Introduction Specifications and Overview
Sixth Sense Technology
6th Sense software makes an estimation of
the actual food temperature inside the
refrigerator and freezer compartment and
adjusts cooling to allow the food packages to
return their initial temperature faster during
pull down, door openings, or heavy food load.
6th Sense algorithm runs in both FC and RC
and each contains 3 routines: Trigger,
Package Estimator, and Defrost Manager.
• Trigger routine is executed every 2.5 seconds while Package Estimator and
Defrost Manager are executed every 10 seconds. The trigger routine is divided
into two subroutines: door monitoring and temperature monitoring.
Trigger parameters and performance parameters reside in the UI board, the
actual 6th sense algorithm resides in Gemini Flash board.
• Package Estimator routine computes an estimation of food in FC and RC
according to Thermistor reading and door status. Package estimator is run when
the User Interface sends the required parameters to Gemini flash and sets the
6th Sense Enable bit to true. If 6th Sense is needed, it will call for additional
cooling by turning on compressor, damper and evaporator fan.
• Defrost manager is composed of two main states: Normal and 6th Sense.
When 6th Sense routine is active, defrost will be inhibited based on the control
parameters settings to allow food temperature recovery.

Ice Maker – Emitter /Receiver Boards
The emitter board emits an infrared beam. When
the eye on the receiver board sees the beam a
circuit is completed indicating the ice bin is in place
and not full. This signal is sent to the control board
and the ice maker is energized. If the beam is not
seen by the receiver board, the control board shuts
off the ice maker.

Ice dispenses from the ice maker storage bin in the freezer when the
dispenser lever is pressed. The ice maker can produce both crushed and
cubed ice. Before dispensing ice, select which type of ice you prefer by
pressing the ICE MODE button. The display screen indicates which type of
ice is selected. See figure 10.
For crushed ice, cubes are crushed before being dispensed. This may cause
a slight delay when dispensing crushed ice. Noise from the ice crusher is
normal, and pieces of ice may vary in size. When changing from crushed to
cubed, a few ounces of crushed ice will be dispensed along with the first
cubes.
NOTE: Ice may continue to dispense for up to 10 seconds after removing the
glass from the lever. The dispenser may continue to make noise for a few
seconds after dispensing.

Starting Device Operation
The starting device is an assembly consisting of
an overload (1) and a PTC relay (2). The PTC
relay is composed of a semi conductive
substance formed in the shape of a disk (2). The
disk is connected in series with the run and start
terminals which in turn connect to the run and
start windings. The resistance of the disk
material is relatively low at room temperature.
When voltage is applied and current flows to the
compressor windings, the current flowing to the
start winding heats the disk material. As the
temperature of the disk increases, the resistance
of the disk increases rapidly and limits current
flow to the start winding. At the same time current
flow through the disk is decreasing, the effects of
current flow through the run capacitor increases.
This change in current and capacitance seen by
the start winding helps start the compressor and
allows the start winding to remain in the circuit
once the compressor is running.

Note: Do not disassemble the PTC device. The PTC device (2) was opened to
show the interior construction and to assist in explaining the theory of operation.
Checking the PTC: The easiest way to check the PTC device is to replace it
with a known good one. If a new PTC device is not available, a resistance check
can be made.
1. Unplug the refrigerator
2. Disconnect the starting device from the
compressor.
3. Unplug the run capacitor form the
module.
4. Connect an Ohmmeter across the L
and S terminals.
5. If the PTC is at ambient temperature,
70 – 80 degrees F., the approximate
resistance should be between 3 and 10
OHMs. An infinite reading indicates the
PTC device is open.
