For models manufactured 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. (light emitting diode)
indicator indicates normal operation.
No L.E.D. (light emitting diode) indicator
indicates a power or an internal failure has
occurred.
