Genuine Sub-Zero door seals and gaskets

Sub-Zero door seals and gaskets create the airtight barrier that keeps cold air in and warm air out of your refrigerator, freezer, beverage center, wine storage unit, or ice machine. When a seal weakens, stretches, sags, loses magnetic pull, or begins pulling away from the door, cold air can leak out while warm air and moisture enter the cabinet.

Door Seal Information, Common Signs, and Ordering Help

A worn Sub-Zero door seal or gasket can cause water dripping, frost buildup, temperature swings, longer run times, wet cabinet insulation, interior rust, and swelling or warping around the liner. Moisture leaks may also lead to musty odors, mold or mildew staining in the gasket folds, slimy residue, food spoiling faster, water dripping under the appliance, possible floor damage, and higher energy use from the unit running longer. Replacing the correct door seal helps restore proper cooling performance and helps prevent costly cabinet damage.

Common signs

  • Frost buildup around refrigerator or freezer doors
  • Water dripping or moisture near the door opening
  • Cold air leaking out around the cabinet opening
  • Door gasket pulling away, sagging, cracked, torn, or stretched
  • Weak magnetic seal or loose contact against the cabinet
  • Door not fully closing, sealing, or staying shut
  • Rust staining, mildew, or odors in the gasket folds, especially if they keep coming back after cleaning
  • Longer run times, temperature changes, higher electric use, or food spoiling faster

Identify the correct seal

  • Use your model number. This is the most accurate way to match the correct seal or gasket.
  • Confirm the appliance type: refrigerator, freezer, wine storage, beverage center, drawer gasket, or full-size ice machine.
  • Check whether the seal is for the refrigerator door, freezer door, upper drawer, lower drawer, beverage center door, wine storage door, or ice machine door.
  • Door seal color is white unless the item title or description notes another color.
  • If you are not sure which seal fits, contact Parts for assistance.
