Display shows dF or DF; freezer may pause cooling during this indication.

Note: On many Igloo digital freezers, a dF or DF indication simply means the unit is in a scheduled defrost cycle and is not an error.

What to do:

• Do not unplug the freezer during a normal defrost cycle; this can extend the time needed to resume cooling.
• Allow 20–40 minutes for the defrost cycle to complete. The display should return to normal temperature readout afterward.
• Ensure the door remains closed during defrost to maintain temperature.

If dF persists for many hours:

• Unplug the freezer for 10 minutes, then plug it back in. If dF immediately reappears and cooling never resumes, the control board may be stuck in defrost.
• In that case, the main control board may need to be replaced by a technician.
