a. Upon completing installation of the replacement HSI module, reestablish power to the dryer.
b. The HSI modules red indicator light will
light for up to approximately 5-seconds (self
check routine). If the HSI modules 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.
i. Functional check of the HSI module is complete.
1) Replace the flame sensor wire from the S2 terminal to the HSI module.
