Excessive frost buildup in freezer, thick ice on shelves and walls, door difficult to close.

Safety: Unplug the refrigerator before defrosting heavy ice buildup.

• 1. Inspect door gaskets: Look for tears, gaps, or hardened sections. Close the door on a strip of paper; if it pulls out easily, the door gasket may need replacement.
• 2. Check door alignment: Ensure the door is level and closes fully. Adjust hinges if the door sags or rubs.
• 3. Defrost manually: Remove food, unplug the unit, and leave doors open until all ice melts. Use towels to catch water. Do not use sharp tools to chip ice.
• 4. Verify defrost system: After defrosting, monitor for rapid frost return. If frost quickly reappears on the evaporator cover, test the defrost heater, thermostat, and control.
• 5. Usage habits: Minimize door openings and avoid leaving the door open for extended periods, especially in humid environments.
