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
LOCK-OUT (L.E.D. [light emitting diode]
flashes).
A steady L.E.D. (light emitting diode) indicator
indicates normal operation.
indicates a power or an internal failure has occurred.
