K. Dual Microprocessor Controller (DMC) computer light emitting diode (L.E.D.) display reads
“SEFL”...
The “SEFL” display condition indicates a rotational sensor circuit failure, which means that there is a fault
somewhere in the basket (tumbler) rotation detection circuit...or...the 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
rotational 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 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. display will read “SEFL.” The
L.E.D. display will continue to read “SEFL” until the DMC computer is manually reset by closing and opening
the Program Switch (PS).
Possible causes...
1. Loose/slipping (out of proper adjustment) basket (tumbler) belt.
2. Broken basket (tumbler) belt.
3. Failed motor.
4. Failure in the rotational sensor circuit...
a. Failed rotational sensor.
b. Loose connection or break between the rotational sensor and the DMC computer.
L. DMC computer will not accept any, or only accept certain keyboard (touch pad) entries...
1. Failed keyboard (touch pad) label assembly.
2. Failed DMC computer.
M. DMC computer locks up and the L.E.D. display reads erroneous message(s) or only partial
segments...
1. Transient power voltage (spikes)...disconnect power to the dryer, wait 1 minute (NOTE: for dryer models
with the optional battery back up...disconnect battery), then reestablish power to the dryer. If problem is
still evident, proceed to Items M2 through M4.
2. Failed keyboard (touch pad) label assembly.
3. Improper grounding of the dryer or the DMC computer ground connections to the panel or the dryer are not
proper.
4. Failed DMC computer.
N. Dryer stops during a cycle and the DMC computer L.E.D. display returns to “FILL”...
If dryer is equipped with optional battery back up...
1. Refer to Item M1, Item M3, or Item M4 above.
