Frost or ice buildup on the back wall or around the evaporator inside the wine cooler.

Safety: Unplug the unit before defrosting or accessing internal components.

Steps to address frost buildup:

• Manual defrost: Turn off and unplug the cooler. Open the door and allow all ice to melt. Place towels to catch water.
• Inspect door gasket: Ensure the door seal is intact and sealing properly to minimize moisture entry.
• Check defrost components: Remove the rear interior panel to access the evaporator, defrost heater, and sensor. Look for broken heater elements or disconnected wires.
• Test heater and sensor: Use a multimeter to check continuity of the defrost heater and defrost sensor/thermostat. Replace any open components with Haier-compatible parts.
• Clear drain: Ensure the defrost drain hole and tube are clear so meltwater can exit properly.
• Reassemble and monitor: After repairs, reassemble and monitor for several days. If frost returns quickly, further diagnosis of the control board may be needed.
