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).

7.“LINT” (LINT DOOR) Input L.E.D. Indicator

a.Should be on ALL the time (unless the lint door is opened then the “LINT” L.E.D. indicator will go out).

b.If the dryer is active (running) and the lint door is opened the “LINT” L.E.D. indicator will go out and the display will read “LINT dOOR.” The dryer will stop until the Lint Drawer has been closed, at which time the L.E.D. display will read “PRESS START.” At this time, to resume the drying cycle press “ENTER/START” key.

8.“MAIN” (MAIN DOOR) Input L.E.D. Indicator

a.Should be on ALL the time (unless the lint door is open or the main door is opened then the “MAIN” L.E.D. indicator will go out).

b.If the dryer is active (running) and the main door is opened the “MAIN” L.E.D. indicator will go out and the display will read “MAIN dOOR.” The dryer will stop until the main door has been closed, at which time the L.E.D. display will read “PRESS START.” At this time, to resume the drying cycle press “ENTER/START” key.

9.“DRUM” (TUMBLER [BASKET] HI-LIMIT) Input L.E.D. Indicator

a.Should be on at ALL times (unless the tumbler [basket] hi-limit switch opens prior during the cycle while the heat was on the display would read “dRUM SAFETY FAIL”). The machine will run with no heat for three (3) minutes or until the temperature drops below 100º F (38º C). Then the machine will shut down still displaying “dRUM SAFETY FAIL” with an audio indication.

10.“SAIL” (SAIL SWITCH) Input L.E.D. Indicator

a.This routine will prevent start up on the machine unless the sail switch is in the correct position. If the sail switch is in the closed position prior to start, the “SAIL” output L.E.D. indicator will be off, the machine will not start and the display will read “SAIL SWITCH FAIL” along with an audio indication.

b.If the sail switch opens during the cycle the “SAIL” output L.E.D. will go out and the display will read “NO AIRFLOW.” The machine will run with no heat for three (3) minutes or until the temperature drops below 100º F (38º C). Then the machine will shut down still displaying “NO AIRFLOW” along with an audio indication.

11.“BURN” (BURN HI-LIMIT) Input L.E.D. Indicator

a.This routine monitors the temperature of the burner. If the burner hi-limit opens during the cycle while the heat was on the “BURN” output L.E.D. indicator goes out and the display reads “bURNER SAFETY FAIL.” The machine will run with no heat for three (3) minutes or until the temperature drops below 100º F (38º C) then the machine will shut down still displaying “bURNER SAFETY FAIL” with an audio indication.
