Sensors
: The practise of testing the sensors in an ice bath is not an option with the new electronics. The
configeration of the electronics is such that there is a floating 240 volts AC in the sensor wiring. If for
any reason the insulation breaks down the sensor wiring will be live.
The 24 hour period for the 3 daily door opening maximums starts from when the cabinet is first
switched on. The door openings are sensed through the fresh food compartment door only via the light
switch. If the light bulb fails door openings are still sensed. If the light switch fails on the electronics
will default to 6 hours of run time between defrosts. If the light switch fails off the time between
defrosts will be set by heater on time only and may cause defrost problems if there are large numbers of
door openings.
Automatic Ice and Water:
A cubed/crushed ice feature on the User Interface (Control Display) allows
the user the choice of crushed or cubed ice. On selection place a container under the chute and press the
ice paddle. 6 LED lights illuminate the dispenser area and the cubed/crushed ice is delivered down the
chute.
To obtain chilled water, place a container under the water dispenser and press the water paddle. 6 LED
lights illuminate the dispenser area and the chilled water is supplied via the dispenser chilled water tube.
The 6 LED lights remain on for 6 seconds after the paddles are released.
Lamp On/Off: Illuminates the dispenser area using the 6 LED lights.
THERMAL FUSE
On the Electronic models defrost timing is 6 to 22 hours of compressor run time, followed by 10
minutes of fan run only. During this 10 minute period the damper is open to drop cold air from the
freezer into the food compartment. This warms up the temperature of the evaporator and decreases the
length of defrost time.This is followed by the lesser of a 35 minute defrost period or heater on time plus
4 minutes drip time. The heater on time is determined by the defrost termination thermostat (DTT). The
defrost heater on time is sensed through the defrost heater and the DTT. The fan is delayed from starting
for 5 minutes after defrosting (after drip time), to allow the refrigeration system to pull down to
temperature, but must start when cabinet is first turned on.
If the Heater Triac on the Control Board or the D.T.T. fails the circuitry relies on the Thermal Fuse to
safeguard the refrigerator, therefore it is ESSENTIAL that the Thermal Fuse is always replaced with
the same type if it fails.
