RF221NCTABC (AA-01) 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.

I watched several repair videos and decided I could do this because I have been doing mechanical work for over fifty years.The videos convinced me it needed replaced it is a 2009 model I bought new. I ordered the new part from parts select it came in 3 or 4 days.The hardest part was removing the freezer door and reinstalling when I was done.That wasn’t complicated just awkward.Removing the ice maker was simple and replacing it with the new one was easy.There was a protective plate on the front of the old one that wouldn’t fit on the new one.So I left it off.So far it has been working very well.
