Before Calling for Service

This dryer is equipped with an automatic error-monitoring system to detect and diagnose problems at an
early stage. If the dryer does not function properly or does not function at all, check the following before
you call for service.
Operation
Problem
The Flow Sense™
indicator remains
active after clearing
the restriction in
the venting.
Dryer will not turn
on
Dryer does not heat
Clothes take too
long to dry
Display show error
code nP
After clearing the restriction, the Flow Sense™ system requires multiple,
consecutive cycles to determine that the performance value has improved
before the Flow Sense™ indicator is reset.
• If the Flow Sense™ indicator remains active for more than five cycles after the
restriction has been cleared, call for service.
Power cord is not properly plugged in.
• Make sure that the plug is securely plugged into a grounded outlet matching the
dryer'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.
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.
• NOTE: Due to the design of electric dryers, it is possible for a circuit problem to
allow an electric dryer to run without heat.
Gas supply or service is turned off.
• Confirm that the house gas shutoff and the dryer gas shutoff valves are both
fully open. Even if gas is not supplied to the dryer, it will run and no error codes
will display. Verify that other gas appliances in the home are working normally.
ENERGY SAVER option selected (on some models)
• If using the Normal cycle, deselect the ENERGY SAVER option. The Energy
Saver option is selected by default. This option reduces energy use by adding
an air dry section to the beginning of the cycle. It is normal to feel no heat at the
beginning of the cycle while in ENERGY SAVER mode.
Exhaust ducts are blocked, dirty, or duct run is too long.
• Confirm that the exhaust duct is properly configured and free of debris, lint, and
obstructions. Make sure that outside wall dampers can open properly and are
not blocked, jammed, or damaged.
Load is not properly sorted.
• Separate heavy items from lightweight items. Larger and heavier items take
longer to dry. Light items in a load with heavy items can fool the sensor
because the light items dry faster.
Electric dryer power cord is not connected correctly, or house power supply
is incorrect.
• Check the power supply or the connection of the power cord to the terminal
block.
