There are several diagnostic modes available to the service 

technician to assist them in diagnosing product faults.

●

●

To enter diagnostic mode, press and hold the   and   

buttons together for 4 seconds.

●

●

The temperature LEDs indicate the current diagnostic mode. 

●

●

When diagnostic mode is first entered it will be in PC 

temperature sensor mode (2). Use the   and   buttons to 

scroll through the various diagnostic modes (1 – 8).

●

●

To return to normal operation press the   button once.

The following temperature LEDs are illuminated to indicate 

the current diagnostic mode:

1 

Optical Download

2

Provisions compartment (PC) temperature 

sensor

3

Freezer compartment (FC) temperature sensor

4 

Evaporator (EV) temperature sensor

5

Inputs and Outputs display

6

Provisions compartment 2nd (PC2) temperature 

sensor or Ambient temperature sensor (French 

door models only)

7

Ice Tray Temperature sensor

8

Fault History

Optical Download

●

●

This sends encoded data through the Key Lock LED 

indicator at the top of the display.

●

●

A light pen is required to retrieve information from the 

power/control module.

–   Light Pen (425930) & a laptop computer with F&P 

Smart Tool diagnostic program installed.

1

  Enter diagnostic mode.

2

  Scroll to the Optical Download mode by pressing the   

button once.

3

  Place a light pen over the Key Lock LED indicator until 

download is complete.

4

  Return to normal operation by pressing the   button.

Temperature Sensor Indication

In these modes LED indicators and temperature LEDs are 

used to show the temperature reading of sensors. 

The following table shows which LED indicators are used to 

represent the various temperature sensors. 

2 – PC temp 

PC Compartment

3 – FC temp

FC Compartment

4 – EV temp

PC + FC Compartment

6 –  PC2 temp/Ambient 

temp (FD models)

PC compart + Blinking

7 – Ice tray temp

Ice On/Off

The temperature LEDs display the temperature reading in a 

binary code.

1

  Enter diagnostic mode and then scroll to the desired mode 

using the   button.

2

  Add up the binary number indicated by the temperature 

LEDs.

3

  Subtract 40 from the result in order to get the temperature.

4

  Return to normal operation by pressing the   button.

Input / Output display

The Input/Output Status menu displays what devices (eg 

light, PC door, FC door, compressor, etc) are currently 

running or turned on.

In this mode, the state of each peripheral input and output 

is displayed.

FC FAN

DEFROST HTR

COMPRESSOR

To enter the mode, the steps are:

1

  Enter the diagnostic mode.

2

  Scroll to the input/output mode by pressing the   button 

3 times.

3

  The respective LED turns on when a device is running, as 

shown in Fig.1 above.

4

  Return to normal operation by pressing the   button.

Fault History

The fault history will indicate the last fault that occurred 

with the appliance. This will be displayed for a period of 

four days, after which it can only be accessed via optical 

download. 

Fault history is displayed in the same format to normal fault 

code except the LEDs are not flashing.

Press and hold

 

 

,   and   together for 4 seconds then 

close the door(s). The ice tray will flip. Force another cycle. 

The ice tray will flip and spill the water into the ice bin. 

Empty water and replace bin.

Check icemaker sensor continuity.

When servicing products, consider safety and health issues 

and requirements which must be adhered to at all times. 

Specific safety issues are:

1

  Electrical safety.

2

  Electrostatic discharge.

3

  Vapors while brazing.

4

  Reclaiming of refrigerant.

1

  Take care when removing or servicing any electrical 

components to avoid electrical shock or short circuit 

conditions.

2

  Take care when removing plastic components at low 

temperatures as breakages can occur with these 

components.

3

  Extreme heating of plastic components can cause distortion 

of those parts being heated.

4

  Avoid overheating temperature sensitive devices such as the 

element thermal fuses and cabinet sensors.

5

  Avoid using solvents, citrus-based cleaners on all plastic 

parts. We advise only warm soapy water be used.
