Q.Dryer stops during a cycle, microprocessor controller (computer) buzzer (tone) sounds for 5-seconds, and then the light emitting diode (L.E.D.) returns to “FILL”...

1.Loose connection somewhere in the main power circuit to the microprocessor controller (computer).

R.Microprocessor controller (computer) L.E.D. display reads “SEFL”...

1.Rotational sensor circuit failure...fault somewhere in the basket (tumbler) rotation or circuit...

a.Basket (tumbler) is not rotating...

1)Broken or loose V-belts.

2)Failure in drive motor circuit...refer to Section B, Section C, and Section D on page 44 and page 45.

b.Failed rotational sensor.

c.Broken wire or connection between rotation sensor and microprocessor controller (computer).

d.Microprocessor controller (computer) is programmed incorrectly for Rotation Sensor Option and dryer is not equipped with this option.

S.Microprocessor controller (computer) L.E.D. display reads “Hot”...

1.Possible overheating condition...microprocessor controller (computer) has sensed a temperature, which has exceeded 220° F (104.5° C).

“Hot” display will not clear until temperature sensor has dropped to 220° F (104.5° C) or lower and the microprocessor controller (computer) is manually reset by pressing the “CLEAR/STOP” key.

T.Heating unit is not operating (no heat)...no voltage at heating unit (i.e., Gas Model - direct spark ignition [DSI] module), when dryer is first started and both the heat indicator dot and the “HEAT” output L.E.D. is on...

GAS MODELS...

1.Fault in sail switch circuit...

a.Sail switch is out of adjustment or has failed.

b.Sail switch damper is not closing or is fluttering...

1)Lint screen is dirty.

2)Restriction in the exhaust ductwork.

3)No exhaust airflow...

a)Failed impellor (fan/blower).

b)Fault in blower (impellor and fan) motor circuit (for Reversing Models ONLY).
