NOTE: If the dryer is started (the L.E.D. display indicator dots are on) and there are no outputs

(heat and/or motor output L.E.D.'s are off) and the "dOOr" input L.E.D. is on, the fault is

in the Phase 5 coin microprocessor controller (computer) itself. If the failure was elsewhere

(i.e., dryer's door switch circuit) the L.E.D. display would read "dOOr" if a keyboard entry

was attempted. If the L.E.D. display indicators are on and the door L.E.D. input and

motor/heat output L.E.D.'s are on and the motor and/or heat is not active (ON), then the

problem is not the door switch circuit or the Phase 5 coin microprocessor controller; the

problem is else where in the dryer.

2. "MOTOR" Output L.E.D. 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 L.E.D.

indicator are on, but the motor output L.E.D. indicator is off, then the fault is in the Phase 5

coin microprocessor controller itself. If the motor is not operating and the "MOTOR" output

indicator is on, then the problem is else where (i.e., external of the microprocessor controller).

3. "HEAT" Output L.E.D. Indicator - If the dryer is started and there is no "HEAT," yet the microprocessor

controller display heat circuit indicator dot is on, but the heat output L.E.D. indicator is off,

then the fault is in the Phase 5 coin microprocessor controller (computer) itself. If both the

display heat indicator dot and the heat output L.E.D. indicator are on, then the problem is

elsewhere (i.e., external of the microprocessor controller).
