Possible reasons for overheating ...
1. Restriction in location exhaust duct work ...
a. Dryer exhaust damper stuck in closed position.
b. Undersized exhaust duct work
2. Insufficient make-up air.
K. Microprocessor controller (computer) LED display read “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 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 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 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 LED display will read “SEFL”. The LED 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).
4. Failure in the rotational sensor circuit ...
a. Failed rotational sensor.
b. Loose connection or break between the rotation sensor and the microprocessor controller (computer).
L. Microprocessor controller (computer) will not accept any, or only accept certain keyboard
(touchpad) entries...
1. Failed keyboard (touchpad) label assembly.
M. Microprocessor controller (computer) locks up and the LED display reads erroneous message(s)
or only partial segments...
1. Transient power voltage (spikes)...disconnect power to the dryer, wait one (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 Items M2 through M4.
2. Failed keyboard (touchpad) label assembly.
