1) If the motor is not operating and the “MTR” output indicator is on; then the problem (fault) is
elsewhere (i.e., external to the Phase 5 OPL microprocessor controller [computer]).
4. “FWD” Output Light Emitting Diode (L.E.D.) Indicator
(for Optional Reversing Models Only)
a. If the dryer is started and the blower (impellor/fan) motor is operating but the drive (basket [tumbler])
motor is not, yet the Phase 5 OPL microprocessor controller (computer) display “FORWARD” indicator
dot is on, but the “FWD” (forward) motor output L.E.D. is off; then the fault is the Phase 5 OPL
microprocessor controller (computer) itself.
1) If the drive (basket [tumbler]) motor is not operating and the “FWD” indicator is on; then the
problem (fault) is elsewhere (i.e., external to the Phase 5 OPL microprocessor controller [computer]).
5. “REV” Output L.E.D. Indicator
(for Optional Reversing Models Only)
a. If the dryer is started and the blower motor is operating but the drive (basket [tumbler]) motor is not, yet
the Phase 5 OPL microprocessor controller (computer) display “REVERSE” indicator dot is on, but the
“REV” (reverse) motor output L.E.D. is off; then the fault is the Phase 5 OPL microprocessor controller
(computer) itself.
1) If the drive (basket [tumbler]) motor is not operating and the “REV” indicator is on; then the
problem (fault) is elsewhere (i.e., external of the Phase 5 OPL microprocessor controller [computer]).
C. L.E.D. DISPLAY/CODES
The L.E.D. 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 (tumbler) temperature or to flash back and forth from cycle in progress to basket
(tumbler) 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 (computer) output functions while a cycle is in progress.
