OSAKA -- In this week's second revelation concerning defective products, Sanyo Electric Co. announced Friday that it will replace, free of charge, parts of refrigerators sold from 1995 with doors that could fall off.

The major consumer electronics maker made public the defects four years after it first received complaints from consumers.

Sanyo said it has received 139 reports of refrigerator doors coming off their hinges and falling to the floor. In some cases this resulted in injuries to customers and damage to goods.
