Possible reasons for overheating...
1. Restriction in location exhaust ductwork...
a. Dryer exhaust damper stuck in closed position.
b. Undersized exhaust ductwork.
2. Insufficient make-up air.
J.
Microprocessor controller (computer) will not accept any, or only accept certain keyboard (touch
pad) entries...
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 microprocessor controller (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 inactive mode (“nSEn”).
If the dryer is equipped with the optional rotational sensor and for whatever reason the microprocessor controller
(computer) detects that the basket (tumbler) is not turning, it will disable
ALL
of the dryer outputs (shut the dryer
down), and the light emitting diode (L.E.D.) display will read “SEFL.” The L.E.D. display will continue to read
“SEFL” until the microprocessor controller (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) V-belt.
3. Failed motor (refer to
Item B
and
Item E
on
page 42 and page 43
).
4. Failure in the rotational sensor circuit...
a. Failed rotational sensor.
b. Loose connection or break between the rotational sensor and the microprocessor controller (computer).
K. Microprocessor controller (computer) will not accept any, or only accept certain keyboard (touch
pad) entries...
1. Failed keyboard (touch pad) label assembly.
L.
Microprocessor controller (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 optional battery backup...disconnect battery), then reestablish power to the dryer. If problem is still
evident, proceed to
Item M2 through Item M4
.
2. Failed keyboard (touch pad) label assembly.
