Modern GE refrigerators come equipped with intelligent self-diagnostic systems that display error codes when problems arise.
These codes are your first line of defense when troubleshooting issues, helping you identify specific problems and take appropriate action.
Understanding these codes can save you time, money, and the frustration of a malfunctioning refrigerator.
How Self-Diagnostic Codes Work
When your GE refrigerator detects an issue, it activates its self-diagnostic feature and displays an error code on the control panel. Each code corresponds to a specific problem within the refrigerator’s system. Here’s how the process works:
Error Detection: The system continuously monitors various components and functions.
Code Generation: When a problem is detected, the system generates and displays a specific error code.
Diagnostic Mode: You can access additional diagnostic information by entering the refrigerator’s diagnostic mode (typically by pressing specific button combinations as outlined in your user manual).
Targeted Troubleshooting: With the error code identified, you can perform targeted troubleshooting rather than guessing at the problem.
Common GE Refrigerator Error Codes: Causes and Solutions

E3: Defrost System Fault
What it means: Problems with the system that prevents ice buildup
Potential impact: Excessive frost, cooling issues, water leakage
Common causes: Defective defrost heater, thermostat, or timer
How to solve: Inspect the defrost heater for visible damage. Use a multimeter to test the defrost heater for continuity.
Check the defrost thermostat for proper operation. Verify the defrost timer is advancing correctly. Replace any faulty components identified during testing.
If frost buildup continues after component replacement, consider a control board issue.
E4: Damper Control Assembly Problem
What it means: Issues with the component that regulates airflow between compartments
Potential impact: Temperature imbalances between freezer and refrigerator sections
Common causes: Stuck damper, motor failure, or control issues
How to solve: Locate the damper control (usually between freezer and refrigerator sections).
Check for physical obstructions preventing proper movement. Verify the damper opens and closes properly when activated.
Test the damper motor for electrical continuity. Replace the damper assembly if the motor fails tests or damper movement is restricted.
E5: Temperature Sensor Fault
What it means: Problems with the sensors that monitor internal temperatures
Potential impact: Improper cooling, fluctuating temperatures
Common causes: Sensor failure, connection issues, or control board problems
How to solve: Locate the temperature sensors in both compartments. Check for secure wiring connections.
Test sensor resistance with a multimeter. Compare readings to manufacturer specifications.
Replace sensors that show incorrect resistance values. Reset the refrigerator by unplugging for one minute.
E6: Ice Maker System Issue
What it means: Problems with the ice production system
Potential impact: No ice production, incomplete ice cycles
Common causes: Water supply issues, motor failure, or sensor problems
How to solve: Verify water supply to the refrigerator is on and filter is not clogged.
Check for frozen water lines and thaw if necessary. Inspect the water inlet valve for proper operation.
Test the ice maker motor for continuity and function. Examine harvest sensors for correct position and operation.
Replace specific ice maker components based on test results. If all components check out, consider replacing the entire ice maker assembly.
E7: Door Switch Malfunction
What it means: Issues with the switch that detects door position
Potential impact: Interior light problems, cooling inefficiency
Common causes: Faulty switch, misalignment, or wiring problems
How to solve: Locate the door switch (usually in the door frame). Check for proper alignment with door closure.
Test the switch with a multimeter for continuity when pressed and released. Inspect wiring connections for damage or looseness.
Clean the switch contacts if they appear dirty. Replace the switch if it fails continuity tests.
E8: Control Board Fault
What it means: Problems with the main electronic control system
Potential impact: Multiple system failures, erratic operation
Common causes: Electronic failure, power surge damage, or software issues
How to solve: Reset the refrigerator by unplugging for at least one minute. Check for visible damage on the control board such as burn marks or swollen capacitors.
Verify proper voltage to the board. Look for loose connections or damaged wires.
If reset doesn’t resolve the issue, professional replacement of the control board is often necessary. Consider using a surge protector to prevent future damage.
