Electronic Functional Description

Electronic Testing Mode

Forced Defrost Activation

1. Press Display On pad to activate control panel.
2. Simultaneously press and hold Max Ref pad and
Display Off pad for 3 seconds.

Forced Compressor Activation

1. Press Display On pad to activate control panel.
2. Simultaneously press and hold Max Frz pad and
Display Off pad for 3 seconds.

Open Thermistor Detect

If freezer or refrigerator thermistor circuit opens,
wiring to thermistor is open or low voltage board failed.
Freezer or refrigerator indicator light will glow and
temperature indicators 4 through 7 will sequence one
at a time until Alarm Off pad is pressed.
DANGER
High Voltage
1. Check for line voltage on terminal E7 on high
voltage board. With refrigerator door open there
should be 115 VAC, with refrigerator door closed
there 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 7 on pin connector
of high voltage board. Output voltage should
toggle with toggling of light switch. If output
voltage does not toggle, high voltage board needs
replacing.
3. If terminal 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 of pin connector 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 there
should be 115 VAC, with door closed there 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.
RS1200001
2. Check for voltage on terminal 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 terminal 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 of pin connector on low
voltage board) or low voltage board needs
replacing.

Keyboard Functions

Display On Pad

1. Activate control panel by pressing Display On pad.
All other pads, except for Alarm Off remain
inactive until Display On pad is pressed. Once
activated, pads remain programmable for at least
10 minutes.
2. Entry tone indicates a pad was pressed, command
was read, and accepted. Deactivate entry tone by
pressing and holding Display On pad for 3 to 5
seconds. Three short beeps indicate instructions
were accepted. Activate entry tone by pressing
and holding Display On pad for 3 to 5 seconds.
3. Activate temperature setting area of display by
pressing Display On pad.
4. Deactivate flashing lights (power up alarm) after
refrigerator is first plugged in or after power
outage by pressing Display On pad.

Warmer Pad

1. Raise temperature by pressing Warmer pad.
Temperature level raises one bar at a time. If entry
tone is active, beep will sound at each bar until top
level is reached.
2. If pad is pressed continually, temperature level will
raise at accelerated rate.
3. Activate temperature setting area of display by
pressing Warmer pad.

Colder Pad

1. Lower temperature by pressing Colder pad.
Temperature level lowers one bar at a time. If
entry tone is active, beep will sound at each bar
until bottom level is reached.
2. If pad is pressed continually, temperature level will
lower at accelerated rate.
3. Activate temperature setting area of display by
pressing Colder pad.
