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

a.DSI (Direct Spark Ignition) MODULE "RED" L.E.D. (Light Emitting Diode) INDICATOR LIGHT

This "red" L.E.D. (light emitting diode) light is located in the upper right corner of the DSI (Direct Spark Ignition) module (refer to the top illustration on page 30). This is a diagnostic indicator that simplifies the operational and troubleshooting procedures of the DSI system.

b.LOCK-OUT MODE - DSI (Direct Spark Ignition) module "red" L.E.D. (light emitting diode) indicator light stays on continuously. This indicates there is a system fault and most likely the fault is the DSI module itself.

c.FLAME-OUT - burner flame shut down by the DSI (Direct Spark Ignition) module due to lack of flame verification. This condition occurs only after ignition is evident but is lost. The DSI system will immediately attempt to relight the burner.

d.RECYCLE - flame has been sensed but lost. Initiate a new sequence (THERE ARE NO RETRIES).

2.Troubleshooting and System Basic Diagnosis

a.Preliminary Steps

The following steps must be preformed to minimize the time required to isolate cause of fault.

1)DSI (Direct Spark Ignition) module L.E.D. (light emitting diode) indicator light is off (no "red" or "green" light).

a) Check for voltage (approximately 24 VAC) across the

DSI model terminals "TH" and "GND...

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

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

2)DSI (Direct Spark Ignition) module L.E.D. (light emitting diode) indicator lights "red" for approximately 1.5 seconds (prepurge). This indicates that ALL the controls (including ALL the safety circuits) are functioning and power is being supplied to the DSI module.

3)DSI (Direct Spark Ignition) module L.E.D. (light emitting diode) indicator lights "green." This indicates a normal heating cycle. This also indicates that the preliminary diagnostics of the module has confirmed that the DSI module is functional.

4)DSI (Direct Spark Ignition) module L.E.D. (light emitting diode) indicator lights "red" continuously...

LOCK-OUT MODE. This indicates that there is a system fault and most likely the fault is internal to the DSI module. To make sure, open and close the main door. Restart the dryer...if the module LOCKS-OUT ("red" L.E.D. indicator light stay on continuously) again, replace the DSI module.
