E19 error, compressor starts briefly then shuts off, repeated attempts, possible overcurrent detection.

Safety: Unplug the appliance before testing the compressor. Components can be hot.

• Clean condenser and check fan: Ensure the condenser coil is clean and the condenser fan operates correctly to reduce head pressure.
• Verify start components: Confirm that the correct start relay and overload are installed for the Zanussi compressor model. Replace any mismatched or burnt components.
• Test compressor windings: With power off, remove the start device and measure resistance between compressor terminals. Compare to specifications. Very low resistance or a short to ground indicates a failed compressor.
• Allow cool-down: If the compressor is overheated, allow it to cool fully and retry. Persistent E19 after cool-down suggests mechanical or electrical failure.
• Professional replacement: If the compressor is locked or windings are shorted, the compressor and sealed system must be replaced by a qualified refrigeration technician.
