Freezer efficiency tips
To keep your freezer in tip-top shape, follow these simple suggestions:
Keep your freezer set to -18°C.
If it's mostly empty, keep some plastic containers full of frozen water inside to help it stay cold.
Remove ice buildup on the coils. Buildup makes the compressor run longer to keep cold. Removing buildup saves an average of 10% of a refrigerator's energy, which amounts to up to 60 kWh/yr. Be sure to unplug the unit before carefully cleaning the coils.
