Your Samsung wall oven might need a new assembly door sub if the current one shows signs of damage or wear. Over time, regular use can lead to cracks or compromised seals, affecting your appliance's performance. The assembly door sub (DG94-02896C) is a genuine replacement part designed for Samsung's 30-inch smart microwave combination wall oven, smart double wall oven in stainless steel, and self-cleaning double electric wall oven. Before purchasing, verify your device's model number for compatibility.
