Door Closure Mechanism
The door closure mechanism uses a spring to
provide positive door closure from 30 degrees.
The door closure mechanism actuator arm has a
spring attached to the rear and is supported by
guide rollers on either side of the base channel.
The roller circumferences and the actuator arm
detents are matched for smooth operation. The
arm is attached to the door with an Allen head
shoulder bolt.
The closure mechanism allows easy opening to
approximately 90 degrees, where the arm has a
detent to permit the door to remain open at 90
degrees with minimal tension. Once the door is
opened beyond 90 degrees, the closure
mechanism pulls the door open until the closure
arm engages the door stop at approximately 130
degrees. The reverse action occurs when the door
is closed.
Note: The door closure mechanism and the top
door hinge are held by the same bolts. Take the
necessary precautions to secure the fresh food
door when the door closure mechanism is being
removed.
•The actuator arm is spring loaded with moderate
spring tension.
To remove the door closure mechanism
1. Remove the 3/16-in.Allen head bolt and
spacer from the door and actuator arm.
2. Disconnect the spring from the pin on the top
of the cabinet and pull the actuator arm from
the closure mechanism.

–16 –
The evaporator fan utilizes a permanent magnet, 4-pole, DC motor that can operate at three different
speeds: high, medium, and low (medium and low are the same speed, controlled by the main control
board). The speed of the fan is controlled by the voltage output from the main control board. Voltage
output from the control board to the fan is 12.6 VDC; however, in order to regulate the speed of the fan,
the control board uses Pulse Width Modulation (PWM) during low speed and medium speed operation.
When operating in low and medium speed, voltage is sent in pulses (much like a duty cycle) as
opposed to an uninterrupted flow. This pulsing of 12.6 VDC produces effective voltage being received at
the motor, which is the equivalent to a reduction in voltage. Fan speed will be selected and maintained
by the control board regulating the length and frequency of the 12.6 VDC pulse.
One complete revolution of the motor is comprised of all 4 poles. To determine the rpm of the fan:
Measure the frequency being applied to the motor. Multiply this number by 15 (60 seconds divided by 4
poles). For example, a frequency measurement of 200 Hz multiplied by 15 would show a fan speed of
3000 rpm (15 x 200 = 3000). Temperature may cause some fan speed variation. Fan speed may vary
+/- 5%, depending on the temperature, with higher temperatures causing slightly higher speeds.
The evaporator fan motor uses a 4-wire connection, utilizing a common wire (white), feedback/rpm
wire (blue), supply wire (red), and a signal wire (yellow).

White Wire (DC Common)
The white wire is the DC common wire used for
testing. During repairs, DC polarity must be
observed. Reversing the DC polarity will cause a
shorted motor and/or board.
Red Wire (Supply)
Each motor uses an internal electronic controller
to operate the motor. Supply voltage from the
main control board remains at a constant
12 VDC.
Blue Wire (Feedback/RPM)
The blue wire feeds rpm (speed) information to
the main control board, allowing the board to
maintain consistent fan speeds. Loss of feedback
from the blue wire will result in the fan accelerating
to maximum speed. Measure the fan rpm using
the frequency between the blue and white wires.
Note: Fan operates at the same speed in low and
medium.
High speed - 195 to 200 Hz
Medium speed - 145 to 160 Hz
Low speed - 145 to 160 Hz (same as medium)
Yellow Wire (Signal)
The yellow wire is the input wire from the main
control board. The main control board provides
8.1 VDC effective voltage for low speed, 8.1 VDC
effective voltage for medium speed, and 12.6 VDC
for high speed. The fan will operate in low speed
only when the fresh food thermistor is satisfied.
Note: When testing these motors:
•You cannot test with an ohmmeter.
•DC common is not AC common.
•Verify 2 voltage potentials:
a. Red to white - power for internal controller.
b. Yellow to white - power for fan.
•Observe circuit polarity.
•Motors can be run for short periods using a
9-volt battery. Connect the white wire to the
negative (-) battery terminal only. Connect the
red and yellow wires to the positive (+) battery
terminal.

Condenser Fan
The condenser fan utilizes a DC motor that operates
at a single speed and is mounted in the machine
compartment. When the fan is operating, air is pulled
through the condenser, drawing air through the coils.
The air is then exhausted past the compressor and out
the front of the refrigerator on the right side.
Inlet air is available through the left front and left rear of
the machine compartment.
If the fan shorts, it will damage the main control board.
If the resistor on the main control board is burnt, you
must replace the fan and the board (see photo page 15).
The condenser fan is mounted with screws to a fan
shroud and mounting bracket in back of the
condenser.
