Theory of Operation: Start the drying cycle. When the gas
burner ignites within the chosen trial for ignition time
(8-seconds), the flame sensor detects gas burner flame and
signals the DSI module to keep the gas valve open as long as
there is a call for heat. The DSI module will “LOCKOUT” if the
gas burner flame is not sensed at the end of the trial for ignition
period. The trial for ignition period will be repeated for a total
of three retries/trials (the initial try and two more retries/trials).
If the flame is not sensed at the end of the third retry/trial
(inter-purge period of 30-seconds), the DSI module will
“LOCKOUT” (a red L.E.D. diagnostic indicator will flash).
An unlit red L.E.D. diagnostic indicator indicates normal
operation.
A lit green L.E.D. diagnostic indicator indicates dryer controller
is calling for heat and that all interlocks have been satisfied.
Manual Reset Hi-Limit Instructions
!
WARNING
Disconnect power before attempting to reset any
manual hi-limit!
This dryer was manufactured two hi-limit manual reset
thermostats. One is located on the burner and one in the
exhaust. The burner hi-limit thermostat is located in the front
center of the dryer behind the control door. The exhaust
hi-limit is located in the duct above the lint trap.
To reset the burner high limit, disconnect the power, open the
control door and support it with the prop rod. Remove the two
screws that secure the left side of the burner heat deflector.
Swing the heat deflector to the right and out of the way to gain
access to the thermostat. Push the red button in the center to
reset. Replace the heat deflector. Close the control door.
Restore the power.
To reset the exhaust hi-limit, disconnect the power and open
the lint door. Above the lint trap and in the duct below the
tumbler are three sensors. The flat one on the far left is the
hi-limit. Remove the two screws securing the thermostat and
remove it. Push the red button in the center to reset. Replace
the thermostat. Close the lint door. Restore the power.
