Diplomat Fan Oven APL 3201 IX - No heat, fan, grill of lights?

However, the clock on the front is still ticking, so I'm assuming it's getting power?

Main oven and grill provide no heat. Internal light does not come on. Fan does not come on. Turning the heat dial does produce a click between 0 and 50, which I assume means that that is still working?

I'm assuming that given almost everything has died it's not the main element. Any suggestions what I should look for next, or should I pull it out and start checking power is available at all the appropriate points? Does such an electric over have safety cutout thermostats and would their activation produce such symptoms?
