Electric refrigerator 110 with 220 voltage regulator

Electric refrigerator 110 with 220 voltage regulator. Sorry, I want to replace the refrigerator; I will get a two-door refrigerator used for 5 years, and the fridge itself is working fine, no issues except for some noise from the bottom, along with a 220 electric freezer working 100%, no defects, just that we don't need it. The price of the refrigerator is 500 The price of the freezer is 300
