Sub-Zero Door Seals and Gaskets
Find factory-original Sub-Zero door seals and gaskets for refrigerators, freezers, wine storage units, beverage centers, and ice machines.
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.
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.
