Refrigerator display shows E6 and the compressor does not start or runs erratically.

Safety: Unplug the refrigerator. Work only on de-energized circuits. Compressor and inverter circuits carry dangerous voltages.

• Access rear electronics: Move the refrigerator away from the wall and remove the lower rear cover to expose the compressor and inverter module.
• Inspect wiring: Check the multi-pin connector between the main control board and the inverter module. Look for loose plugs, burnt pins, or damaged cables.
• Reseat connectors: Firmly unplug and re-plug the harnesses to ensure good contact.
• Check for visible damage: Examine the inverter module (mounted on or near the compressor) for burn marks, cracked casing, or melted areas. If present, the inverter must be replaced.
• Power reset: After reseating connectors, restore power and observe if the compressor starts and E6 clears.
• Professional service: If E6 persists or the compressor does not run, the inverter or main control board likely needs replacement. This should be done by a qualified technician due to high-voltage and refrigerant system proximity.
