Research has shown that older refrigerators consume over 20 percent more electricity than new refrigerators, making it a bad option for someone who wants to save money on electricity bills.

The question now is why old refrigerator consume more electricity, the reasons include;

1. Non- Working Thermostat: the thermostat is the part of a refrigerator that is responsibly for cooling the inside compact; the thermostat works with condenser and compressor to ensure that the inside compartment is kept cool. When the thermostat is not in a good working condition, the compressor and the condenser takes up more electricity to keep the inside compartment at the desired cold temperature and most times you find out that the thermostat in these older refrigerators are not working.

2. Older Technology: Older refrigerators were manufactured with old technology and equipment that is why they consumed more power to function well; but these days better technological improvement have been made on newer refrigerators to make them consume over 20% less power than the older ones.

3. Leakage: One common sight you find around an older refrigerator is that there is constant leakage of water and/or refrigerant. One of the factors that can lead to this leakage is if the refrigerator has a clogged or freezing defrost drain. If the defrost drain freeze, water will overflow the drain an drip down to the bottom of the compartment; after it accumulates enough water than it can hold, water will begin to flow on the floor. Old refrigerators take more power to keep the defrost drain from freezing up.
