3.Troubleshooting/System Detailed Diagnosis

When the dryer calls for heat, 24 VAC from the step down transformer is applied to the “THS” and “GND” (ground) terminals of the Direct Spark Ignition (DSI) module. The DSI module light emitting diode (L.E.D.) indicator will light “GREEN.” The gas valve will be energized, and the spark burst will be evident (on) for approximately 8-seconds at the tip of the electrode/flame-probe assembly. Flame should now be established/ confirmed. If a flame is not sensed/confirmed by the flame-probe sensor after the approximate 8-second spark burst, the DSI module will wait 30-seconds and start ALL over again.

If a flame has been established/confirmed and then lost, the DSI module L.E.D. indicator will continue to light “GREEN,” wait 30-seconds and try again. The flame should now be established/confirmed. If a flame is not sensed/confirmed by the flame sensor probe after the initial try, the module will try two (2) more times then if it is still not established it will go into LOCKOUT.

NOTE: To reset the DSI module if it is in the LOCKOUT mode, open and close the main door, then restart the dryer.

a.System Diagnosis

1)Gas Pressure

A gas pressure test should be taken at the gas valve pressure tap provided on every gas valve to assure that the water column (W.C.) pressure is correct and consistent.

There are two (2) types of devices commonly used to measure water column pressure. They are the spring/mechanical type gauge and the water column test gauge (manometers). The use of the spring/mechanical type of gauges is not recommended because it/they are very easily damaged and they are not always accurate. The preferred type of gauge is the manometer because it is a simple device to use and is highly accurate. A manometer is simply a glass or transparent plastic tube with a scale graduated in inches. When it is filled with water and pressure is applied, the water in the tube rises, showing the exact water column pressure.
