e. Open main door. The dryer must stop and ALL indicator lights on the back side of the microprocessor
(computer) board must go out. (Refer to the illustration on previous page [page 77].)
f. Try to restart the dryer with the main door open.
g. The microprocessor (computer) board’s L.E.D. (light emitting diode) display must read “DOOR.”
h. Close the main door and restart the dryer.
i. Functional check of microprocessor (computer) board is complete.
2. For Models With Johnson Controls DSI (Direct Spark Ignition) 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 Direct Spark Ignition (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. [light
emitting diode] flashes).
A steady L.E.D. indicator indicates normal operation.
No L.E.D. indicator indicates a power or an internal failure has occurred.
