American Dryer Corp ADG-60 service manual DMC computer L.E.D. display reads Hot

Page 34

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

a.Loose wire or termination in sensor harness somewhere between the sensor bracket and the Dual Microprocessor Control (DMC) computer.

b.Failed Dual Microprocessor Control (DMC) computer temperature sensor.

I. DMC computer L.E.D. display reads "Hot"

The "Hot" display condition indicates a possible overheating condition. The Dual Microprocessor Control (DMC) computer monitors the temperature in the dryer at all times. If the DMC computer detects that the temperature in the dryer has exceeded 170° F (77° C), it will disable ALL of the dryer outputs (shut the dryer down), the buzzer (tone) will sound for approximately 5 seconds, and the L.E.D. display will continue to read "Hot" until the temperature has dropped to 170° F (77° C) or lower and the DMC computer is manually reset by closing and opening the Program Switch (PS).

Possible reasons for overheating

1.Restriction in location exhaust duct work.

a.Dryer exhaust damper stuck in closed position.

b.Undersized exhaust duct work.

2.Insufficient makeup air.

J.DMC computer L.E.D. display reads "SEFL"

The "SEFL" display condition indicates a rotational sensor circuit failure which means there is a fault somewhere in the basket (tumbler) rotation detection circuit or the Dual Microprocessor Control (DMC) computer program related to this circuit (PL01) is set incorrectly in the active mode (SEn) with the optional rotation sensor and should be set in the nonactive mode ("nSEn").

If the dryer is equipped with the optional rotational sensor and for whatever reason the Dual Microprocessor Control (DMC) computer detects that the basket (tumbler) is not turning, it will disable ALL of the dryer outputs (shut the dryer down) and the L.E.D. will read "SEFL". The L.E.D. display will continue to read "SEFL" until the Dual Microprocessor Control (DMC) computer is manually reset by closing and opening the Program Switch (PS).

Possible causes

1.Loose or slipping (out of proper adjustment) basket or tumbler belt.

2.Broken basket or tumbler belt.

3.Failed motor.

4.Failure in the rotational sensor circuit

a.Failed rotational sensor.

b.Loose connection or break between the rotation sensor and the Dual Microprocessor Control (DMC) computer.

K.DMC computer will only accept certain keyboard (touchpad) entries

1.Failed Keyboard (touchpad) label assembly.

2.Failed Dual Control (DMC) computer.
