This cooker seems to be fine, but when turned up high to roast a joint it turns off after 10-15 minutes, and then comes on again after another 10-15 minutes (when it’s cooled down, I guess). I’m assuming this is a thermostat fault, but I don’t know how many stats there are, and which one might be at fault. Any ideas, please?
I think the best bet may be to get yourself an oven thermometer – the elements do cycle – the oven runs up to temperature, heat goes off, temperature slowly drops, thermostat clicks over, heat back on; ad infinitum.
