For Direct Spark Ignition (DSI) System Models Manufactured With ADC Module Part No. 880815
a. Upon completing installation of the
replacement Direct Spark Ignition (DSI)
module, reestablish power to the dryer.
b. Start the drying cycle.
c. The ignition (DSI) modules L.E.D. (light
emitting diode) indicator will be off for up
to approximately 1.5-seconds (prepurge
time).
d. The modules indicator light will then turn
green. The gas valve will be energized
and the ignitor probe will spark for
approximately 8-seconds. The burner flame
should now be established. If the L.E.D.
on the module lights green continuously,
then the system is functioning properly. A
flashing green L.E.D. (lockout mode)
indicates that ignition flame
has not been
confirmed.
e. With the burner flame on, remove the flame
sensor wire from the sense terminal of the
DSI module.
f. The burner flame must shut off and the ignition module must lockout with the DSI modules indicator
light flashing green.
g Stop the drying cycle, with the flame sensor wire still removed, restart the drying cycle.
h. The ignition module must proceed through the prepurge, with the indicator light off, the ignition trial
time of approximately 8-seconds, with the indicator light green, and then proceed to lockout with the
indicator light flashing green.
i. Functional check of the Direct Spark Ignition (DSI) Module is complete.
1) Replace the flame sensor wire from the FS terminal to the DSI module.
