The three timing switches used are single- pole,
double throw (SPDT). They are identical except for
function, and can be used interchangeably.
1. H Ho olld d S Sw wiittc ch h - assures completion of a revolu-
tion once the ice maker operation has started.
2. W
Wa atte err F Fiillll S Sw wiittc ch h - opens the water valve dur-
ing the fill cycle. It is the only adjustable com-
ponent in the ice maker.
3. S Sh hu utt--o offff S Sw wiittc ch h - stops ice maker operation
when the storage container is full of Ice. The
switch is opened after the sensing arm is
raised to its most upright position. The switch
is mounted to the top right wall of the ice
maker support.

The thermal cut-out is a one-time limit fuse used
as a safety device. It is located under the mounting
plate, in the head of the ice maker, between the
thermostat and wire connector.
If the thermal cut-out opens, the cause of failure
must be determined and corrected prior to
replacing the TCO. Normals causes of the TCO
failing are a bad thermostat or a shorted coil on
the water valve.

Three separate cams are combined in one molded
Delrin part:
1. Inner cam operates shut-off switch lever arm.
2. Center cam operates hold switch.
3. Outer cam operates water fill switch.
One cam end is attached to a large timing gear.
The other cam end is coupled to the ejector.

This large molded plastic gear is driven by the
motor and, in turn, rotates the cam and ejector.
A “D” shaped hole in the gear fits over the timing
cam hub. Spacer tabs on the backside of the gear
prevent the gear from binding on the mounting
plate.
M Mo otto orr
A low wattage, stall-type motor drives the timing
gear. This gear turns the timing cam and ejector
blades approximately one revolution every three
minute (1/3 RPM).

A single-pole, single-throw switch is mounted on
the right side of the housing at the front of the ice
maker. This switch is used to turn the ice maker
off. Unlike the switch on the bail arm the on/off
switch will stop the ice maker as soon as it is
pushed, and it will not allow the ice maker to
complete the revolution.

A four-prong plug connects the ice maker wiring to
the cabinet wiring harness. The ice maker
assembly is wired across the line and will harvest
in either the refrigeration or defrost cycles. A wiring
diagram is located inside the front cover of the ice
maker.
