MAINTAINING THE EXHAUST SYSTEM

The most common cause of dryer problems is poor exhaust venting. Poor exhaust venting may result from the
following conditions:
• DIRTY OR DAMAGED EXHAUST DUCTS
• WRONG VENT MATERIAL
• RESTRICTED OR DAMAGED VENT HOOD
• EXCESSIVELY LONG VENT
• THE USE OF PLASTIC OR FOIL VENTING
Maintaining the Exhaust System
Vent ducts should be checked for lint buildup and
cleaned at least once per year. If any noticeable
reduction in drying performance occurs, check the ducts
for obstructions and blockages.
If the CHECK VENT indicator illuminates, the exhaust
system should be checked immediately for damage or
obstructions. The CHECK VENT indicator signals a serious
reduction in exhaust airflow which will greatly reduce
energy efficiency and increase drying times. Damaged
or restricted exhaust systems are not covered by the
dryer warranty. Damage to the dryer that is caused by
damaged, restricted, or otherwise inadequate exhaust
systems is not covered by the dryer warranty.
CHECK VENT Indicator
The CHECK VENT warning system is designed to help you
avoid the reduced performance caused by restrictions
in the household exhaust system. The CHECK VENT
indicator illuminates to alert you when problems in the
system occur, so you can have them repaired.
While you should always check and maintain your
exhaust system regularly, the CHECK VENT warning
system will detect and alert you if serious problems
develop in your home's exhaust system. This includes
exhaust systems that are unsatisfactory for any reason
including a blockage in the venting, crushed/kinked
venting, or venting which exceeds the maximum
recommended length requirement as described in the
installation section.
NOTE: The total length includes the length from the back
of the dryer to the outside vent hood, PLUS a factor for
every 90° elbow in the exhaust system. For example, if
the distance from the back of the dryer to the vent hood
is 30 feet, and there are four elbows in the system, then
it exceeds the 28 foot maximum length allowed for those
conditions.
The CHECK VENT indicator on the control panel will alert
you that the exhaust system is not moving enough air
from the dryer to the outside. This lack of airflow will lead
to long dry times, poor drying and possibly dryer failure.
As a reminder, external dryer venting is considered part
of your home and is not covered by the product warranty
or protection agreements. There are services available for
cleaning/maintaining the external venting.
CHECK VENT Operation
The CHECK VENT system uses components already in the
dryer. By monitoring these components over the course of
several cycles, the control is able to determine how much
restriction there is in the exhaust system. If it detects a
high level of restriction, it will turn on the CHECK VENT
light to alert you to the condition. The dryer will continue
to operate after the light comes on, but you should have
the exhaust system cleaned or repaired immediately to
avoid longer dry times and higher energy consumption.
IMPORTANT: In order for a dryer to properly and
efficiently dry your clothes, it is extremely important that
the exhaust system is as short and clean as possible. It
MUST be less than the maximum installation requirements
as outlined in the installation section. It is also very
important that you make sure that when the dryer is
installed, the exhaust system is clean and clear of any
restrictions and is not kinked or crushed.
Failure to meet these guidelines will result in long dry
times, increased energy consumption and possibly even
clothing damage or dryer failure. When exhaust system
restrictions become extreme, the CHECK VENT light will
blink to alert you to the condition so you can have the
exhaust system cleaned or repaired.
1
To prevent false alarms and for increased reliability,
the dryer will monitor the exhaust condition for
several loads. If multiple, consecutive cycles exceed
the restriction limits, the control will blink the CHECK
VENT indicator.
2 A blinking CHECK VENT indicator means the external
venting should be checked for potential restrictions as
soon as possible.
3
The CHECK VENT indicator will remain active
(blinking) until the restriction is resolved AND the
control has verified the improved airflow for
several cycles.
4
After the exhaust is cleaned or repaired, it will take
several cycles for the CHECK VENT indicator to reset
and turn off the light.
NOTE: The CHECK VENT indicator is designed to
measure performance over several consecutive cycles
before activating or deactivating, to avoid false alarms.
A very large load, such as a large comforter, could cause
the CHECK VENT system to sense that the exhaust system
is restricted, but this would not cause the light to blink.
However, if several large loads were to run back to back,
the CHECK VENT indicator could be activated.
