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.  

Is Gas Supply Connected and Shutoff Valve Open?

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 Clean? 

The lint screen is located either on the top of the dryer or in the door opening of the dryer. The screen must be clear of any lint/debris.

Is the outside vent or exhaust clogged with lint/debris and restricting air movement? 

Ample air flow must be permitted for proper dry time. Use the images below to troubleshoot and guide your vent cleaning:

Venting going to the outside of the home needs to be cleaned every one to two years or as required when dry performance decreases. 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.

Are you using the right type of vent? 

Use only rigid metal or flexible metal vent material. 

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.

Difference between Auto Dry and Timed Dry: 

During Automatic Cycles, drying air temperature and moisture level is sensed in the load. This sensing occurs throughout the drying cycle, and the dryer shuts off when the load reaches the selected dryness. 

With Timed Dry, the dryer runs the amount of time set and sometimes results in shrinkage, wrinkling, and static due to over-drying. Use Timed Dry for the occasional damp load that needs a little more drying time or when using the drying rack.
