Abstract: An under the counter ice making machine has a refrigerator for producing ice cube bearing slabs. A freezer compartment support means includes a bottom compartment having a rear panel extending upwardly to a top panel. The evaporator of the refrigerator is attached to the rear panel adjacent to the top panel and the remainder of the refrigerator components are supported in the bottom compartment which has an open top. A separate unitary freezer compartment includes an integrally formed ice bin portion and a top portion. When the freezer compartment is resting on the bottom compartment of the support means the top portion coacts with the evaporator bearing rear wall end to enclose the top portion. Thus, the freezer compartment is slidably mounted on the bottom compartment so that the bottom of the ice bin portion closes the bottom compartment.
