e. Open main door. The dryer must stop and ALL output indicator lights on the back side of the
microprocessor (computer) board must go out. (Refer to illustration on previous page [
page 57].)
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 (Direct Spark Ignition) module's
L.E.D. (light emitting diode) 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 (Direct
Spark Ignition) module.
f. The burner flame must shut off and the ignition
module must lock out with the DSI (Direct Spark
Ignition) 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
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.
