SECTION VII

TROUBLESHOOTING

The information provided will help isolate the most probable components associated with the difficulty described. The experienced technician realizes that a loose connection or broken or shorted wire may be at fault where electrical components are concerned, however, not necessarily the suspected component itself.

Electrical parts should always be checked for failure before returned to the factory.

The information provided should not be construed as a device for use by an untrained person in making repairs. Only properly licensed technicians should service the equipment.

Observe ALL safety precautions displaced on the equipment or specified in this manual while making repairs.

A. PHASE 5 COIN SYSTEM DIAGNOSIS

ALL major circuits, including door, microprocessor temperature sensor, heat and motor circuits are monitored. The Phase 5 coin microprocessor controller (computer) will inform the user by the light emitting diode (L.E.D.) display of certain failure codes along with indicators both in the L.E.D. display at the outputs of each relay and door switch circuit to easily identify failures.

DIAGNOSTICS (L.E.D.) DISPLAY FAILURE CODES

1.dOOr” - Indicates door switch circuit is open.

a.Keyboard (touch pad) entry was made while main door is open, or

b.There is a fault in the door switch circuit (external of the microprocessor controller [computer]).

c.Possible blown fuse.

2.dSFL” - Indicates a fault in the microprocessor temperature sensor circuit. If a fault is detected in the microprocessor heat sensor circuit, the display will read “dSFL” and the tone (buzzer) will sound for approximately 5-seconds every 30-seconds until...

a.The problem is corrected, or

b.Power to the dryer is disconnected and the problem is then corrected.
