Possible Cause
Temperature sensor failure.

incorrectly.

has too many turns/restrictions.
Partial blockage of the ductwork
due to lint buildup or other
foreign object.
The appliance has detected a
restriction in the external dryer
venting.

Flow Sense system requires
multiple, consecutive cycles to
determine that the performance
value has improved before the
TM
Flow Sense indicator is reset.
Lint filter not cleaned properly.

Solutions
Turn off the dryer and call for service.
Check the connection of the power cord
to the terminal block.
Install a shorter or straighter duct run. See
the Installation Instructions for details.
Ductwork should be checked/cleaned
immediately. Dryer can be used in this
condition, but drying times will be longer
and energy consumption will increase.
If exhaust restrictions are sensed by the
TM
Flow Sense system, the indicator will
remain on for 2 hours after the end of the
cycle. Opening the door or pressing the
POWER button will turn off the display.
TM
If the Flow Sense indicator remains
active for more than five cycles after
the restriction has been cleared, call for
service.
Remove the lint from the filter before
every load. With the lint removed, hold
the filter up to a light to see if it is dirty or
clogged. If it looks dirty, follow the cleaning
instructions. With some loads that produce
high amounts of lint, it may be necessary
to clean the filter during the cycle.
Do not use the dryer until the exhaust
system has been cleaned and/or repaired.
Using the dryer with a severely restricted
exhaust is dangerous and could result in
a fire or other property damage.
Check the outside dryer vent while the
dryer is operating to make sure there is
strong airflow.
If the exhaust system is extremely long,
have it repaired or rerouted.
Keep the area around the dryer clean and
free of clutter.
Check vent hood for damage or lint
clogging.
Make sure the area around the vent hood
is clear.
