Hello Chris! Newer refrigerators have smaller, more powerful, high-speed compressors that generally cost less to operate than those in older refrigerators. These compressors are designed to run 80 % to 90% of the time. This makes them more energy efficient because the greatest amount of energy used when the compressor cycles on. We hope this helps. Thank you for your inquiry on our Whirlpool appliances.
