This is for the thermal cutoff for the Samsung or Whirlpool heater can. We use and sell the Whirlpool-iterated model of the DC96-00887A which features a slightly higher thermal tolerance of 360*F.
Traditionally, Samsung Dryer thermal cutoffs feature one of the worst, lowest-tripping thermal points which gives them an infamous reputation regarding how often they trip. By using a slightly more robust, but exact-fitting part, it eliminates thermal trips that could happen by accident or slight vent restriction.
This thermal fuse is nearly universal beyond Samsung and Whirlpool products and may feature many other part# identifications.
