What should I do when the 'Check Vent' indicator lights up on my dryer?

The Check Vent indicator means there is a blocked vent or low airflow condition. Clean the lint screen, check the vent run from the dryer to the wall for crushing or kinking, and confirm the exterior vent exhaust hood is free of lint and debris. The dryer will continue to run when this indicator is present, and you can touch any key to clear it from the display. If the problem persists, contact a venting specialist. (Page 17)
