ABSTRACT:
Methods and apparatuses of for detecting lint are disclosed. In one embodiment, a light is directed to a plate. The light can be being emitted by a light source. A reflectometer is calibrated to a specific thermal emissivity of the plate. The thermal emission resulting from the light directed to the plate is received at the reflectometer. Lint is permitted to deposit on the plate. A change in thermal emission is detected if lint deposits on the plate. The change in thermal emission can be detected by the reflectometer. An indication that lint is present within the clothes dryer is provided if a change in thermal emission is detected by the reflectometer.
