Display shows E8 and the compressor does not start or cycles rapidly

Safety: Unplug the refrigerator. Work at the rear only when the unit is disconnected. High voltage and hot components are present.

Checks:

• Access compressor area: Remove the rear lower cover to expose the compressor, start device, and control electronics.
• Listen and feel: When previously powered, did the compressor click repeatedly or hum then stop? This often indicates a start device issue.
• Inspect start relay/PTC: Remove the plastic cover on the compressor terminals. Check the start relay/PTC for burn marks or rattling pieces inside when shaken.
• Test compressor windings: With the start device removed and power off, measure resistance between compressor terminals (C-R, C-S, R-S). Values should be finite and not shorted to earth. If windings are open or shorted to ground, the compressor is faulty.
• Replace start device or inverter: If the compressor tests good but the start relay/PTC is suspect, replace it with the correct Zanussi part. For inverter models, a faulty inverter module may need replacement.
• Control board: If the compressor and start components are good but E8 remains, the main PCB may not be sending correct signals and should be diagnosed by a technician.

Warning: Compressor and inverter work involves mains voltage and potentially refrigerant system risks. Non-professionals should not attempt sealed system repairs.
