O. Microprocessor controller (computer) locks up and L.E.D. (light emitting diode) display reads
erroneous message(s) or only partial segments...
1. Transient power voltage spikes...disconnect the electrical power to the dryer, wait one (1) minute
and reestablish power to the dryer. If problem is still evident ...
a. Failed microprocessor controller (computer).
b. Failed keyboard label (touchpad) assembly.
P. Dryer stops during a cycle, microprocessor controller (computer) buzzer (tone) sounds for
5 seconds, and then the L.E.D. display reads dSFL for approximately 30 seconds, and then
returns to FILL...
1. Loose connection somewhere between the microprocessor controller (computer) and the
microprocessor temperature sensor.
2. Loose "dSFL" 1/8-amp fuse on the microprocessor controller (computer).
Q. Dryer stops during a cycle, microprocessor controller (computer) buzzer (tone) sounds for
5 seconds, and then the 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 tumbler (basket) rotation or circuit ...
a. Tumbler (basket) not rotating ...
1) Broken or loose V-belts.
2) Failure in drive motor circuit...refer to
Section B
,
Section C
, and
Section D

.
b. Failed rotational sensor.
c. Broken wire or connection between rotation sensor and microprocessor controller (computer).
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.
Hot
display will not clear until temperature sensed has dropped to 220° F or lower and the
micro-processor controller (computer) is manually reset by pressing the
CLEAR/STOP
key.
