PROCEDURE FOR FUNCTIONAL CHECK

OF REPLACEMENT COMPONENTS

1.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.
