Refer to the Service Diagnostic Tests and run the Console Switches and Indicator
Test routine.
Start the test by pressing the Start button.
1.
No LEDs light up
a) Visually check that connectors P3 and P4 are inserted all the way into the control board.
b) If these connections are good, remove P3 and P4 from the control board while the
power is still on. Check the DC supply voltage to the indicator and switch assembly by
measuring the voltage between P3-4 (black lead of meter) and the following points:
•
P3-10
•
P3-11
•
P3-12
•
P3-13
•
P3-14
•
P4-2
•
P4-3
A voltage of at least 3 VDC should be measured at all of these points. If not, replace the
control board.
c) If at least 3 VDC is measured, replace the key switch/console assembly.
2.
A group of LEDs do not light up

all of the LEDs in the group will be disabled.
b) Replace the key switch/console assembly.
3.
A single LED is OFF
