GE refrigerator troubleshooting

General Electric (GE) is an American brand of household appliances. The company was founded in the 1878 by the inventor Thomas Edison. In the 1892, it merged with the Thomson-Houston Electric Company, after which it got its modern name. Today, General Electric covers a multitude of industries and activities. The GE has also a unit of the production of household appliances (GE Appliances). The range of products includes refrigerators. Below is a table of the GE refrigerator troubleshooting system.

GE Profile Refrigerator troubleshooting temperature

The temperature display has a self-diagnosis mode that can be accessed and will help the technician to test certain functions of the temperature display, defrost heater, damper, and interior fans. This mode can aid the service technician in quickly identifying failed or improper operation of certain components and systems.

Control diagnostics using the display does not use error codes to identify problems. Instead, the temperature display allows access to components or systems to be checked if a problem is detected.

The temperature display must be in an active mode before entering the self-diagnosis test. If the display is blank, press any temperature button once, then release it. The display will show actual temperatures.

Enter the diagnostic mode by pressing both the freezer temperature (COLDER and WARMER) pads and the refrigerator temperature (COLDER and WARMER) pads simultaneously. All four pads must be held for approximately 3 seconds. Blinking “00”s in both the freezer and refrigerator sections of the display indicate the refrigerator has entered the test mode. Remove fingers within 5 seconds and press any pad to lock-in the test mode. The blinking “00”s will change over to solid (non-blinking) “0”s when the test mode is locked- in. Failure to lock-in the test mode within 30 seconds will time out the test and return the refrigerator to the normal cooling mode.

FZ DisplayFF DisplayModeComments
01Showroom ModeWhen activated, a tone will sound briefly and the display will flash 1 time. The cooling system stops operation. All HMI functions will operate normally.
02Display Combined HMI Software VersionTemperature to main controls communications test. A coded software version is displayed. Dispenser model will show two numbers. See Note 1. Internal display model will test for Pass/Fail. Should show "P". If the format is violated, the display will read "99".
03Display Main Control Software VersionTemperature to dispenser communications test. A coded software version is displayed. Dispenser model will show two numbers. See Note 1. Internal display model will show "F" (no dispenser board). If the format is violated, the display will read "99".
04Combined HMI to Main communicationsDispenser to main controls communications test. Dispenser model will test for Pass/Fail. Should show "P". Internal display will show "F" (no dispenser board).
06HMI Self TestIlluminates all LEDs and numerical segments. FF and FZ displays will initially display "88". Pressing temperature pads will change initial display. Remaining pads pressed will toggle the LED associated with that pad. Filter pad repeatedly pressed will toggle red, green, and amber LEDs. To exit HMI Self Test, press and hold both FF temperature pads simultaneously for 3 seconds, then release.
07Sensor Self TestChecks each thermistor in order and displays "P" for pass, "0" for open circuit, or "S" for shorted circuit.
10Open DamperDamper will open, pause briefly, and then close.
11Fan Speed TestCycles through each fan for 5 seconds.
12100% Run TimeThis mode runs the sealed system 100% of the time. These tests will automatically time out after 1 hour of run time. A refrigerator reset may exit this mode.
13Enter Pre-chillThis places the freezer in pre-chill mode essentially issuing a "Force Prechill" command to the main control. It will return to normal operation on its own. This command will be ignored if the refrigerator is set to OFF/Standby mode.
14Toggle the State of DefrostEach time any button on the temperature board other than four temperature adjust buttons is pressed, the status of the FZ defrost heater will toggle. See Note 3.
15Refrigerator ResetCauses a soft reset to occur at both the Combined HMI and the Main board.
16Test Mode ExitCauses a soft reset to occur at the Combined HMI board. Note: This will not terminate test modes that the main board is maintaining as a result of the service diagnostics mode. To terminate test modes, Refrigerator Reset should be used.
17Degree C/FInternal display model only. Used to set the temperature unit of measure. The current mode is displayed on the FF display ("C" of "F"). Use either of the FF slew keys to adjust the mode. Press any key other than the FF slew keys to set the unit of measure to the displayed selection.
