Test Vent Kit

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. 

REMINDER: Venting going to the outside of the home needs to be cleaned every one to two years or as required when dry performance has decreased. Dryers need proper airflow to the outside for clothing to dry and for optimal performance. 

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 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. See the images below.

Verify house vent is clear of obstruction

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 required when dry performance has decreased. This will depend on the frequency of use, types of items dried, pet hair, etc. Dryers need proper 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:

Is the 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.

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 obstruct the venting. Clear all debris from the hood and attached venting.

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 essential to clean your lint screen after every use. The lint screen should also be cleaned of detergent/fabric softener residue occasionally. Click the link below for more information.

What cycle was selected?

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.
