it doesn't have a toc which cuts it out . the toc is in the twin stat arrangement above the heater at the rear and is simply a one shot stat which fails and causes no heat to be produced this can only be replaced not reset , i have had a similar fault caused by the start relay behind the front console panel there was a fault on early versions of these so suggest you look into that , you can see it from the top if you remove the top panel , also have you checked your mains lead has not got a broken /chafed wire or moulded plug got a fault , all of these would cause symptoms ,not an overheat device
