When your refrigerator starts to form ice on the inside walls, it may be due to the Second Law of Thermodynamics. The second law states that heat flows from a hotter object to a cooler object. A simple example of this principle is when ice melts. Cool the substance and more heat will be lost.
Ice build-up can also be caused by a faulty temperature sensor or a bad ice timer. Regardless of the reason, you should seek professional help as soon as possible. There are several reasons why ice can form on the interior walls of a commercial refrigerator.
A faulty seal can be blamed. A poorly sealed refrigerator door can allow hot air to enter the refrigerator, which can cause ice to form on the interior walls. If you suspect a seal problem, try moving some of the freezer items before closing the door.
You can also lower the temperature inside. A well-functioning refrigerator should maintain a temperature of -18 degrees Fahrenheit. Check the temperature inside the refrigerator once a month. Another cause of frost on the interior walls of commercial air conditioners is clogged ducts. Excess water can collect in streams and eventually turn into ice. Clogging the drain can be done by pouring hot water down the drain or by using a piece of wire to push the waste down the drain.
If the problem persists, it may be due to a humid room environment. High humidity will cause frost to form on the interior walls and will cause the food packaging to sweat. You should also avoid blocking the air vents between the refrigerator and freezer. If blocked, moisture and temperature will continue to affect the interior walls of the commercial refrigerator.
