This genuine Samsung door gasket (DA97-05253T) is designed for your refrigerator to maintain an airtight seal around the door, preventing warm air from entering and compromising the internal temperature. If your refrigerator door is not sealing properly, it may be time to replace the gasket. Be sure to smooth out any folds and creases in the gasket by soaking it in warm water or using a hair dryer on low heat. Before starting the replacement, store perishable food safely. Check your device's model number to confirm compatibility.
