SECTION VI

Trouble Shooting

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

ELECTRICAL PARTS SHOULD ALWAYS BE CHECKED FOR FAILURE BEFORE BEING RETURNED TO THE FACTORY.

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

OBSERVE ALL SAFETY PRECAUTIONS DISPLAYED ON THE EQUIPMENT OR SPECIFIED IN THIS MANUAL WHILE MAKING REPAIRS.

A. Phase 5 Coin System Diagnostics

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

Diagnostic (L.E.D. Display) Failure Codes

1. "dOOr" - indicates door switch circuit is open.

a. Keyboard entry was made while main door is open, or

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

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 discontinued and the problem is then corrected.

IMPORTANT: The Phase 5 coin microprocessor controller has its own internal heat sensing circuit fuse protection located on the back side of the controller. If a "dSFL" condition occurs, check to see if this fuse has blown. If it has, DO NOT replace the entire microprocessor controller; replace the fuse and do so with a 1/8-Amp (Slo Blo) fuse ONLY.

NOTE: Once the microprocessor controller detects a problem in the heat circuit, it updates every 30 sec. If the problem was a loose connection in this circuit which corrected itself, the "dSFL" condition would automatically be cancelled.
