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 (basket) 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 (basket) 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/door circuit. If the machine was not active and the lint
drawer/door was opened the display would read “REAdY.” If a program attempt was made with the lint
drawer/door open the display would read “LINT dOOR” with an audio indication. If the machine was
active and the lint drawer/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 (basket)
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 (basket) 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
(basket) temperature is below 100º F upon failure the machine will shut down and display “TEMP SENSOR
FAIL CHECK TEMP SENSOR FUSE” with an audio indication. 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 discontinued (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 tumbler (basket) rotation 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 non active mode (No ROTATE SENSOR).
