The DC switches provide "door open" information
to the power control board (PCB).
Note: The fans turn off when the doors are
opened (DC door switches control operation)
and delay 10 seconds before restarting when the
doors are closed again. The freezer door switch
controls only the freezer fan. The fresh food door
switch controls both the fresh food and freezer
fan operation.

Interior Lights

Both the fresh food and freezer interior lights use
120 VAC, 40-watt incandescent bulbs. There are
4 bulbs (160 watts) in the fresh food section, and
2 bulbs (80 watts) in the freezer section.
Freezer bulb voltage is checked at CN07 on the
terminal block. Test for voltage between pin #9
and pin #10.
Note: Pin #10 is only at neutral when the freezer
door AC switch has closed contacts (door open).
Fresh food bulb voltage is checked at CN09 on
the terminal block. Test for voltage between pin
#4 (neutral) and pin #3.
Note: Pin #3 is only at line voltage (120 VAC)
when the fresh food AC door switch has closed
contacts (door open).
WARNING: The center terminal of the freezer
light socket is energized whenever the refrigerator
is plugged in and the main switch is closed,
regardless of door position.
