I have an RSN8210S9 fridge freezer, and have for some time noticed that we seem to have what I consider to be high energy usage on the smart meter when we are out of the house or overnight when nothing is used. To test this I have been using an energy monitor plug to keep an eye on the power consumption of various devices.
As a base of comparison we have a standard under counter freezer as well, which seems to use around 0.6kWh per 24 hour period.
The Samsung fridge freezer appears to be run at 150-250w constantly. Based on that usage the unit will be using around 4kWh a day (1460a year which seems to be along way off the quoted 450 a year on the energy label) I have checked the obvious things like the gap at the back of the unit, and the vents. The temps were set to 4 and -21, but I have changed them to 5 and -17 to see if that makes a difference. I can also hear something that sounds like a fan/motor/fluid from a 4 or 5 m away.
Is this normal behaviour, or is it time to call under the warranty?
