IndicatorsNOTE 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., dryers 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 B.
