2. "MTR" Output LED Indicator -

If the dryer is started and the motor is not operating, yet both the microprocessor controller display

motor indicator dot and the "dOOr" input LED indicator are on, but the motor output LED indicator is

off, then the fault is in the Phase 5 OPL microprocessor controller itself. If the motor is not operating

and the "MOTOR" output indicator is on, then the problem is elsewhere (i.e., external of the

microprocessor controller).

3. "FWD" Output LED Indicator -

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 display "Forward" indicator dot is on, but the "FWD"

(forward) motor output LED is off; the fault is the Phase 5 OPL microprocessor controller itself.

b. If the drive basket (tumbler) motor is not operating and the "FWD" indicator is on, then the problem

(fault) is elsewhere (i.e., external of the Phase 5 OPL microprocessor controller).

4. "REV" Output LED Indicator -

If the dryer is started and the blower motor is operating but the drive tumbler (basket) motor is not, yet

the Phase 5 OPL microprocessor controller's display "REVERSE" indicator dot is on, but the "REV"

(reverse) motor output LED is off, the fault is the Phase 5 OPL microprocessor controller itself. If the

drive tumbler (basket) motor is not operating and the "REV" (reverse) indicator is on, then the problem

(fault) is elsewhere (i.e., external of the Phase 5 OPL microprocessor controller).
