This dishwasher repair guide explains how to replace the bi-metal thermal fuse in the control panel. The dishwasher thermal fuse is a safety device that shuts power to the controls off—making the control panel unresponsive to commands—if there's a short circuit in the wire harness. The fuse can also blow or trip due to a failure of a major component such as the heating element or pump. You can replace the dishwasher's blown thermal fuse in less than 30 minutes, using a manufacturer-approved replacement part.
These instructions work for replacing a blown thermal fuse in Kenmore 665-series, Kenmore Elite, Whirlpool and KitchenAid dishwashers.
