If your freezer continues to have frost build-up after you have replaced the gasket, below are other possibilities of this issue.

• Are foods properly covered when placed into your freezer? Foods, especially liquids or moisture-rich foods left uncovered can easily cause frost in your refrigerator. Keep all foods tightly covered and allow them to temp before you place them into your freezer. This means to allow hot foods to come down in temperature before placing them into the appliance.
• Are your drains free and clear? Freezers drain excess water down into these drains. If the drain is clogged, this can be a problem for the water. Where else can it go? It frosts up in your freezer because of its exposure to the cold. Simply cleaning the drain and making sure it is open will do all the work you need it to.
• The defrost timer may not be working. When all of these other situations prove fruitless, it could be that your freezer has a defrost timer that simply is not working or not working correctly. You can replace the timer yourself, with a bit of skill. Or, you may want to call a professional to have this done.
• The heater or the thermostat may not be working or damaged. These regulate the temperature in the freezer and therefore could potentially cause a frost situation when they aren’t working properly. Here you may need a professional to handle the repair or replacement of these parts.
