DIAGNOSTIC: Displaying Inlet Air Flow
(Electric Models Only)

Used to display the air flow value at the inlet of the
heater box being measured by the machine
control.

After entering the Diagnostic Test Mode, waiting
for the 5 second delay, and cycling through any
saved fault codes, press the Wrinkle Shield button
to activate air flow detection. A 30 or 50 second
countdown timer will start and the dryer will
turn on.

If the dryer is cold, the countdown will start at
50 seconds.

NOTE:

If the dryer is extremely cold (less than

40°F [4.4°C]) the air flow may not be detected
properly, and “--” will be displayed.

If the dryer is hot, the countdown timer will
start at 30 seconds (cool down period)
followed by an additional 50 second
countdown.

A Dryness Level modifier LED will also be
illuminated to indicate the air flow range
corresponding to the number displayed.

The More LED will be illuminated for air flow
readings above 40 cfm.

The Normal LED will be illuminated for air flow
readings between 29 and 40 cfm.

The Less LED will be illuminated for air flow
readings less than 29 cfm.

If air flow value is low (Less LED is lit),
check to make sure the lint screen is clean,
the door seal is in place and the vent is not
obstructed.

DIAGNOSTIC: Displaying Line Voltage

Used to display the line voltage currently being
measured by the machine control:

After entering the Diagnostic Test Mode, waiting
for the 5 second delay, and cycling through any
saved fault codes, press the Cycle Signal button.
The voltage value will be displayed.

If the line voltage is not seen on L2, the display
will flash

L2
