e.Open main door. The dryer must stop and ALL output indicator lights on the back side of the micro- processor (computer) board must go out.

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

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. indicator will light "red" for up to approximately 1.5 seconds (pre-purge 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 pre-purge, 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.
