PHASE 5 SYSTEM DIAGNOSTICS

All major circuits, including door, lint door, lint drawer, microprocessor temperature sensor, heat and motor circuits are monitored. The Phase 5 Dual Microprocessor Controller (DMC) computer will inform the user, via the L.E.D. display and at the outputs of each relay (and door switch circuit) to easily identify failures.

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

1."dOOr" - indicates door or lint drawer 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 Phase 5 DMC (computer).

2."dSFL" - indicates a fault in the microprocessor temperature sensor circuit.

a.If a fault is detected in the microprocessor heat sensor circuit, the L.E.D. display will read "dSFL" and the buzzer (tone) will sound for approximately 5 seconds every 30 seconds until

1)power is corrected or

2)power to dryer is discontinued and the problem is then corrected.

IMPORTANT: The Phase 5 DMC (computer) has its own internal heat sensing circuit fuse protection located on the back side of the Phase 5 DMC (computer). If a "dSFL" condition occurs, check to see if this fuse has blown. If it has, do not replace the entire microprocessor controller (computer);

REPLACE ONLY THE FUSE and do so only with a 1/8-Amp (Slo Blo) fuse only.

NOTE: Once the Phase 5 DMC (computer) detects a problem in the heat circuit, it updates, every 30 seconds, so if the problem was a loose connection in this circuit which corrected itself, the "dSFL" condition would automatically be cancelled.

1."SEFL"

a.Indicates a rotational sensor circuit failure meaning that there is a fault somewhere in the basket (tumbler) rotation detection circuit or, the Phase 5 DMC (computer) program related to this circuit (PL01) is set incorrectly in the active mode (SEn) where the dryer is not equipped with the optional rotation sensor and should be set in the inactive mode (nSEn).

NOTE: If the dryer is equipped with the rotational sensor and the display reads "SEFL," reset by closing and opening the Program Switch (PS). Restart the dryer and if the "SEFL" code appears again, investigate further.

4."Hot"

a.Indicates a possible overheating condition. The Phase 5 DMC (computer) monitors the temperature in the dryer at all times. If the Phase 5 DMC (computer) detects that the temperature in the dryer has exceeded 170°F (77°C), it will disable ALL the outputs (shut the dryer down), the tone (buzzer) will sound for approximately 5 seconds and the display will read "Hot". The L.E.D. display will continue to read "Hot" until the temperature sensed has dropped to
