C. LED Display/Codes

The LED display informs the user of cycle status and program verification and displays important diagnostic and fault codes.

1.Display Operating Status

a.Cycle in Progress - While the dryer is operating, the display will read which cycle is in progress. For example, in the drying cycle (mode), the display will read "dr", and in the cool down cycle (mode), the display will read "CL".

b.Cycle Status - While a cycle is in progress, the display will show the progress of the cycle (load) that is being processed.

1)Automatic Drying Cycle - The cycle status portion of the display will show the percentage of extraction.

2)Timed (Manual) Drying Cycle - The cycle status portion of the display will show the drying or cool down time and will count downward until the programmed time has expired.

c.Alternate Display Programs - Programming allows for the display to read just the cycle in progress or just the basket temperature or to flash back and forth from cycle in progress to basket temperature while the dryer cycle is in progress.

d.Indicator Dots - Located at the top of the display is a series of dots which indicate the various microprocessor controller output functions while a cycle is in progress.

Illus. No. 3 -BLOWER MOTOR INDICATOR - This indicator dot is on whenever a cycle is in progress. In addition, when the anti-wrinkle program is active, this indicator will be on whenever the microprocessor controller is in the guard on time program.

Illus No. 4 - HEAT INDICATOR - This indicator dot is on whenever the microprocessor controller is calling for the heating unit to be active (on).
