The data of failed product in marketplace is very important one which understands the use environment of customer. To improve reliability of the product, the failure analysis of the product should be performed. In this study, we investigate the failure mode of helix ice dispenser in side by side refrigerator. To perform failure reproduce examination of helix ice dispenser, accelerative life test(ALT) was adopted. The result of ALT was identical with failure of the helix in marketplace. The cause of failure in helix ice dispenser was cracked and fractured by helix upper made of polycarbonate. The design of helix upper and blade dispenser was modified. The helix dispenser with new design could guarantee 14.8 years of B₁ life under worst conditions.
