Preparing for Vacation
For long vacations or absences, remove food and unplug the
refrigerator. Move the fresh food control to the OFF position, and
clean the interior with a baking soda solution of one tablespoon
(15 ml) of baking soda to one quart (1 L) of water. Leave the
doors open.
Move the icemaker feeler arm to STOP (up) position and shut
off the water supply to the refrigerator.
If the temperature can drop below freezing, have a qualified
servicer drain the water supply system to prevent serious property
damage due to flooding.
Preparing to Move
Secure all loose items such as grille, shelves and drawers by taping
them securely in place to prevent damage.
Be sure the refrigerator stays in an upright position during moving.
