What does the 'Check Vent' indicator light mean?

The Check Vent indicator shows the status of airflow through the dryer and vent system. During the sensing phase at the beginning of a cycle, this light will come on if a blocked vent or low airflow issue is detected and will stay on for the entire cycle. The light will be cleared when selecting a new cycle, touching POWER, or opening the door after the cycle completes. This feature is available during Sensor and Steam cycles only.
