RF221NCTABC 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.

OPENED THE LEFT SIDE REFRIGERATOR DOOR WHERE THE DEFECTIVE MECHANISM WAS. GOT UP ON THE FIRST STEP OF THE STEP STOOL,REMOVED THE PHILLIPS HEAD RETAINING SCREW FROM THE BROKEN PART.PUT THE NEW CLOSING MECHANISM IN PLACE AND RE-INSTALLED THE PHILLIPS HEAD SCREW. STEPPED DOWN FROM THE STEP STOOL AND SHUT THE REFRIGERATOR DOOR.

Interestingly, the few authorized samsung parts suppliers I found declared that this model did not have a lower icemaker, whereas this company actually had the specific part. The heater swap is completely straightforward, and simple, but for one detail. The insulation wrap is easily torn when pulling the tube out and my time was spent finding a suitable material to patch the hole. I would recommend purchasing a new tube with heater element and wrap pre-installed. This issue in no way diminished my satisfaction with the product or the prompt delivery time.
