Hitachi refrigerator 21 feet. The refrigerator is almost new but has a defect in the heater. The freezer's cooling is excellent, but the cooling below the refrigerator is weak and needs a heater replacement according to the engineer. If the electricity is disconnected and restarted, it cools excellently, including the bottom of the refrigerator, for five days. When ice accumulates in the freezer, the cooling below the refrigerator weakens. For sale to the highest bidder.
