Addendum for Refrigerator Drawers

lighting. Two are located in the center mullion for

of the interior. The LED's are powerd by the LED
power supply located under the unit behind the toe

An internal magnet in the cabinet mates with the

There is also a light switch located on the lower left
side on the rear of the evaporator for the bottom
drawer when opened.
