Abstract
A dryer appliance includes a drum defining a chamber for receipt of clothes for drying, an air handler for urging a flow of air through the chamber, and a trap duct in fluid communication with the chamber and comprising a lint filter for filtering lint from the flow of air exiting the chamber. A lint detection assembly includes an emitter for generating light and a receiver for detecting the light that is transmitted through the lint filter, and a controller is configured to determine a lint level based at least in part on the light detected by the receiver, determine that the lint level exceeds a predetermined lint threshold, and implementing a responsive action, such as stopping the cycle, notifying the user, and/or updating an initial cycle time.
