I am trying to find out what size this freezer is so I can replace it. Didn't know until now that others have also been suffering with this drain problem. Which is why we are going to replace the freezer. We are tired of the problem.

Ruler works. Length x width x height of compartment.

Just measure everything in inches and divide by 12 three times.

e.g. L = 72", W = 23", D = 33.5"

Volume in cubic ft = (72 * 23 * 33.5)/(12*12*12)

What's the drain problem?
