bURNER CONTROL FAIL – This routine monitors the ignition control’s gas valve output response. If the valve output signal is not present from the ignition control within the valve time limits the Phase 6 microprocessor controller (computer) determines the ignition control has failed. If this occurs when the cycle is active the machine will display “bURNER CONTROL FAIL.” If the tumbler temperature is above 100º F (38º C) the machine will continue to display “bURNER CONTROL FAIL.” The machine will run with no heat for 3 minutes or until the temperature drops below 100º F (38º C). If the tumbler temperature is below 100º F (38º C) upon failure the machine will shut down and display “bURNER CONTROL FAIL” with an audio indication.

bURNER FLAME FAIL – This routine allows 2 flame out retries to occur before proceeding into the error. The count of 2 will be established every time the call for heat was to occur. Only if it reaches the count of 2 before the tumbler temperature has reached the set temperature will this error be triggered. The machine will run with no heat for 3 minutes or until the temperature drops below 100º F (38º C). If the tumbler temperature is below 100º F (38º C) upon failure, the machine will shut down and display “bURNER FLAME FAIL” with an audio indication. This process will occur every time the heat output is active.

MAIN DOOR – This monitors the door circuit. If the machine was not active and the main door was opened the display would read “REAdY.” If a program attempt was made with the main doors open the display will read “MAIN dOOR” with an audio indication. If the machine is active and the main door was opened the display would read “MAIN dOOR” with no audio indication and the dryer will shut down. Once the main door has closed the display would read “PRESS START” press the “ENTER/START” key and it will continue the programmed cycle.

LINT dOOR – This monitors the lint drawer and door circuit. If the machine was not active and the lint drawer and door was opened the display would read “REAdY.” If a program attempt was made with the lint drawer and door open the display would read “LINT dOOR” with an audio indication. If the machine is active and the lint drawer and door was opened the display would read “LINT dOOR” with no audio indication and the dryer will shut down. Once the lint door was closed the display would read “PRESS START” press the “ENTER/START” key and it will continue the programmed cycle.

TEMP SENSOR FAIL CHECK TEMP SENSOR FUSE – This routine monitors the tumbler temperature. When the temperature sensor or fuse opens with the machine not active the display will read “TEMP SENSOR FAIL CHECK TEMP SENSOR FUSE” with an audio indication. If the machine was active at the time that the temperature sensor or fuse opened the display would read “TEMP SENSOR FAIL CHECK TEMP SENSOR FUSE.” The display will continue to read “TEMP SENSOR FAIL CHECK TEMP SENSOR FUSE” an audio indication will sound for approximately 5-seconds, every 30-seconds until the problem is corrected or the power to the dryer is disconnected (and the problem is corrected).

NOTE: Once the Phase 6 microprocessor controller (computer) detects a problem in the heat circuit, it updates every 30-seconds, so that if the problem was a loose connection in the circuit, which corrected itself, the

“TEMP SENSOR FAIL CHECK TEMP SENSOR FUSE” condition would automatically be cancelled and the display will return to “REAdY.”

ROTATE SENSOR FAIL – Indicates a rotational sensor circuit failure meaning that there is a fault somewhere in the tumbler 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.

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).

L.E.D. Display Indicators

The L.E.D. indicator dots located on the top portion of the display indicates 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).

L.E.D. Display Indicator Number 1

For Optional Reversing Models: This indicator dot is on when the drive (tumbler) motor is operating in the forward mode (clockwise direction).

L.E.D. Display Indicator Number 2

For Optional Reversing Models: This indicator dot is on when the drive (tumbler) motor is operating in the reverse mode (counterclockwise direction).

L.E.D. Display Indicator Number 3

Heat Circuit Indicator: This indicator dot is on whenever the Phase 6 OPL microprocessor controller (computer) is calling for the heating circuit to be active (on).
