inch (1.5 cm). The dryer should be checked while
the dryer is running with no load.
Activating the Installation Test
NOTE
• The appliance should be cool before starting this
test. If the appliance was warmed up during
installation, run the Air Dry cycle for a few
minutes to reduce the interior temperature.
• Before starting the test, please check that the
voltage is 240V±6%. If the voltage is less than
225V, a duct clogging error may occur even
though the duct is not actually clogged (electric
model only).
1
Do not load anything in the drum for this test,
as it may affect the accuracy of the results.
2
Press the Power button and touch the upper
left corner of the display 10 times slowly. And
then select Dryer after selecting Install
Mode.
• This button sequence activates the
installation test. A message will display if
the activation is successful.
3
Press the Start/Pause button.
• The appliance will start the test, which will
last a few minutes. The heat will be turned
on and the temperatures in the drum will be
measured.
4
Check the display for results.
• During the test cycle, monitor the error
messages displayed on the control panel. If
the duct blockage message has not been
displayed when the cycle ends, the exhaust
system is adequate. If the exhaust system is
severely restricted, the duct blockage
message will be displayed. Other problems
may also be shown with error messages.
See the chart on the next page for error
code details and solutions.
• If the duct blockage displays that the
exhaust system is severely restricted, have
the system checked immediately, as
performance will be poor.
5
End of cycle.
• At the end of the test cycle, a message will
display. The test cycle will end and the
appliance will shut off automatically after a
short delay.
Check the Duct Condition
If the duct blockage message is displayed,, check
the exhaust system for restrictions and damage.
Repair or replace the exhaust system as needed.
NOTE
• When the appliance is first installed, this test
should be performed to alert you to any existing
problems with the exhaust duct in your home.
However, since the test performed during
normal operation provides more accurate
information on the condition of the exhaust duct
than the installation test, the percentage of
blockage displayed during the two tests may not
be the same.
• Do not interrupt the test cycle, as this could
result in inaccurate results.
• Even if no duct blockage message is displayed
during the test cycle, some restrictions may still
be present in the exhaust system. Refer to the
Venting the Dryer section of this manual for
complete exhaust system and venting
requirements.
