To Test the Fresh Food Compartment Lights

Enter the service test mode and go to test number 3
to turn on the lights or test number 23 to test the door
switch. This is the Fresh Food compartment light test
and "FD" is displayed in the freezer temperature
display.
Open the Fresh Food compartment doors one at a time,
a 1, 2 or a 3 will be displayed in the Fresh Food
compartment temperature display.
A (1) in the Fresh Food compartment temperature
display means the lower control board is sending a
signal to the lighting control board, telling the lighting
control to turn on the food compartment lights in lighting
zones 1 and 2. A (2) in the Fresh Food compartment
temperature display means there is no signal going
from the lower control board to the lighting control.
Remove both the lighting control board and the lower
control board. Check for bad connections on the
jumper harness running between the two boards. If the
connections are good, replace the lower control board.
