Diane T Gladwin , MI April 17, 2017 Samsung refrigerator frosting up on refrigerator evaporator I ordered a new defrost sensor and defrost fuse. I am a widow and had no clue how to fix a refrigerator but with your how to video's and research I was able to do it myself. One bit of advice the frost will adhere to the plastic panel so you must let it defrost itself before trying to remove that panel. If not panel will not come off. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
