FAULTS

EXHAUST PROBE

An  exhaust  probe  fault  occurs  when  the  control  detects  that  the  exhaust  temperature  transducer  is  reading  a
temperature that is out of the probe’s normal operating temperature range for more than 3-seconds.  There is an
automatic fault clearing feature for this fault.  If the fault condition no longer exists, the control will clear the fault
condition and return to READY Mode.

AXIAL PROBE

An axial thermistor probe fault occurs when the control detects that the axial thermistor is reading a temperature that
is out of the probe’s normal operating temperature range for more than 30-seconds, usually an open or shorted probe
condition.  There is an automatic fault clearing feature for this fault.  If the fault condition no longer exists, the control
will clear the fault condition and return to READY Mode.

SAIL SWITCH CLOSED

A sail switch closed fault occurs when a cycle is starting up from either READY Mode, PAUSE Mode or any other idle
state.  Once a temperature/cycle is selected the control will start the time and verify the sail switch is open, if it is not,
the control will display on the screen that the control is “STARTING” and will not turn on the FAN, DRIVE or HEAT.
The control will allow the sail switch 10-seconds to open before the control faults out with a SAIL SWITCH CLOSED
FAULT.  Once a SAIL SWITCH CLOSED FAULT is detected the control will log the fault and will not allow the cycle to
continue.  The control will display “SAIL SWITCH CLOSED FAULT, SELECT CYCLE TO RESTART, when the fault is
detected.

SAIL SWITCH OPEN

A sail switch open fault occurs when a cycle is starting from either READY Mode, PAUSE Mode or any other idle
state.  If the sail switch does not close within the allotted 10-seconds the control will log the fault and will not allow the
cycle to continue.  The control will display “SAIL SWITCH OPEN FAULT, CHECK MAIN DOOR AND LINT ACCESS
AND SELECT CYCLE TO RESTART”.  A sail switch open fault can also occur once a cycle is in process.  If the control
detects that the sail switch has opened, the heat will immediately turn off and if the sail switch fails to close within the
allotted 30-seconds, the control will fault and display “SAIL SWITCH OPEN FAULT, CHECK MAIN DOOR AND LINT
ACCESS AND SELECT CYCLE TO RESTART”.

ROTATION SENSOR FAULT

A rotation sensor fault occurs when the control is in a cycle and does not detect any rotation sensor pulses in more
than 10-seconds.

EXHAUST HIGH TEMP FAULT

An exhaust high temperature fault occurs when the exhaust probe is detecting a tumbler temperature that is 20° F
above the maximum dryer temperature set point for more than 10-seconds.

BLOCKED COIN DROP

This fault occurs if the control senses a blockage in the coin input.  If the coin input is blocked for more than 8-
seconds the control will go to out of order and will not allow the control to start a cycle.  This fault has both automatic
and manual fault clearing.  If the condition is corrected the control will recover from out of order immediately after the
blockage is no longer seen.
