Sub-Zero's website provides a parts dealer locator on its website where refrigerator owners can enter their zip codes and find the nearest dealers. Amazon.com sells gaskets for Sub-Zero refrigerators, but these gaskets are not Sub-Zero manufactured parts.
Sub-Zero recommends that customers use service technicians to replace gaskets rather than do it themselves. Owners may want to find out whether a gasket replacement is covered by the warranty on the refrigerator. Sub-Zero provides a two-year warranty with all of its residential appliances that covers parts and labor.
Certified Refrigeration provides comprehensive instructions for gasket replacement on Sub-Zero 300, 500 and 600 series refrigerators, but notes that it is not an easy process.
Customers can also locate nearby service technicians at SubZero-Wolf.com.
