1.“FAN” (BLOWER) Output L.E.D. (light emitting diode) Indicator

A.If the dryer is started and the blower motor is not operating, yet the Phase 6 OPL microprocessor controller (computer) display fan indicator dot and power supply input L.E.D. are on, but the fan output L.E.D. is off, then the fault is the Phase 6 OPL microprocessor controller (computer) itself.

1.If the motor is not operating. The fan indicator dot and output L.E.D. are also on, then the problem (fault) is elsewhere (i.e., external of the Phase 6 OPL microprocessor controller [computer]).

2.“FOR” (FORWARD) Output L.E.D. Indicator (for optional reversing model ONLY)

A.If the dryer is started and the blower motor is operating, but the drive (basket/tumbler) motor is not, yet the Phase 6 OPL microprocessor controller (computer) display “FORWARD” indicator dot is on, the “FOR” (FORWARD) motor output L.E.D. is off; then the fault is the Phase 6 OPL microprocessor controller (computer) itself.

1.If the drive (basket and tumbler) motor is not operating and the forward indicator dot and output L.E.D. in on; then the problem (fault) is elsewhere (i.e., external of the Phase 6 OPL microprocessor controller [computer]).

3.“REV” (REVERSE) 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 and tumbler) motor is not, yet the Phase 6 OPL microprocessor controller (computer) displays “REVERSE” indicator dot is on but the “REV” (REVERSE) motor output L.E.D. is off; then the fault is of the Phase 6 OPL microprocessor controller (computer) itself.

1.If the drive (basket and tumbler) motor is not operating and reverse indicator dot and output L.E.D. is on; then the problem (fault) is elsewhere (i.e., external of the Phase 6 OPL microprocessor controller [computer]).

4.“AIR” (AIR JET) Output L.E.D. Indicator - OPTIONAL

A.“AIR” is on with the display dot at the end of the dry cycle once the display reads “dONE,” it is on for approximately 60 seconds and the output L.E.D. indicator and the display dot go out. If the air jet does not energize it is not the fault of the Phase 6 OPL microprocessor controller (computer). If the output L.E.D. or dot do not go on it is the fault of the Phase 6 OPL microprocessor controller (computer).

5.“HT1” (HEAT) Output L.E.D. Indicator

A.If the dryer is started and there is “No Heat” yet the Phase 6 OPL microprocessor controller (computer) display heat circuit indicator dot is on, but the “HT1” output L.E.D. indicator is off; then the fault is in the Phase 6 OPL microprocessor controller (computer) itself.

1.If the dryer is started and there is “No Heat” yet both the Phase 6 OPL microprocessor controller (computer) display indicator dots and the “HT1” output L.E.D. indicator are on; then the problem (fault) is elsewhere (i.e., external of the Phase 6 OPL microprocessor controller [computer]).

6.“FUSE” (MAIN FUSE) Input L.E.D. Indicator

A.Should be on ALL the time (even if the dryer is not running). If the L.E.D. is not on; then the display will read “CHECK MAIN FUSE.” If the main fuse is good then the fault is on the Phase 6 microprocessor controller (computer).
