Electronic control problem

Controlling the Freezer temperature
The freezer temperature can be set between -14°C (8°F) and -25?C (-14°F) to suit your particular needs. Press the freezer button repeatedly until the desired temperature is shown in the temperature display. Keep in mind that foods like ice cream may melt at -16?C (4°F). The temperature display will move sequentially from -14°C (8°F) and -25?C (-14°F). When the display reaches -14?C (8°F), it will begin again at -25?C (-14°F). Five seconds after the new temperature is set the display will again show the actual current
freezer temperature. However, this number will change as the Freezer adjusts to the new temperature. The top and bottom guards in the freezer of this model are the two star sections, so the
temperature in two star sections are slightly higher than other freezer compartment.

Controlling the Fridge temperature
The refrigerator temperature can be set between 7?C (45°F) and 1?C (34°F) to suit your particular needs. Press the fridge button repeatedly until the desired temperature is shown in the
temperature display. The temperature control process for the Fridge works just like the Freezer process. Press the fridge button to set your desired temperature. After a few seconds, the Fridge will
begin tracking towards the newly set temperature. This will be reflected in the digital display. The temperature of the freezer or the refrigerator may rise from opening the doors too frequently, or if a large amount of warm or hot food is placed in either side. This may cause the digital display to blink. Once the freezer and refrigerator return to their normal set temperatures the blinking will stop.
If the blinking continues, you may need to "reset" the refrigerator. Try unplugging the appliance, wait about 10 minutes and then plug back in.

The refrigerator does not work at all or it does not chill sufficiently.
• Check that the power plug is properly connected.
• Is the temperature control on the display panel set to the correct
temperature? Try setting it to a lower temperature.
• Is the refrigerator in direct sunlight or located too near a heat source?
• Is the back of the refrigerator too close to the wall and therefore keeping air from circulating?

E5 on Freezer Display Ambient temperature sensor error Unplug the refrigerator and check the wiring connections in the ambient temperature sensor circuit. If the wiring connections are okay, replace the ambient temperature sensor. If the problem persists, replace the electronic control board. Ambient temperature sensor, Electronic control board

Error codes are brand (and often model) specific. "de" likely indicates something in the defrost process, especially on G.E. Check for ice build-up in the freezer cooling coil. The control board would be suspect, but must be checked to confirm the precise fault.

French Door: Why Does The Control Panel Display "OF OF" Instead Of The Temperature? If the control panel displays "OF OF" instead of the temperature, the refrigerator is in "Cooling Off" mode. In Cooling Off mode, the refrigerator appears to be running normally, but the compressor is off so the unit does not cool. Cooling Off mode is used by retailers to save energy when the refrigerator is on the showroom floor.
Note: Cooling Off mode is also called Demo mode or Exhibition mode.

Disable Cooling Off mode by performing the following:

• Left Door: Simultaneously press and hold the top two buttons on the left side of the display panel until you hear a distinctively different chime sound when the display changes. This will either be a combination of "Energy Saver" and "Freezer", or "Energy Saver" and "Power Freeze/Freezer."

Why Does The Control Panel Display OF OF Instead Of The Temperature...

Teresa, The fridge is in a retailers demo mode and here is what you do to reset it to normal operation:
Left Door: Simultaneously press and hold the top two buttons on the left side of the display panel until you hear a distinctively different chime sound when the display changes. This will either be a combination of "Energy Saver" and "Freezer", or "Energy Saver" and "Power Freeze/Freezer."

• At the top of the door frame: Simultaneously press and hold the "Power Freeze" and "Freezer" buttons until you hear a distinctively different chime sound and the temperatures for the fridge and freezer are both displayed.
• Note: If the temperature is displayed, but then "OF OF" reappears a few seconds later, Cooling Off mode was not disabled. Repeat the actions above, and be sure to press and hold the buttons at the exact same time until the distinctive chime sound is heard and both temperatures are displayed.

The control board of your refrigerator and freezer must be check and replace if found to be defective.
You already did the remedy with a short success and trouble is back again. As you know the control board has a micro-controller on its electronic board.
To be able to function it well, the temperature control and thermostat must be good, including the system refrigerant must be on the right charge of freon. Once all of that is functioning well, the problem is really on electronic control board.
Thanks for asking.

Self Diagnostics
To enter Self Diagnostic mode, both temperature control panel displays must be illuminated. A display
can be illuminated by pressing an adjacent temperature adjustment button. When both displays are
illuminated, set the freezer and refrigerator temperature settings to 5. Simultaneously press and hold all
4 temperature adjustment buttons for approximately 3 seconds. A flashing 0 in the refrigerator and
freezer displays will indicate that the refrigerator is in Self Diagnostic mode.

For temperature control panels with single-digit displays, the COLDER temperature adjustment button
will increment the numbers up and the WARMER temperature adjustment button will increment the
numbers down. Use the freezer temperature adjustment buttons to enter the test code number in the
freezer display. Use the refrigerator temperature adjustment buttons to enter the test code number in
the refrigerator display. When a test code has been entered, the displays will flash to confirm the test.
Press the HOLD button for 3 seconds to begin the test.
For temperature control panels with 3-digit displays, the COLDER temperature adjustment button will
increment the numbers down and the WARMER temperature adjustment button will increment the
numbers up. Use the freezer temperature adjustment buttons to enter the test code number in the
freezer display. Use the refrigerator temperature adjustment buttons to enter the test code number in the refrigerator display. When a test code has been entered, the displays will flash to confirm the test
code. Press any button other than a temperature adjust button to begin the test.
When testing has been completed, do one of the following things:
• Enter code 1 5 to completely reset the system.
• Enter code 1 6 to exit diagnostic mode. GSS manual
