E. “dSFL” DISPLAY CONDITION

When the display reads “dSFL” this condition indicates a fault in the microprocessor controller (computer) heat

circuit. This circuit includes the microprocessor controller (computer), microprocessor temperature sensor

(located in lint compartment) and wires to and from these two (2) points.

1. Check the 1/8-amp fuse on the computer board. If no continuity, replace with ADC PN: 136048. If fuse

repeatedly burns out go to Step #3.

2. Check for loose connection at the microprocessor sensor

bracket harness connector (located in lint compartment),

and the microprocessor 9-position connector at the

microprocessor controller (computer).

3. Discontinue power to dryer. Disconnect the

microprocessor 9-position connector from microprocessor

controller (computer) and locate connector holes 1 and

4. Disconnect sensor harness from sensor bracket

assembly (located in the lint compartment). Check for

continuity across each wire from harness connector in

lint compartment (J11) (pins 1 and 2) to appropriate

microprocessor 9-position connector (1 and 4). If no

continuity, problem is break in wire or bad termination

from that 4-pin (J11) connector through to the computer

9-position connector pins 1 and 4. Also, on the two (2)

wires, check for short to GND.

4. If above procedures check out okay, problem is a defective microprocessor temperature sensor.
