket"..snapped out old one, snapped in new

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.
