Now it's time to find a replacement. The original thermal fuse comes from China and here's a link for the TAMURA TAM Thermal Fuse Cutoff 127℃ 250V 3A H4X Square Temperature Switches. A close up picture is shown.

An alternative thermal fuse from RadioShack, which in fact is cheaper (~$1.40) than options from ebay.

The Radio Shack thermal fuse has a high ampere rating, but from what I read having a higher ampere rating will be suitable. The temperature is what is important.
