To set the temperature on your Frigidaire upright freezer, locate the control knob inside the freezer. Turning the knob adjusts the temperature. For accurate readings, allow 24 hours for the temperature to stabilize after making any changes. If you face any issues, consult the owner's manual for more guidance. Use a lower number for a warmer temperature and a higher number for a colder one. Keep in mind that it's important to: - Check the temperature periodically with a thermometer. - Minimize door openings to prevent warm air from entering the freezer. - Keep the freezer at least half full for efficient operation. - Remember, regular maintenance, such as cleaning or replacing the gasket, plays a key role in your freezer's performance.
