The recommended temperature for a freezer is -18 °C. If you’ve set the temperature right but the food is still defrosting, see if one of the following will solve the problem.
Avoid opening the door too frequently or keeping it open for long periods
Your freezer needs to keep the air inside the freezer at a certain temperature to be able to keep food frozen. If the freezer door is opened too frequently or is kept open for long periods, warm air will enter the freezer and will increase the air temperature inside.
Check for frost build-up
Check your freezer for frost build-up. If the inner walls have visible frost on them, your appliance might not be reaching its ideal temperature. In this case, you’ll have to manually defrost the freezer.
