Display shows E9; ice maker stops; compressor may attempt to start repeatedly with clicking sounds.

Safety: Unplug the ice maker. The compressor and nearby components can be hot; allow them to cool before touching.

Steps to address E9:

• Check power supply: Verify that the outlet voltage matches the Vestfrost rating using a multimeter. Avoid using long, undersized extension cords.
• Access compressor compartment: Remove the rear lower panel to expose the compressor, start relay/PTC, and overload protector.
• Inspect start components: Remove the start relay and overload from the compressor terminals. Shake the relay gently; if it rattles excessively or shows burn marks, it is likely faulty.
• Test continuity: Use a multimeter to check continuity through the overload protector and the PTC relay according to Vestfrost specifications. Replace the compressor start relay/overload assembly if defective.
• Check compressor windings: Measure resistance between the compressor terminals (C, S, R). If any winding is open or shorted to ground, the compressor is likely failed and requires professional replacement.
• Reassemble and test: Install new start components if needed, reconnect wiring, restore power, and observe whether the compressor starts smoothly and E9 clears.

Warning: Refrigerant system and compressor replacement must be performed by a certified refrigeration technician.
