RF22K9381SR ((AA)(0008)) 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.

After watching a few you tube videos on the Samsung ice maker removal, this repair was not that bad. The key to this repair is PATIENCE!
Unplug your fridge, have a steamer and Phillips & straight screw driver handy. Remove ice bucket, place rags or paper towels in bottom half of ice maker. Fire up your steamer and melt ALL ice before proceeding! Once all ice is gone, remove one screw to the left on cover for the wiring, remove plastic wire cover , remove screw just below ice maker itself, push locking tab in to release plastic lower tray attached to bottom of ice maker. Once you do this it exposes the refrigerant line (u shaped) under ice maker. If you can still see ice once that plastic cover drops down, yep... more steaming , if you try chip away any remaining ice damage will result to that refrigerant line then it’s game over. Fridge needs to be replaced! Once fully clear of ice , carefully pry that refrigerant line down a bit so it is released from the bottom of ice maker. Do not bend it down too far only enough so it will clear when pulling ice maker out. Un clip yellow electrical connector to ice maker and gently pull the ice maker towards you and down to fully remove. As you are pulling it out be sure refrigerant line does not get hung up. Once removed you may find more ice build up on top of auger assembly. All ice/ frost needs to be gone. Follow u shaped refrigerant line back towards the styrofoam, push one clip on each tube towards the back with the tab facing down! The plastic rectangle trim piece slides off fairly easy. This web page gives detailed pictures on what to expect, as there could be other issues in that ice compartment that need addressed! https://edmondappliancerepairokc.com/samsung-french-door-ice-maker-frosting-up/
