K. Microprocessor controller (computer) L.E.D. display reads “door” and the microprocessor
controller (computer) “DOOR” L.E.D. (light emitting diode) indicator is on...
1. Failed microprocessor controller (computer).
L. Microprocessor controller (computer) will not accept any keyboard [touchpad] entries, (i.e.,
L.E.D. [light emitting diode] display reads "FILL" and when keyboard [touchpad] entries are
selected, the L.E.D. [light emitting diode] display continues to read “FILL”)...
1. Dryer is not in level position.
2. Broken connection between level switches.
3. Level switches need to be adjusted.
4. Failed keyboard (touchpad) label assembly.
5. Failed microprocessor controller (computer).
M. Microprocessor controller (computer) will only accept certain keyboard (touchpad) entries...
1. Failed keyboard (touchpad) label assembly.
2. Failed microprocessor controller (computer).
N. Microprocessor controller (computer) locks up and L.E.D. (light emitting diode) display reads
erroneous messages 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 evident ...
a. Failed microprocessor controller (computer).
b. Failed keyboard (touchpad) label assembly.
O. Dryer stops during a cycle, microprocessor controller (computer) buzzer (tone) sounds for five
(5) seconds, L.E.D. (light emitting diode) display reads “dSFL” for approximately thirty (30)
seconds and then returns to “FILL”...
1. Loose connection somewhere between the microprocessor controller (computer) and the micro-
processor temperature sensor.
P. Dryer stops during a cycle, microprocessor controller (computer) buzzer (tone) sounds for a few
seconds, and then microprocessor controller (computer) L.E.D. (light emitting diode) returns to
“FILL”...
1. Loose connection somewhere in the main power circuit to the microprocessor controller (computer).
