What to do if all the lights are off and my KitchenAid Kitchen Aid KICU500X Cooktop isn't responding?

If all the lights are off on your KitchenAid Cooktop's user interface and the cooktop isn't responding, try the following steps: * Disconnect the power. * Check the continuity between L2 on the terminal block and both L2 terminals on the EMI filter board. If there are no lines, replace the blown thermofuse harness. * Check the continuity of the fuses on the EMI board; if any are blown, replace them with new ones. * Change both control boards. * Change the User Interface. * After each of these steps, remember to replace all parts and panels, reconnect the power, and check if the cooktop is working. Also, reconfigure the cooktop by following the directions in 'Manual Configuration Mode.'
