ABSTRACT:
A device and method for detecting lint in a clothes dryer are disclosed. A lint detector is positioned within the clothes dryer. A light source is also positioned within the clothes dryer. The lint detector has a surface that receives light emitted by the light source. Further, the lint detector has a photocell that receives light reflected from the surface if lint covers the surface. A determination is made as to whether a threshold amount of light has been received. An indication such as the activation of a warning light can be provided if the threshold amount of light is received. Another response is shutting the clothes dryer down.
