- Wrap foods properly and wipe containers dry to reduce frost build-up.
- Avoid lining storage bins with foil, wax paper, or paper toweling as this interferes with cold air circulation.
- Organize and label food to minimize door openings and search times.
Maintenance Features
Cleaning:
- General: Timely clean dust behind the refrigerator and on the ground to improve cooling and energy efficiency.
- Interior: Turn off power, remove all food, drinks, shelves, and drawers. Use a soft cloth or sponge with two tablespoons of baking soda and a quart of warm water. Rinse with water and wipe clean. Allow to air dry before turning on power.
- Hard-to-reach Areas: Use a soft rag, soft brush, or auxiliary tools (like thin sticks) to clean narrow spaces and corners to prevent contaminant accumulation.
- Door Gasket: Clean regularly with a soft cloth dampened with soapy water or diluted detergent.
- Bottle Frame, Shelves, Drawers: Clean with a soft cloth dampened with soapy water or diluted detergent. Dry with a soft cloth or naturally.
- Exterior: Wipe with a soft cloth dampened with soapy water or detergent, then wipe dry.
- Prohibited Cleaners: Do not use soap, scrub powder, spray cleaner, hard brushes, steel balls, wire brushes, abrasives (e.g., toothpastes), organic solvents (e.g., alcohol, acetone, banana oil), boiling water, acid, or alkaline items, as these can damage surfaces and plastic parts.
- Water Rinse: Do not rinse directly with water or other liquids to avoid short circuits or affecting electrical insulation.
