try this site as it has you manual and wiring diagrams with trouble shooting section.

Simply put, a pilot generator is a thermopile that generates millivolt power to operate a gas valve.

However, on your convection oven, yours operates on an electronic spark, which is generated by an electronic ignition control module.

It is probably the thermistor in the oven cavity top right hand corner sometimes these get scraped by sheet pans or scrape the wires
