N. Microprocessor controller (computer) will only accept certain keyboard (touchpad)

entries…

1. Failed keyboard label (touchpad) assembly

O. Microprocessor controller (computer) locks up and L.E.D. display reads erroneous

message (s) or only partial segments…

1. Transient power voltage (spikes)…disconnect power to dryer, wait one (1) minute and

reestablish power to 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, L.E.D. display reads “dSFL” for approximately 30 seconds

and then return to “FILL”…

1. Loose connection somewhere between the microprocessor controller (computer) and

the microprocessor temperature sensor

Q. Dryer stops during a cycle, microprocessor controller (computer) buzzer (tone)

sounds for a few seconds, and then the microprocessor controller (computer)

L.E.D. display returns to “FILL”…

1. Loose connection somewhere in the main power circuit to the microprocessor

controller (computer)

R. Microprocessor controller (computer) L.E.D. display reads “SEFL”…

1. Microprocessor controller (computer) program (Program Location 2) is set incorrectly

in the active mode (“Sen”) where dryer is not equipped with the

optional

rotation

sensor program

must be

set as “Sen”

2. Rotational sensor circuit (optional) failure…fault somewhere in the basket (tumbler)

rotation or circuit

a. Basket (tumbler) not rotating

1) Broken basket (tumbler) drive V-belt(s)

2) Failure in drive motor circuit…refer to part B, Part C, and Part D on

b. Bad rotation sensor

c. Broken wire or connection between rotation sensor and microprocessor controller

(computer)

S. Microprocessor controller (computer) L.E.D. display reads “Hot”…
