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.
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
rotation sensor and should be set in the non-active 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) V-belt.
3. Failed motor (refer to Item B on page 37 and page 38 and Item E on page 38).
4. Failure in the rotational sensor circuit ...
a. Failed rotational sensor.
b. Loose connection or break between the rotation 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 a problem
is still evident, proceed to Item M2, Item M3, and Item M4.
