Hi KK,
I'm sorry to hear the popping sounds coming for your RF28HMELBSR refrigerator are very loud. There are a variety of possible causes of these sounds, including temperature changes causing the plastic inside the refrigerator or air in the water lines to expand and contract. It's very possible that the louder sounds are related to the ice harvesting into the bucket, so I'd suggest turning the ice maker off at night or when the sound may disturb you, then back on in the morning or when you're leaving the house.
I hope this helps to alleviate your discomfort.
Thank you,
Ms. Samsung
