for assistance and to possibly avoid a service call.  

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.”

Is the lint screen clogged with lint?

Use 4" (102 mm) diameter vent material.

Is the exhaust vent or outside 

exhaust hood clogged with lint, 

restricting air movement?

Are fabric softener sheets blocking 

the grille?

Is the exhaust vent the correct 

length?

Is the exhaust vent diameter the  

correct size?

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.”

Proper operation of dryer cycles requires temperatures above 

45ºF (7ºC).

Is the dryer located in a room with 

temperature below 45ºF (7ºC)?

Is the dryer located in a closet?

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.

“AF” (low airflow condition):

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.”

Separate the load to tumble freely.

Has the Air Only modifier been 

selected?

Is the load too large and heavy to dry 

quickly? 

Select the right temperature for the types of garments being 

dried. See “Additional Features.”

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.

Are clothes coming out of the Quick 

Refresh cycle with damp or wet 

spots?
