Product review (5 stars): Good Thermal Fuse Replacement Part
My Whirlpool dishwasher completely died after about 3 years of use. We started a load of dishes and when we got up the next morning, there was nasty water in the bottom of the machine and the dishes were still dirty.  After some looking around on the internet, I deduced that it was probably the Bimetal Fuse (or Thermal Fuse as it is also called).  Once I got the control panel opened up, it was a simple matter to check the continuity of the existing fuse with a multi-meter.  If there is continuity, the fuse is o.k.  If not, you need this replacement.  Installation was very easy and only required a wire stripper and a small flathead screwdriver.  Once I put the panel back together, the dishwasher fired right up.  Perfect.
