3.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) module’s L.E.D. (light emitting diode) indicator will be “off” 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. 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 module’s 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.
