E. "dSFL" Display Condition

When the display reads "dSFL" this condition indicates a fault

in the microprocessor controllers heat circuit. This circuit

includes the microprocessor controller, microprocessor

temperature sensor (located in lint compartment) and wires to

and from these two (2) points.

1. Check to see if microprocessor controller has 1/8 amp fuse

on the board, if it does check with out ohm meter. If no

continuity replace with ADC P/N: 136048. If fuse repeatedly

burns out go to step 4.

2. Check for loose connection at the microprocessor sensor

bracket harness connector (located in lint compartment),

and the microprocessor 15 position connector at the

microprocessor controller.

3. Discontinue power to dryer. Disconnect the microprocessor

15 position connector from microprocessor controller and

locate connector holes no. 10 and 15. Disconnect sensor

harness from sensor bracket assembly (located in the lint

compartment). Check for continuity across each wire from

harness connector in lint compartment to appropriate

microprocessor 15 position connector hole (10 and 15).

If no continuity, problem is break in wire or termination.

4. Check for continuity across each microprocessor sensor

wire (microprocessor 15-position connector hole no. 10

and 15) to ground. If continuity is evident, problem is wire

pinched to ground somewhere behind the front panel area.

5. If above procedures check out okay, problem is a defective

microprocessor temperature sensor.
