I have been given a diplomat range cooker model adp5330, think it's been in storage for a while, turned it on fan started OK started heating up then tripped rcd, tried next day same thing, today I tried with different elements top & bottom oven elements, same thing. Started heating and after approx a minute tripped rcd, is this a thermostat problem?? I am suitably qualified to take a look 18th edit, apprenticeship etc but have no ideas about cookers! Please help
