e. Open main door. The dryer must stop and
ALL
indicator lights on the back side of the microprocessor
controller (computer) board must go out. (Refer to the
illustration
on the previous page.)
f. Try to restart the dryer with the main door open.
g. The microprocessor controller (computer) boards 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 Johnson Controls Direct Spark Ignition (DSI) Module (G760)
Theory Of Operation:
Start the drying cycle. When the gas
burner ignites within the chosen trial for
ignition time (6-seconds), the flame sensor
detects gas burner flame and signals the
DSI module to keep the gas valve
open...as long as there is a call for heat.
The DSI module will LOCKOUT if the
gas burner flame is not sensed at the end
of the trial for ignition period. The trial
for ignition period will be repeated for a
total of three (3) retries/trials (the initial
try and two [2] more retries/trials). If
the flame is not sensed at the end of the
third retry/trial (inter-purge period of 30-
seconds) the DSI module will
LOCKOUT (L.E.D. flashes).
A steady L.E.D. indicator indicates
normal operation
.
No
L.E.D. indicator indicates a power or
an internal failure has occurred.
