Ice maker, bail arm, bail arm switch, gear box, are
mounted in the front of the ice maker in a snap out
housing. The bail arm drops down to check the amount
of ice in the bucket and uses the switch to prevent ice
harvest when the ice maker bucket is full. (See Figure
4-3) The motor rotates the ice tray during harvest cycle.
The switch is used to sense the location of the bail arm
as well as the position of the ice tray during the harvest
cycle.
The rear section of the ice maker compartment contains
the ice maker evaporator, a 70 Watt defrost heater (See
Figure 4-4), a defrost bimetal limit thermostat with a
contact set that will open at 48°F and close at 25°F.
The Ice Maker defrost heater will turn on at the same
time as the defrost heater for the main evaporator
located in the freezer.
There is a circulating fan motor to supply air movement
to the ice maker compartment. It is mounted in the air
Handler which is held in place by 3 screws going into the
back of the food compartment liner.
NOTE: There are 4 screw holes in the air handler, the
bottom left screw hole is not used.
The fan motor for the food compartment ice maker is a
12V DC fan motor.
(See Figure 4-5) There is a solenoid to control the cube
ice well as the auger motor to dispense ice also mounted
in the air handler below the fan motor. The solenoid and
auger motor are both 115 V AC components.
Defrost Water Drain
The defrost water from the ice maker compartment
evaporator runs into a trough in the bottom of the drain
housing. The housing contains an aluminum shield that
covers the front of the defrost heater. The housing
slides up and around the evaporator and defrost heater
from the bottom. This housing fits inside the back of the
air handler behind the auger motor The outlet for the
trough lines up with a drain line running through the
insulation between the cabinet and the liner. The water
then runs into the same drain pan under the product
as the defrost water from the freezer evaporator. (See
Figure 4-6)
