  If your Webasto Cooker isn't responding, start by checking the operating voltage at the control unit's voltage connector. If it's under 10.7 VDC, inspect the control unit, control panel, and control panel cable. If the voltage is adequate, check the main cable connections and the main switch. Also, check the fuses on the main cable and control unit. Finally, ensure the battery voltage exceeds 10.7 VDC.
