CU50 Service Parts
This is the illustrated parts list for the CU50 Cube
Ice Machines
When ordering a service part, always refer to the
complete model number of the equipment being
repaired to be sure of obtaining the correct part.
Many times there are slight differences between
models, and having the complete model number
will aide in selecting the correct part.
The cabinet changed in November 2014 to include
a service panel.
