Customer Questions and Answers for Dishwasher Thermal Fuse by Whirlpool

Jeff, if the thermal fuse was "open" there would be no lights or operation on the control panel or the dishwasher. The flashing "normal" light would indicate a "stuck" or inoperative button on the control panel WP8558208. "WON’T RUN AND LED ABOVE KEY(S) IS BLINKING > Stuck key(s) or shorted circuit(s) in keypad. > Shorted circuits or connections on the control that read the keys." If you already replace the control panel/keypad assembly, re check and make sure the touchpad ribbon is properly connected, and is not kinked, creased or twisted. Thanks and Good Luck
