Self Diagnosis: Press both buttons
(Energy Saver– Lighting) simultaneously (No
sound when both buttons are pressed at the
same time) ‟til the display quits blinking and
beeps, 8-12 seconds, then release and read
Fault Codes.
This will also cancel the Fault Mode created
by self-diagnosis at power up.
Forced Mode: Press both buttons (Energy
Saver– Fridge) simultaneously (No sound when
both buttons are pressed at the same time) „til it
beeps and goes blank, 8-12 seconds

DC FAN MOTORS
Brushless DC Fan motors are used to save energy. The fans operate at two speeds. Fan speed information is read by
the Main PCB. If the fan speed exceeds 600 RPM or the speed is too slow, or stopped the fan drive circuit is disabled,
After 10 seconds the circuit tries again with 3 seconds of DC voltage If the fan continues this activity for 5 cycles, 10
seconds off 3 seconds on, the fan drive circuit is disabled for 10 minutes.
TO TEST THE FAN CIRCUIT VOLTAGE.
Power off and back on to check the DC voltage to the motor, wait from 10 to 60 seconds for the fan voltage to kick in,
and then check fan voltage, the average reading is 9 VDC. If you get 3 seconds of voltage every 10 seconds for the 5
fan power up cycles, then the Main PCB is good.
NOTE: You may need to put unit in FORCED FREEZE mode to activate the fans/compressor.
If the fan blade is blocked by ice, then defrost and check the motor again, after removing power from the unit.
If the evaporator is ice blocked and thus blocking the air flow, the fan will over RPM and is stopped. Remove ice and
check the motor again. If everything is clear around the fan blade then the motor would be at fault. Continuous fan errors
will be displayed on the front panel display. PLEASE NOTE: The door switches control the evaporator fan motors. Have
them closed to test the motors. Delay time 10 – 60 seconds.
Heat Release Ice Makers
Heat Release Ice production Explanation
38 minutes after the water fill is complete, the control
board will check the temperature of the eject Thermistor,
on the Ice Maker Head, if the Thermistor reads a temperature lower than 18.5 degrees for more than 5 seconds, then the ice production process is completed. The
Ice maker will harvest if the ice bucket is not sensed as
full. If a Fault Mode is detected with the Ice Maker operation, the Ice Maker stops working for 3 hours. Which
means, the Ice Maker checks the operation every 3
hours until it works properly.
FREEZER TEMPERATURE CONTROL BY THE ICE MAKER
Interior Temperature of the freezer will be set to -14 degrees Fahrenheit until the ice bucket is full. When the ice
bucket is full, the freezer will maintain original set temperature. Also, whenever the ice is used, the freezer will
again set to -14 degrees Fahrenheit. Selecting "Ice Off” will allow the freezer to be controlled by the set tem-
perature. If water is not hooked up, the freezer will always be at –14 unless “Ice Off” is selected.

Heat Release I/M Test Mode
Press and hold the ICE TEST S/W for at least 1.5sec, the
harvest function will start. If the ice maker Thermistor is below 0 degrees the Ice maker heater turns on for about 2 minutes. If the temperature exceeds 0 degrees, Ice maker
heater turns on for 30 seconds. After the Ice maker heater
turns on for 30 seconds, the heater turns off and then Ice
maker harvest motor turns on. The motor will rotate in right
direction for about 3 minutes, after this, water supply valve is
turned on, then the valve is turned off, the test mode is completed. If the above operation is not carried out within 6 minutes, it will go into a fault mode.
