The freezer has two lower LED boards. The
LEDs can be found in the left and right sides of
the cabinet.
Freezer LED Diagnosing
When one of the freezer LED boards fails
completely, the other lower LED board and LED
housing will still work.

NOTE:
When the freezer drawer is opened, the
main board delivers 2 VDC to the LED boards
and increases the voltage to 5 VDC for full
brightness.
The freezer drawer switch is an AC volt switch
that has Normally Closed contacts (N.C.). The
switch is actuated by the drawer front to tell the
main board to turn the freezer LEDs on or off.
Freezer Drawer Switch Diagnosing
When the drawer is opened, the switch contacts
are closed allowing 120 VAC to travel to the main
board. When closed, the drawer front engages
the switch to open the switch contacts, breaking
the 120 VAC circuit to the main board.
Switch Not Pressed (Drawer Open)
J7 on Main Board
• Pin 7 (
red
) to pin 9 (
orange
): 120 VAC
Switch Pressed (Drawer Closed)
J7 on Main Board
• Pin 7 (
red
) to pin 9 (
orange
): 0 VAC
Freezer Drawer Switch Removal
