A:Answer Hello there, thank you for your detailed question about the lint sensors in the DLE7150W dryer. The lint sensors monitor airflow and lint buildup during operation. If the sensors detect a significant reduction in airflow, which could happen if the lint filter needs cleaning or if there’s a blockage in the venting system, a warning light will illuminate on the control panel after several loads. This is a helpful reminder for homeowners to check and clean the lint filter and any potential obstructions in the vent. Additionally, if an external factor, like a bird's nest on a roof guard, blocks airflow, it could also trigger the sensor alert. Regular maintenance of both the lint filter and venting system is crucial for optimal performance.
