Yes, there is a thermal fuse located behind the operator console. The part number for the replacement kit is 8193762. You can view an illustration at appliancepartspros.com. It sells for about $13 and the instuctions with a wiring harness are included with the kit.
NOTE: You MUST follow the instructions and use the wiring harness. There were some noted problems with certain model dishwashers
where the wire gauge on the thermal fuse was too small and would heat up causing the thermal fuse to blow prematurely. The replacement kit includes a wire harness with a larger gauge wire that handles current better, preventing the fuse from blowing prematurely. To ease your mind, there were no reports of fire hazard.
If you need to view a diagram of your dishwasher, enter your model number at the website mentioned for some excellent exploded view illustrations. The thermal fuse is listed as item 6 under the "Control Panel Parts" heading.
If you have any questions, please let me know. I hope this helps you.
