Most average refrigerators run for about eight hours per day. Multiply 8 hours of usage by the number of watts you came up with in step two, or 8 x 960 = 7,680 watts per day, on average. But 7,680 watts is only 7.68 kilowatt-hours.
Your fridge should run from around 35% of the day to around 85% of the day. A refrigerator that gets opened more frequently has to operate more often to lower the temperature of warmer items, so this amount varies. However, no fridge should run all the time.
How often should a refrigerator cycle on and off?
Every 12 to 15 hours, the refrigeration defrost cycle should begin, which uses a defrost heater to melt any frost that has accumulated on the evaporator coils. Once the defrost cycle is complete, the refrigeration cycle will begin again.
