Possible Causes
Solution
The dryer will continue to run when this diagnostic code is
present. Touch any key to clear the code from the display and
return to the estimated time remaining.
Try the following:
Clean lint screen.
Check to see if the vent run from the dryer to the wall is crushed
or kinked.
Confirm the vent run from the dryer to the wall is free of lint and
debris.
Confirm the exterior vent exhaust hood is free of lint and debris.
Confirm your vent system falls within the recommended run
length and number of elbows for the type of vent you are using.
Refer to "Plan Vent System" in the Installation Instructions for
details.
Select a Timed Dry heated cycle, and restart the dryer.
If the message persists, have your entire home venting run
cleaned.
Lint screen should be cleaned before each load.
Run the dryer for 5-10 minutes. Hold your hand under the
outside exhaust hood to check air movement. If you do not feel
air movement, clean exhaust system of lint or replace exhaust
vent with heavy metal or flexible metal vent. See "Installation
Instructions."
Use only one fabric softener sheet, and use it only once.
Check that the exhaust vent is not too long or has too many
turns. Long venting will increase drying times. See "Installation
Instructions."
Use 4" (102 mm) diameter vent material.
Proper operation of dryer cycles requires temperatures above
45ºF (7ºC).
Closet doors must have ventilation openings at the top and
bottom of the door. The rear of the dryer requires 5" (127 mm)
of airspace, and the sides and front of the dryer require a
minimum of 1" (25 mm). See "Installation Instructions."
Select the right temperature for the types of garments being
dried. See "Additional Features."
Separate the load to tumble freely.
Under certain environmental or installation conditions you may
experience under drying. Select the Timed Dry cycle (30 min.
default time), which can be customized by choosing temperature
by touching TEMP and/or cycle time by touching the Time Adjust
up or down buttons.
