Freezer
Refrigerator Air Flow
Cold air is circulated into the compartment by the evaporator fan. When cooling is required, the main board opens the damper and turns on the fan to push cold air from the evaporator up and out the air tower. The air circulates through the refrigerator compartment and is pulled back to the freezer below the evaporator by the way of the air return passage behind the evaporator.
That warm moist air then gets pull back across
the evaporator coil to extract the heat and moisture.
Freezer Air Flow
Cold air is circulated in the freezer by the evaporator fan. When cooling is required, the main board turns on the fan to circulate cold air from the evaporator through the evaporator cover.
The air is pulled back to the evaporator through
two ducts built into the bottom of the evaporator cover. That air then gets pulled back across the evaporator coil to extract the heat and moisture.
Ice Box Air Flow
Freezer air is circulated into the ice box by the ice blower fan located in the freezer. The blower pushes freezer air up and through the top ice box air duct. Air in the ice box is then forced out through the return air passage (bottom air duct) to mix and be circulated with the rest of the freezer air.

Humidity Sensor Board
The Humidity board is located under the center of the top interface. The humidity sensor on the board provides the main board with relative humidity percentages based on the feedback voltage (see table below). The feedback voltage will range between 1 to 4 VDC. The relative humidity percentage is used to determine the articulating mullion heater on time (the greater the humidity, the greater the heater run time).
Relative Humidity Voltage (DC)
20% 1.5 V 50% 2.3 V 80% 3.1 V
Humidity Sensor Board Diagnosing
Before changing the board, ensure the proper voltages are going to the humidity board. Humidity sensor voltages can be checked at the humidity board or main board.
Connector on Humidity Board
• Orange to tan/black: 13 VDC
• Orange to white: 13 VDC
Humidity Sensor Board Removal
1. Place the top interface in the service position (see Top Interface Removal, under Top Interface in this section of the service guide).
2. Remove one 1/4 in. hex-head screw and disconnect the wiring harness.
RJ45 Connector
The RJ45 connector is mounted to the humidity
sensor board inside the top interface and is only available with the humidity sensor board. The RJ45 connector is the access point to update software using a software update module (SUM) or connect a service diagnostic tool.
Ambient Thermistor
The ambient thermistor is located under the top
interface. The thermistor clips into the backside of the top interface and is used to determine the
o󰀨set temperature of the refrigerator.
• White or tan/black to red/white: 5 VDC
• Yellow to red/white: 1 - 4 VDC
NOTE: 0 or 5 VDC from yellow to red/white
may indicate a bad humidity sensor. Replace the humidity board if there are no open or shorted wires to the board.
Connectors on Main Board
• J4 pin 4 (orange) to J4 pin 5 (tan/black): 13 VDC
• J4 pin 4 (orange) to J2 pin 3 (white/silver): 13 VDC
• J5 pin 5 (red/white) to J4 pin 5 (tan/black) or J2 pin 3 (white/silver): 5 VDC
• J5 pin 5 (red/white) to J5 pin 6 (yellow/
white): 1 - 4 VDC
NOTE: 0 or 5 VDC from J5 pin 5 to J5 pin 6 may
indicate a bad humidity sensor. Replace the humidity board if there are no open or shorted wires to the board.
The o󰀨set temperature is the temperature the
main control targets. Air temperature inside a compartment is typically lower than the thermistor reading due to cabinet thermistors proximity to cabinet walls. The main control increases the
o󰀨set temperature when the ambient temperature
increases.
To access the thermistor, place the top interface
in the service position (see Top Interface Removal, under Top Interface in this section of the service guide).
To test or replace the thermistor, follow the steps
in the Thermistors section of this service guide.

FF Door Switches
The FF door switches are AC volt switches that
have Normally Closed contacts (N.C.). The switches are actuated by the top of the doors to tell the main board to turn the refrigerator LEDs
on or o󰀨.
FF Door Switch Diagnosing
When one of the doors are opened, the switch contacts are closed allowing 120 VAC to travel to
the main board. When closed, the doors engage the switch to open the switch contacts, breaking the 120 VAC circuit to the main board.
3. Disconnect the wires from the desired switch.
4. Push in on the plunger of the switch.
Switch Not Pressed (Door or Doors Open)
J7 on Main Board
• Pin 6 (purple/white) to pin 9 (orange): 120 VAC
