Yes, leaving the freezer door open can cause frost build-up. The warm air from outside mixes with the cold air inside, leading to condensation that then freezes. To prevent this, ensure the door is always tightly closed and check the door seals regularly. If frost has already formed, you may need to defrost the freezer to remove it.
