There are many reasons why ice can build up inside your refrigerator. Although some of this buildup is normal, if you notice ice on the inside of your refrigerator, it should be removed as soon as possible. Sometimes it is simply a matter of cleaning and defrosting the device. Other times, the problem could be more severe that requires repair.

A common cause of ice build-up inside your refrigerator is an incorrect temperature setting. This could be the result of an improperly adjusted defrost cycle. Most commercial refrigerators have a control panel with temperature settings from LOW to HIGH, as well as numeric settings from one to 10. Be sure to adjust the freezer temperature to 0°F.

Ice buildup can also be a sign of a damaged package seal. As your commercial freezer ages, the seals will likely break, allowing warm air to enter and cold air to escape. Other causes include worn insulation or a malfunctioning evaporator coil.

Another common cause of ice buildup in walk-in freezers is warm, humid air. When this happens, the freezer is more prone to freezer burn, which can ruin frozen food and spoil its taste. This is why it is so important to avoid leaving the door open to restock or dispose of food.
