e. Open main door. The dryer must stop processor (computer) board must go out.

and ALL indicator lights on the back side of the micro- (Refer to illustration on previous page [page 113].)

f.Try to restart the dryer with the main door open.

g.The microprocessor (computer) board's L.E.D. display must read "DOOR."

h.Close the main door and restart the dryer.

i.Functional check of microprocessor (computer) board is complete.

2.Direct Spark Ignition (DSI) System

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. 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 lock out 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 Direct Spark Ignition (DSI) Module is complete.

1)Replace the flame sensor wire from the FS terminal to the DSI module.
