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).
