Freezer shows E8 and may run continuously or not at all; sometimes accompanied by unusual compressor behavior.

Safety: Unplug the freezer before removing rear covers. Inverter boards handle high voltage; do not touch components when powered.

Steps to address E8 (inverter/compressor communication):

• 1. Confirm inverter type: Check your New World model documentation or compressor label. Inverter compressors usually have a separate inverter module mounted near the compressor.
• 2. Inspect wiring: With power disconnected, check the harness between the main control PCB and the inverter board. Ensure all plugs are fully seated and free of corrosion or burn marks.
• 3. Visual check of inverter: Look for obvious damage on the inverter board (burnt components, cracked casing). If present, the inverter is likely faulty.
• 4. Power quality: Ensure the freezer is connected directly to a wall outlet (no long, undersized extension leads) and that supply voltage is stable.
• 5. Replacement: If wiring is intact and E8 persists, replace the inverter board with a compatible New World part. If a new inverter does not resolve the issue, the compressor itself may be defective and will require professional replacement.

Warning: Diagnosis of inverter systems is complex and involves live high‑voltage testing. If you are not trained, contact a qualified refrigeration technician.
