7.bURNER FLAME FAIL- This routine allows two (2) Flame out retries to occur before proceeding into the error. The count of two (2) will be established every time the call for heat was to occur. Only if it reaches the count of two (2) before the tumbler temperature has reached the set temperature will this error be triggered. The machine will run with no heat for three (3) minutes or until the temperature drops below 100º F. If the tumbler temperature is below 100º F 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.

8.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.

9.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.

10.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." If the tumbler temperature is above 100º F the machine will continue to display "TEMP SENSOR FAIL CHECK TEMP SENSOR FUSE" with an audio indication and run with no heat for three (3) minutes or until the temperature drops below 100º F. If the tumbler temperature is below 100º F upon failure the machine will shut down and display "TEMP SENSOR FAIL CHECK TEMP SENSOR FUSE" with an audio indica- tion. 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 cor- rected 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."

11.ROTATE SENSOR FAIL- Indicates a rotational sensor circuit failure meaning that there is a fault somewhere in the basket (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).
