Our RS265LBWP Side by Side began making a noise a few days ago. It is a vibrating/rattling sort of sound that is coming from the mid-back area near the deodorizer. When we open the rattling sound sounds as though it is a fan of some sort rattling to a stop. It remains off until about 5 second after we close the door when it begins again. It will run as long as the door is closed but as soon as we open it it rattles to a stop.
We're sorry to hear you're encountering this issue. If your refrigerator is making a noise like a fan is hitting something, and it stops when the door is opened, your refrigerator requires service. We have further researched the issue you described and our product specialist indicates this is commonly an issue with the defrost heater.
