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. Start 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 lock out
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.
