Stove ignition issues
The stove and oven ignition runs on a small inverter which is located under the stove. To reach it, go into the port hull. Close the sliding door. This will reveal a cabinet, just right of the sliding door. Open the door of the cabinet and remove the rear panel. You will find the inverter including a fuse box. If you have issues, this is where to start looking.
This small inverter is switched on/off together with the fridge on the switch panel. In a way that makes sense, because when you cook, you probably have the fridge on too. But an inverter uses some current, even in standby mode. To reduce the energy consumption by one or two amps, you can move the connection of the inverter on the switch panel to an un-used switch. For instance on the bottom right.
