Safely defrosting a freezer means protecting food first and then letting ice melt without sharp tools, flame, or intense heat. Switch off or unplug the appliance as the manual directs, contain meltwater with towels, and clean and dry the interior before cooling it again.
Move food to reliable cold storage
Use another freezer or an ice-filled cooler and keep food grouped to retain cold. If food fully thaws and warms, apply food-safety rules before deciding whether to refreeze it.
Disconnect the appliance and protect the floor
Follow the manual to switch off or unplug the appliance and place trays and towels where water can escape. Do not work with plugs, extension cords, or connections in a wet area.
Let ice soften without puncturing surfaces
Do not use knives, screwdrivers, or metal objects to chip ice; they can puncture tubing or damage the liner. Do not use flame, a heat gun, or a space heater against the freezer either.
Clean, dry, and cool before reloading
Once ice is gone, clean with a compatible product, dry corners and drains, and restart the appliance. Let it return to a safe temperature before replacing food that has remained frozen.
