Display shows E6 and the compressor does not run or stops shortly after starting.

Safety first: Unplug the ice maker before accessing the compressor compartment. Capacitors can hold a charge; discharge safely if present.

Steps to troubleshoot:

• Access compressor area: Remove the rear service panel to expose the compressor, start relay, and overload protector.
• Listen for symptoms: When briefly powered, a clicking sound every few seconds often indicates a start relay or overload issue. Unplug immediately after testing.
• Inspect start components: Remove the start relay and overload from the compressor terminals. Check for burn marks, melted plastic, or rattling (a sign of a failed PTC relay).
• Test continuity: Use a multimeter to test the overload protector and relay per Haier specs. Replace any component that is open or out of range.
• Check compressor windings: Measure resistance between the compressor terminals (C-R, C-S, R-S). Compare to service data. Very high or zero readings may indicate a failed compressor.
• Reassemble and test: Install new start components if needed, reconnect wiring, and briefly power the unit to see if the compressor starts and runs smoothly.

When to call a technician: If the compressor is locked or windings are out of spec, the sealed system requires professional replacement and refrigerant handling.
