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. (light emitting diode) returns to FILL...
1. Loose connection somewhere in the main power circuit to the microprocessor controller (computer).
R. Microprocessor controller (computer) L.E.D. (light emitting diode) 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 on page 54.
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. (light emitting diode) 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.
