Electronic Testing

Electronic Testing Mode

Forced Defrost Start

1. Press pad to activate control panel.
*
2. Simultaneously press and hold Max Cool and
Display Off pads for 3 seconds.

Forced Compressor Start

1. Press pad to activate control panel.
*
2. Simultaneously press and hold Fast Freeze pad
and Display Off pad for 3 seconds.
Open Thermistor Detect
Alarm sounds and freezer or refrigerator indicator light
shows and temperature indicators 4 through 7 will turn
on in sequence if either thermistor circuit opens. Refer
to Temperature Control Operation Section and
Electronic Testing Section.
1. Press Alarm Off pad to turn off alarm.
2. Alarm will retest for normal operation. If condition
has not been corrected, alarm will sound again.

Evaporator Fan Suppression

The evaporator fan will turn off every time either
refrigerator or freezer door is open.
To test if this function is operating:
1. Perform forced pull down procedure as noted
above–evaporator fan should be on.
2. Open the refrigerator or freezer door–the fan
should turn off.
3. Push the light switch off–the evaporator fan
should start.
If fan does not toggle off and on when refrigerator
light switch is turned off and on and it has been
determined evaporator fan motor is operational,
perform following tests to determine failure:
DANGER
High Voltage
1. Check for line voltage on terminal E7 on high
voltage board. With refrigerator door open
(refrigerator light ON) reading should be 115
VAC. With refrigerator door closed (refrigerator
light OFF) reading should be approximately 0
VAC.
If voltage does not change with light switch and
light switch is turning light off and on, red/white
wire is broken between switch and high voltage
board.
2. Check for voltage on terminal E7 on high voltage
board. Output voltage should toggle with toggling
of light switch. If output voltage does not toggle,
high voltage board needs replacing.
RS1300003 Rev. 0
3. If terminal 7 on high voltage board changes with
opening and closing of door, orange wire in low
voltage harness is broken (check for continuity
between pin 7 on high voltage board and pin 10 on
low voltage board) or low voltage board needs
replacing.
DANGER
High Voltage
1. Check for line voltage on terminal E8 on high
voltage board. With freezer door open, reading
should be 115 VAC. With door closed, reading
should be approximately 0 VAC. If voltage does
not change with light switch and light switch is
turning light off and on, violet/white wire is broken
between switch and high voltage board.
2. Check for voltage on pin 7 on pin connector of
high voltage board. Output voltage should toggle
with toggling of light switch. If it does not toggle,
high voltage board needs replacing.
3. If voltage on pin 7 on pin connector on high
voltage board changes with opening and closing
of door, orange wire in low voltage harness is
broken (check for continuity between pin 7 on high
voltage pin connector and pin 10 on low voltage
board) or low voltage board needs replacing.
