NoFrost Technology

Automatic defrosting system eliminates manual defrosting.

How it works: A fan circulates cold air while a heating element periodically melts frost on evaporator. Water drains into evaporation tray. Benefits: Consistent temperature, no ice buildup, energy efficient. Maintenance: Ensure drainage holes remain clear; clean evaporation tray annually.

Care & Cleaning

Unplug before cleaning. Never use abrasive cleaners or sharp objects.

Interior: Wipe with solution of warm water and mild detergent. Rinse with clean water and dry thoroughly.
Exterior: Clean with soft cloth and mild detergent. Polish stainless steel surfaces with appropriate cleaner.
Door seals: Clean with warm soapy water; check for proper seal regularly.
Condenser coils: Vacuum dust from rear coils every 6 months for efficiency.
Drain hole: Check and clear if necessary (located at back of freezer compartment).

CAUTION! Never use steam cleaners, hot water, or chemical solvents. Do not scrape ice with sharp objects.
