e. Open main door. The dryer must stop and ALL output indicator lights on the back side of the
microprocessor controller (computer) board must go out. (Refer to the illustration on previous
page.)
f. Try to restart the dryer with the main door open.
g. The microprocessor controller (computer) board’s light emitting diode (L.E.D.) display must read
“DOOR.”
h. Close the main door and restart the dryer.
i. Functional check of microprocessor controller (computer) board is complete.
2. For Models With Hot Surface Ignition (HSI) Module (CE Version)
a. Upon completing installation of the replacement
HSI module, reestablish power to the dryer.
b. The HSI module’s “red” indicator light will light
for up to approximately 5-seconds (self check
routine). If the HSI module’s “red” indicator
light stays on or flashes continuously, then the
HSI module is wired incorrectly or has failed.
c. Start the drying cycle.
d. The Hot Surface Ignitor will turn on, and a
After approximately 4-seconds the glo-bar will
shutoff and the gas valve will be energized.
Ignition (flame) should now be established.
e. With the burner flame on, remove the flame sensor wire from the S2 terminal of the HSI module. The
burner flame must shut off immediately.
f. Stop the drying cycle, with the flame sensor wire still removed, restart the drying cycle.
g. The Hot Surface Ignitor will turn on, and after a few seconds later the gas valve will be energized and the
Hot Surface Ignitor will shut off. Ignition (flame) should be evident for approximately 7-seconds and
then shut off.
h. The HSI module will attempt to light burner only “once.” If flame is not reestablished the HSI module
will lockout and the “red” indicator light will flash continuously.
i. Functional check of the HSI module is complete.
1) Replace the flame sensor wire from the S2 terminal to the HSI module.
