TROUBLESHOOTING GCCO-C CONT’D

PROBABLE CAUSE

CORRECTIVE ACTION

Defective control transformer
(12 VAC).

Check transformer for normal operation.

Check primary coil for 120 VAC and 154.1

Ω

. Check secondary coil

for no less than 10.5 VAC and 1

Ω

If voltage is measured on primary:

Check for voltage on secondary.

Replace transformer.

If voltage is not measured on primary:

Check wires for any shorts.

Defective rectifier

Check for no less than 10.5 VAC on

TP1

and 5 VDC on

TP2

If correct voltage is present at

TP1

and present, but low at

TP2

unplug both ribbon connections from CPU and re-measure at

TP2

If voltage remains low at

TP2

replace CPU (40102-311).

If voltage at

TP2

increased to 5 VDC when ribbon was unplugged,

plug ribbon back in to CPU and disconnect from Interface board.

Re-measure at

TP2

If voltage dropped to below 5 VDC replace ribbon cable (31110-01).

If voltage remains at 5 VDC, plug ribbon back into Interface board
and measure for 5 VDC at

TP3.

If voltage is present at

TP3

and display is still not on, press and hold

the

R/C

button on board if LED’s come on replace Interface board.

If LED segment does not illuminate or the LED is blank, replace
LED.

Note: Display should now be operating.
