USER MANUAL SR6171

Hello John, thank you for your question. Unfortunately, we do not have the capacity of the unit. But you can follow this information to determine what size your unit is. Grab a tape measure and measure the width, depth and height of the inside of your refrigerator. Multiply the numbers together (W x D x H) and divide the total by 1728 to get the cubic feet. For example, if you have a refrigerator that measures 30" wide by 30" deep by 48" high, you multiply 30 X 30 X 48. I hope this helps.
