11. ROTATE SENSOR FAIL - Indicates a rotational sensor circuit failure meaning that there is a fault

somewhere in the tumbler (basket) rotating circuit, or the Phase 6 OPL microprocessor controller
(computer) program related to this circuit (Program Location 2) is set incorrectly. In the active mode
it should be (ROTATE SENSOR ACTIVE), if the dryer is not equipped with the optional rotational
sensor it should be set in the nonactive mode (No ROTATE SENSOR).

NOTE: RPM - This routine monitors the timing response from the existing rotational sensor input and

derives a RPM measurement. To display this RPM measurement (press the “ENTER/
START”

key once and release, then press the “ENTER/START”

key a second time and

hold. This will display the RPM measurement). The rotational sensor must be active for
operation of this feature.

12. CHECK MAIN FUSE - Indicates that the circuit fuse protection which is located on the back side

of the Phase 6 microprocessor controller (computer) the display would read “CHECK MAIN FUSE.”
If the display continues after the fuse has been replaced then it is the fault of the Phase 6 microprocessor
controller (computer).

B. L.E.D. (light emitting diode) DISPLAY INDICATORS

The L.E.D. (light emitting diode) indicator dots located on the top portion of the display indicates the various
Phase 6 OPL computer output functions while a cycle is in progress. These indicator dots (as shown in the
illustration below) DO NOT necessarily mean that the outputs are functioning. They are only indicating that the
function output should be active (on).

1. L.E.D. DISPLAY INDICATOR NUMBER 1

a. For Optional Reversing Models:

1) This indicator dot is on when the drive (tumbler [basket]) motor is operating in the forward mode

(clockwise [CW] direction).

2. L.E.D. DISPLAY INDICATOR NUMBER 2

a. For Optional Reversing Models:

1) This indicator dot is on when the drive (tumbler [basket]) motor is operating in the reverse mode

(counterclockwise [CCW] direction).

3. L.E.D. DISPLAY INDICATOR NUMBER 3

a. Heat Circuit Indicator:

1) This indicator dot is on whenever the Phase 6 OPL microprocessor controller (computer) is

calling for the heating circuit to be active (on).
