Haier ice maker shows E5 and does not harvest ice properly; ice may freeze to the evaporator.

Safety first: Unplug the ice maker before accessing the evaporator or heater. Avoid contact with sharp metal edges.

Steps to diagnose:

• Access evaporator assembly: Remove the front or top cover to expose the ice-making area. Locate the harvest heater (often a small heater bar or wire under or around the evaporator plate or ice tray).
• Inspect visually: Look for burnt spots, broken heater elements, or disconnected wires.
• Test heater continuity: Disconnect the heater leads and measure resistance with a multimeter. An open circuit (OL) indicates a failed heater that must be replaced.
• Check wiring and connectors: Ensure all heater wiring is intact and firmly connected to the main control board or relay block.
• Control board check: If the heater tests good, the control board may not be energizing it. Look for burnt relay contacts or board damage. Board replacement may be required.
• Reassemble and test: After replacing any faulty parts, reassemble panels, restore power, and run a full ice cycle to confirm proper harvest.

When to call a technician: Harvest heater and control board work can be complex; if you are unsure, contact a professional.
