CLEANING Before cleaning the oven, unplug the power supply cord of the oven. If impossible, open the oven door to prevent an accidental oven start. INSIDE OF THE OVEN Use a damp cloth to wipe out crumbs and spillovers. It is important to keep the area between door and cavity front clean to assure a tight seal. Remove greasy spatters with a sudsy cloth, then rinse and dry. Do not use harsh detergent or abrasive cleaners. GLASS TRAY The glass tray can be washed by hand or in dishwasher. CONTROL PANEL Wipe with a damp cloth followed immediately by a dry cloth. DOOR If steam accumulates inside or around the outside of the oven door, wipe the panel with a soft cloth. This may occur when the microwave oven is operated under high humidity conditions and in no way indicates a malfunction of the unit. OUTSIDE OVEN SURFACE Clean with damp cloth.
