In this paper, we describe fire risk of Kimchi refrigerator. The Kimchi refrigerator has been widely spread and used starting from the first half of 2000 and recently fire accidents caused by the Kimchi refrigerator emerged as social concern. In particular, in products of a specific manufacturer, it is not an environmental factor, but a characteristic that the fire is caused due to a defect of the product itself is shown. These features are judged to be formed by unique defects regardless of external factor by forming electrically arc mark in the relay element. In this paper, we analyzed the cause of the fire occurring in the Kimchi refrigerator and finally confirmed the characteristic that the fire occurred mainly in the relay element due to insufficient capacity of the relay element. Therefore, when a fire occurs in a product of the same maker as the Kimchi refrigerator mentioned in this paper, it is always judged that the inspection of the relay element should be carried out.
