Exhaust system is too long or has too many turns/restrictions.
• Do not use the appliance until the exhaust system has been cleaned and/or repaired.
Using the appliance with severely restricted exhaust is dangerous and could result in a fire
or other property damage.

Problem Possible Cause & Solution
Flow Sense TM
indicator shows four
bars during the
drying cycle.
Exhaust system is too long or has too many turns/restrictions.
• Install a shorter or straighter duct run. See the Installation instructions for details.
Partial blockage of the ductwork due to lint buildup or other foreign object.
• Ductwork should be checked/cleaned immediately. The appliance can be used in this
condition, but drying times will be longer and energy consumption will increase.
The appliance has detected a restriction in the external dryer venting.
• If exhaust restrictions are sensed by the Flow Sense TM 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.
The Flow Sense TM
indicator remains
active after clearing
the restriction in the
venting.
After clearing the restrictions, the Flow Sense TM system requires multiple, consecutive
cycles to determine that the performance value has improved before the Flow Sense TM
indicator is reset.
• If the Flow Sense TM indicator remains active for more than five cycles after the restriction
has been cleared, call for service.
The appliance will
not turn on.
Power cord is not properly plugged in.
• Make sure that the power plug is securely plugged into a grounded outlet matching the
appliance's rating plate.
House fuse is blown, circuit breaker has tripped, or power outage has occurred.
• Reset circuit breaker or replace fuse. Do not increase fuse capacity. If the problem is a
circuit overload, have it corrected by a qualified electrician.
