To Move Control Box
1. Disconnect electrical power.

holding the control box to the base, just below the
purge switch.
4. Pull the control box forward about an inch.
5. The control box may now be moved up the
height of the control box, be careful not to kink any
capillary tubes.

Cube Size Control (bridge thickness):
Before replacing the cube size control, it should be
positively determined that it is at fault.
Check the operation of the cube size control by
unplugging the water pump, removing the right
front grill and control box cover, and watching the
Timed Freeze Light. With no ice on the evaporator,
switch the ice machine to ON. The temperature of
the suction line where the cube size control bulb is
located should be about 8-10
o
F. about 2 minutes
into the freeze cycle (with the water pump
unplugged). Or the low side pressure should be
about 31-32 PSIG. The cube size control should
then close its contacts and cause the Timed
Freeze Light on the control board to be ON. If it
cannot be adjusted to close at that point, or if it
does not open when warm, replace it.
1. Disconnect electrical power.
2. Remove the hood, door and ice storage bin.
3. Remove the control box cover.
4. Locate the cube size control.
5. Remove the two screws holding the control to
the control box, and lift the control out.
6. Pull the two wires off the posts of the cube size
control.
7. Follow the capillary tube of the cube size control
and remove it from the grommet in the back of the
control box.
8. Locate bulb on suction line and remove
insulation covering bulb.
9. The end of the cube size control is inserted in a
socket attached to the suction line. Pull it out of the
socket.
10. Replace the cube size control with the proper
part number, following the above steps from 9-1.
Be sure to re-insulate the cube size control bulb.
