Console Diagnostics.

DIAGNOSTIC: Displaying Inlet Air Flow

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

the machine control.

After all saved fault codes have been displayed, 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, 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 all saved fault codes have been displayed, press the Cycle Signal

button. The last 2 digits of the voltage value will be displayed on the dual

7-segment display.

A Dryness Level modifier LED will also be illuminated to indicate the voltage range

corresponding to the number displayed. The Dryness Level LEDs relate to specific

voltage ranges as follows:

■

The More LED will be illuminated for high voltage readings (above 260 VAC).

■

The Normal LED will be illuminated for normal voltage readings (200-260 VAC).

■

The Less LED will be illuminated for low voltage readings (below 200 VAC).

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