This paper deals with the issue of door height difference (DHD) which occurs for SBS refrigerator necessarily. In order to identify the cause of DHD, analysis of refrigerator structure and entire process from door manufacturing to usage have been investigated. From diverse experiments, it was found that the flatness of the floor was a main causing factor. In order to decrease the DHD , the effects of 6 design parameters to control of cabinet deformation have been investigated by using DOE(design of experiment) and finite element analysis. Based on the correlation equation, it was possible to estimate the DHD for new refrigerator design.
