Is Gas Supply Connected and Shutoff Valve Open (gas models only)?

Make sure the dryer is connected to the gas supply.

The drum of a gas dryer will turn, but the dryer will not heat if the gas shutoff valve is closed. Open the gas shutoff valve in the supply line. The valve is open when the handle is parallel to the gas pipe. 

Is the Lint Screen or Vent Clogged?

An AF (Restricted Air Flow) or "Check Vent" error code indicates that the lint screen or vent is clogged; the vent is crushed, kinked, or has too many turns. The dryer will continue to run when the is error is present. Touch any key to clear the code from the display and return to the estimated time remaining.  

What cycle was selected?

Cycle selection is important.  If the clothes don't reach the desired dryness level try selecting a different cycle such as "Regular".  

Quick Dry and Rapid Dry are timed cycles designed to dry smaller loads. If clothes are too wet after the cycle has completed, try running the Quick Dry or Rapid Dry cycle again. For best performance, use an automatic cycle.

The EcoBoost™ option will default on only for the Regular/Normal cycle and is only available on that cycle. This option allows you to increase your energy savings by using a slightly lower heat level. The EcoBoost™ option will increase drying times by approximately 40 minutes, which will be reflected on the LED Display. If optimal time is desired, touch ECOBOOST to turn off this option.

Is the dryer new?

If you connected a new dryer to the old house venting, you may still have long dry times. Venting going to the outside of the home needs to be cleaned every one to two years or as needed when dry performance has decreased. This will depend on the frequency of use, types of items dried, pet hair, etc. Dryers need good airflow to the outside for clothing to dry and for optimal performance.

Verify house vent (behind the dryer) is clear of obstructions    

If a dryer is heating, but still has long dry times, the likely cause is a vent issue. Venting going to the outside of the home needs to be cleaned every one to two years or as needed when dry performance has decreased. This will depend on the frequency of use, types of items dried, pet hair, etc. Dryers need good airflow to the outside for clothing to dry and for optimal performance.

Before calling for service, check your house vent going to the outside. Make sure that the vent material is not crushed or kinked. Verify that the vent is clear of lint or other obstructions. Clean venting the entire length starting at the back of the dryer to where it exits your home. View the image below:

You can also contact a professional vent cleaning service and have your vent inspected for obstructions. This should be done at least once every year.

A dryer vent test, part #W11224254, is available for all dryers. This vent test kit will help you to determine if the venting is restricted and needs to be cleaned. To order, contact Customer Service.

Is the Lint Screen Clean? 

The lint screen will be located either on top of the dryer or in the door opening of the dryer. A screen blocked by lint can increase drying time. It is important to clean your lint screen after every use.

If you use fabric softener on a regular basis, your lint screen may have residue build-up that is typically not visible. This residue should be cleaned occasionally for better drying performance. Click the link below for more information.

Verify outside Exhaust Hood is not blocked or restricted

Exhaust hoods must be at least 12" (305 mm) from the ground or any object that may obstruct exhaust (such as flowers, rocks, bushes, or snow).

It is possible for debris, such as animal nests, to cause an obstruction in the venting. Clear all debris from the hood, and attached venting.

Is the house vent crushed?  

Rigid or Flexible metal venting is recommended for use on all dryers. Other materials (aluminum foil, plastic) are NOT recommended because they can easily collapse or be crushed. Your dryer may get pushed back into the venting material and can get crushed behind the dryer. See images below:

Vent length and elbows are correct

The vent system chart below provides venting requirements that will help achieve the best drying performance.

• Replace any plastic or metal foil vent with a rigid or flexible heavy metal vent.

• Use only 4" diameter heavy metal exhaust vent material. Larger or smaller diameter material will reduce good air movement and cause longer drying times.
