DEFROSTING YOUR REFRIGERATOR
Defrosting occurs fully automatically in the refrigerator
compartment during normal operation. The defrosted
water collected by the evaporating tray evaporates
automatically.
NOTE: The evaporating tray and water drain hole (back
of the refrigerator crisper shelf) should be cleaned
periodically to prevent water from collecting on the
bottom of the refrigerator instead of flowing out.
