Bottom Freezer Refrigerators have always been about convenience. Having the fresh food section above the freezer, bottom freezer refrigerators put the food you use most at eye level. The Express Freezing Function provides accelerated freezing up to 24 hours to produce 6 lbs. of ice (4.5 lbs. without Express Freezing) and lock-in freshness for freezing foods fast. The DuraBase is a solid freezer base that prevents frozen foods and ice from falling through a typical wire base.
