Samsung is the most reliable refrigerator. However, their ice maker will need to be repaired like the others over time and almost certainly within 3-5 years. Samsung went from nowhere 10 years ago to being the number 1 sold brand last year. There are issues with support from that type of expansion.

10 for electricity per kWh, that means the aging refrigerator is costing you about $. 55 per day, $16.67 per month, and $200 per year. A modern-era Energy Star-rated fridge, by comparison, might only use 350 kWh annually. At the same $.

Newer refrigerators have compressors that are designed to run 80% to 90% of the time. This makes them more energy efficient because the greatest amount of energy is used when the compressor cycles on as opposed to when the compressor is actually running.

However, as with a lot of inventions, the first inventor was not the one who made the device practical. In 1873, Zenobe Gramme, a Belgian inventor, invented the first commercially practical (one which could be made reliably and cheaply enough to sell commercially) electric motor.

Refrigerators work by causing the refrigerant circulating inside them to change from a liquid into a gas. This process, called evaporation, cools the surrounding area and produces the desired effect. You can test this process for yourself by taking some alcohol and putting a drop or two on your skin.
