Product review (5 stars): Just what we needed.
This is a thermal fuse for a dishwasher, a very common failure that often leads to unnecessary and costly appliance replacement. Ours lasted over 10 years before blowing and upon replacement has been going strong for several months. A simple continuity test with a multimeter will tell you if it has blown.

You may be thinking you could get a handful of the actual fuses themselves for a fraction of this price. However, a novice shouldn't attempt to solder these fuses as they will likely blow from the heat. (It's a thermal fuse!) Also, a replacement wiring harness is highly recommended as an aged wire or connector raises resistance (~heat) which will cause premature failure of your new fuse and is often the root cause for failure to begin with.

Do the continuity check, save yourself a headache and bring your dishwasher back to life.
