3. For Direct Spark Ignition (DSI) System Models Manufactured With ADC Module Part No. 880815
a. Upon completing installation of the replacement
DSI module, reestablish power to the dryer.
b. Starting the drying cycle.
c. The ignition DSI module’s light emitting diode
(L.E.D.) indicator will light “red” for up to
approximately 1.5-seconds (prepurge time).
d. The module’s 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.
e. With the burner flame on, remove the flame sensor
wire from the FS terminal of the DSI module.
f. The burner flame must shut off and the ignition
module must lockout with the DSI module’s
indicator light “red.”
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 “red,” the ignition trial time
of approximately 8-seconds, with the indicator light “green,” and then proceed to lockout with the indicator
light “red.”
i. Functional check of the DSI module is complete.
1) Replace the flame sensor wire from the FS terminal to the DSI module.
