controller display will show a flashing “185”. Each press of the UP arrow key will 
increment the temperature by five degrees. 
6) Now, press and release the SELECT/ENTER touch pad key on the dryer controller.
The number “185” will stop flashing and the temperature L.E.D. will switch off. The 
dryer control display will now show a number “2”, the cool down L.E.D. will 
illuminate, and the programming L.E.D. and dry cycle 5 L.E.D. will remain on. 
7) Press and release the SELECT/ENTER key on the dryer controller touch pad, since
the desired cool down time is two minutes. After you press the SELECT/ENTER 
touch pad key on the controller, the cool down L.E.D. will switch off. The dryer 
controller display will show “nrEv”, the reversing L.E.D. will illuminate, and the 
programming L.E.D. and dry cycle 5 L.E.D. remain on. 
8) Press and release the UP or DOWN arrow key once. A flashing “rEv” will appear on
the dryer controller display and the reversing L.E.D. will start to flash. Each press 
and release of either arrow key will toggle between the reversing mode (“rEv”) and 
non-reversing mode (“nrEv”). 
9) Press and release the SELECT/ENTER key. Once this key is pressed and released,
the programming L.E.D. and the reversing L.E.D. will switch off. The dry cycle 5 
L.E.D. will remain on. The flashing “rEv” will stop flashing and remain on. 
You are now ready to start the new dry cycle. This new dry cycle will be in effect for 
one dry cycle only. After the dry cycle is done, or if the STOP touch pad key on the 
dryer controller is pressed and released twice, consecutively, the cycle 5 program will 
revert to the factory default settings. 
 
If you press the START touch pad key on the dryer controller, the controller display 
will change from “rEv” to the number “42” and dry cycle 5 will begin.

dryer controller until the operator physically changes them again. The factory default settings 
can be restored in the dryer controller by pressing the default settings pushbutton on the back 
(component) side of the dryer controller circuit board. It is labeled and located at the lower 
middle side of the printed circuit board, as you face the component side of the board. It must be 
pressed and held down for at least three seconds. 
 To permanently change a dryer controller cycle, follow the procedure below. Things that are 
displayed on the 4-digit numeric display will be in “quotation marks”. Keys on the touch pad 
that physically need to be pressed will be in CAPITAL AND BOLD LETTERS. 
 If, at any time, you want to escape the permanent programming mode while changing the 
settings, you can press and release the STOP key on the dryer controller touch pad if the 4-digit
