What is the Check Vent indicator light and what should I do when it turns on?

The Check Vent indicator lights up when a blocked vent or low airflow issue is detected during the sensing phase at the beginning of a cycle. The dryer will continue to run, but you should clean the lint screen, check the vent run for kinks or crushes, and confirm the exterior exhaust hood is free of lint and debris. If the issue persists, have your entire home venting run professionally cleaned. (Page 17)
