RF4287HARS 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.

OMG seriously! I stopped into my go-to appliance repair shop to ask about what might be needed to repair the problem with my refrigerator door. They said you will need to replace the Mullion Flap piece. Cost would be $250-300 with part, labor and service. I went on line to see if I could handle the repair process myself. I found a How to - U Tube video and turns out I only needed to replace a little spring and pin not the whole Mullion Flap. Went to Parts select, ordered the spring and pin and did the repair myself in about 5 minutes. Shipping was $7 so I ended up paying $13 total.

The installation video notes that the door mullion spring has a bent end, and that the bent end of the spring is to be inserted into the LOWER hinge. However, on my refrigerator door, the bent end of the door mullion spring must be inserted into the UPPER hinge in order for the door to function properly. (Also noted that in your video the installer manually closed the door mullion rather than just closing the refrigerator door, another indication that the installation of the spring was incorrect.) After watching the video several times to confirm I was installing the door mullion spring according to the video instructions, I tried inserting the bent end of the door mullion spring into the upper hinge, which proved to be the correct installation of the door mull spring. What should have been a 5 minute repair turned into an ½ hour repair.
