Leisure Cuisine Master 100 does not heat up and light does not work?

Hi I have a Leisure Cuisine Master 100 (RCM10FR/SP) which is few years old. The right hand conventional oven has stopped heating up. The bulb had blown but have replaced it but the bullb still does not come on. I have checked both elements top one 65 ohms and bottom one 50 ohms. Unable to test the thermostat as it requires stripping down the whole top of the oven. I would have thought that even if it was the thermostat the bulb should still operate or do I have a much deeper problem. Any help would be much appreciated.
