If the dryer repeatedly has DSI module “LOCKOUT” failures, the cause may be due to high voltage not getting into the DSI module ignitor probe assembly.

5)Check to insure that the red high voltage wire (between the ignitor spark electrode and the DSI module) is not wrapped around the sensor probe wire (the wire between the DSI module FP terminal and the Ignitor/Flame-Probe Assembly). If the wires are touching one another, separated and secure in place AWAY FROM ONE ANOTHER.

6)Check to insure that the dryer is properly grounded and that the ground connections (GND) to the DSI module are secure.

7)If the problem persists, it is most likely to be in the external components (not the DSI module), or wiring, due to a “FLAME-OUT”...proceed as follows:

NOTE: Preliminary steps - DO NOT OMIT - to minimize the time required to troubleshoot this system.

a)Disconnect the electrical power to the dryer.

b)Visually check the DSI module components for visual damage.

c)Check wiring for loose connections, nicks, or cracking at the ceramic insulator, or shorting of the sensor to the burner.

d)Inspect the DSI Ignitor/Flame-Probe Assembly...

...check electrode for visible cracking at the ceramic insulator or shorting of sensor to burner

...check to insure that the flame sensor rod is positioned over the flame area

...check for carbon deposits on the flame sensor rod

...check to insure that there is a 1/8” (3.175 mm) +/- 1/32” (+/- 0.79248 mm) gap between the ground rod and the ignitor spark electrode

b.After performing these inspections and making corrections - if any - restore power to the dryer...start the dryer and operate through one (1) complete cycle to insure that ALL components are functioning properly. If a no heat condition persists refer to the Troubleshooting Flow Charts on page 27, page 28, and page 29.

1)To effectively use this information or the flow charts, each step must be completed in sequence, performing whatever test are suggested. After the completion of each test, the guide will direct the Service Technician to the next logical step in the troubleshoot sequence based on the outcome of the previous check.

2)Components should be replaced only after each step has been completed and replacements after each step has been completed and replacement is suggested in the flow chart. However, the experienced technician realizes that a loose connection or broken or shorted wire may be at fault where electrical components are concerned...and not necessarily the suspected component itself.
