I'm sorry to hear you're having a problem with your RS253BASB. Please try raising the temperature in your refrigerator. Samsung recommends setting the temperature to 38°F, but it can be set as high as 46°F depending on your needs. If there continues to be ice forming in the back of the fridge and nothing is blocking the vents, your RS253BASB may require service. To initiate service through Samsung, please submit an online service request through the link below, or call 800-SAMSUNG to speak with an agent who will be happy to assist you.
