Preventing Frost or Ice Crystals on Food
How to Prevent Frost or Ice Crystals on Food
It is possible to have some ice crystal formation on items placed in the freezer. When items placed in the freezer are warmer than the freezer temperature or have condensation on them, the moisture can freeze and form ice crystals. To prevent excess ice crystal formation, use only freezer-safe containers and moisture-proof, vapor-proof freezer wrap. This wrap will help prevent moisture loss during the defrost cycle.
When the freezer defrosts (self-defrosting models only), the freezer air temperature will rise. To minimize the effect on food temperature, maintain a fully stocked freezer compartment but don't overload the freezer. If foods lose any moisture during the defrost cycle, some ice crystals will form. When the defrost cycle ends, the freezer temperature will return to the normal set temperature, depending on the freezer control setting. Control adjustments may be needed depending on environmental conditions.
Are the doors left open for long periods of time?
Frost on food can also be caused if the door is left open for a period of time. This allows humidity to enter the freezer. Make sure the door is closing completely and is not blocked by something between the door gasket and cabinet.
Are the doors opened frequently?
Frequent door openings can let in humid room air. Keeping door openings to a minimum will help, but may not completely eliminate frost or ice in the freezer. During months of high humidity (especially if a home is not air-conditioned), it is normal to see some frost and sweating on the interior walls or on food packages.
Are the doors sealing correctly?
An improper seal of the gaskets on the refrigerator or freezer doors could also cause humidity to form. Check the seal around the outside doors and the freezer door to make sure nothing is obstructing the gasket seal.
Are the controls set correctly?
Temperature controls are preset at the factory to the "mid setting" which should be correct for normal household use. If your controls need to be adjusted, adjust the temperature one setting colder and wait 24 hours for the compartments to cool. Repeat this process until the desired temperature is reached. Refer to the "Owner's Manual" for instruction on adjusting the temperature.
