1.Direct Spark Ignition (DSI) Troubleshooting Terms (Definitions)

a.LOCKOUT Mode - DSI module “GREEN” light emitting diode (L.E.D.) indicator light blinks continuously. This indicates there is a system fault and most likely the fault is that the DSI module was not able to ignite the gas.

b.FLAMEOUT - Burner flame shutdown by the DSI module due to lack of flame verification. This condition occurs only after ignition has been evident, but, is lost. The system will attempt to relight the burner after 30-seconds.

2.Troubleshooting/System Basic Diagnosis

a.Preliminary Steps - The following steps must be performed to minimize the time required to isolate cause of fault.

1)DSI module L.E.D. indicator is off (no “GREEN” light).

a)Check for voltage (approximately 24 VAC) across the DSI module terminals “THS” and “GND” (ground)...

If voltage (approximately 24 VAC) is evident, then, there is a malfunction within the DSI module itself, and it must be replaced.

b)If there is no voltage, and the problem is not the DSI module or the ignition system, then the problem is elsewhere in the dryer (i.e., dryers’ heat circuit [sail switch, hi-limit circuits, etc.]).
