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" (light
emitting diode [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.
