2. For Models With Hot Surface Ignition (HSI) Module (CE Version)

a. Upon completing installation of the

replacement HSI module, reestablish power
to the dryer.

b. The HSI module’s “red” indicator light will

light for up to approximately 5-seconds (self
check routine). If the HSI module’s “red”
indicator light stays on or flashes
continuously, then the HSI module is wired
incorrectly or has failed.

c. Start the drying cycle.

d. The HSI will turn on, and after

approximately 4-seconds the ignitor will shut
off and the gas valve will be energized.
Ignition (flame) should now be established.

e. With the burner flame on, remove the flame sensor wire from the S2 terminal of the HSI module. The

burner flame must shut off immediately.

f. Stop the drying cycle, with the flame sensor wire still removed, restart the drying cycle.

g. The HSI will turn on, and after a few seconds later the gas valve will be energized and the HSI will shut

off. Ignition (flame) should be evident for approximately 7-seconds and then shut off.

h. The HSI module will attempt to light burner only “once.” If flame is not reestablished the HSI module

will lockout and the “red” indicator light will flash continuously.

Functional check of the HSI module is complete.

1) Replace the flame sensor wire from the S2 terminal to the HSI module.
