Refrigerators, including French door models, typically last between 14 and 17 years, although their construction can lengthen or shorten this time. In addition, proper maintenance can extend the life of most refrigerators, including French door models.
French door refrigerators operate on the same principles as other designs and many of their mechanical components are the same as other models. Proper maintenance is essential for keeping a refrigerator operating well, so it's worth reading the owner's manual for guidance. In general, refrigerators should be placed several inches in front of walls to ensure proper air flow around the unit. Regular cleaning can also keep parts from breaking prematurely in addition to ensuring a tight seal when the door is closed, which saves on energy costs.
