Phase 5 Coin System Diagnostics Trouble ShootingDiagnostic L.E.D. Display Failure Codes SECTIONMicroprocessor Controller Relay Output L.E.D. Indicators L.E.D. Display 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.
