2.7
Owner's of the ADC Clothes Dryer AD-200 gave it a score of 2.7 out of 5. Here's how the scores stacked up:
36
3) Air Turbulence
If there is sail switch flutter due to air turbulence or improper blower (squirrel cage fan) rotation or
a restriction in the exhaust ductwork, the Direct Spark Ignition (DSI) module will cycle erratically.
This in turn might cause the DSI module to “LOCKOUT” (where the light emitting diode [L.E.D.]
indicator will LIGHT “RED” CONTINUOUSLY).
a) If air turbulence cause the flame to move away from the flame-probe electrode (of the Ignitor/
Flame-Probe Assembly), or if the flame goes out completely during the heat (flame) cycle, the
DSI module will attempt to reestablish a flame by going into a re-ignition cycle.
4) DSI Module
If there is some sort of operational interference in the DSI system, the DSI module (acting as the
“controller” for the system) will go into a “LOCKOUT” mode (where the L.E.D. indicator will
LIGHT “RED” CONTINUOUSLY).
a) Operational interference is any adverse condition (whether internal or external) to the system.
(Electrical noise is considered external noise interference because it can cause the DSI module
to cycle erratically.)
NOTE: To reset the DSI module if it is in the “LOCKOUT” mode, “Burner Control Fault” will display.
To clear this fault press the “CLEAR/STOP” key.
If the GAP, the ALIGNMENT, and the POSITION of the Ignitor/Flame-Probe Assembly are
correct, if the gas flow and pressure is constant and consistent; if there is no adverse air turbulence;
and if the DSI module remains in the “LOCKOUT” mode (where the L.E.D. indicator will
LIGHT “RED” CONTINUOUSLY) then, there is a malfunction with the DSI module itself, and
it must be replaced.
NOTE: To reset the DSI module if it is in the “LOCKOUT” mode, “Ignitor Control Fault” will display.
To clear this fault press the “CLEAR/STOP” key.
5) Wiring
If the DSI module is in the “LOCKOUT” mode (where the L.E.D. indicator will LIGHT “RED”
CONTINUOUSLY), and the mechanical components have been checked (i.e., the Ignitor/Flame-
Probe Assembly, the gas valve, etc.), then, there may be a problem somewhere in the DSI system
wiring.
a) Check ALL the wiring within the DSI system, especially the ground connections at the DSI
module and the Ignitor/Flame-Probe Assembly.
NOTE: Check for any possible damage to the ceramic insulators on the ignitor electrode and the
flame-probe electrode of the Ignitor/Flame-Probe Assembly.
b) Make sure the flame-probe electrode of the Ignitor/Flame-Probe Assembly is positioned no
more than 1-inch (2.54 cm) maximum from the burner tube.
