The door seal on your freezer keeps the cool air inside and prevents outside air from seeping in. Over time the seal can become loose, cracked or damaged, causing air to escape, making the food inside your freezer expire early and causing an ice build-up. This replacement white magnetic seal measures 520 x 563mm. Important: Please be aware these seals need some manipulation to install correctly. If in any doubt please arrange for a professional technician to install this item.
