I have had no luck pulling up your schematic on line so it is a little tough going by the picture. It appears you have a standard spark igniter in the front and a thermocouple sensor in the rear of the photo. On this style unit, when you turn on the tstat, it sends a small amount of gas to the burner and the igniter is supposed to light the burner, the flame will stay small until it heats up the thermocouple enough to open the valve. Now am I correct in you stating when you try to light it you can hear the igniter trying to spark but no spark is present? Or when you turn on the oven the top burners are sparking and the oven one isn't? Most of these units spark the burners and the oven all when any knob is turned. If when you turn the knob on for the oven your tops spark, that would mean your switch is good and we would need to concentrate on the igniter itself or the module. Please provide a schematic if possible. Your unit might use a separate module for the oven, once I see a schematic we should be able to figure it out real easy. Avanti's are not that common, but all the ignition systems are basically the same.
