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.
