Britannia double oven, gas hob, electric ovens. Can’t find the model number sorry.
Anyway it does not heat up if I turn it to normal oven, either top or bottom or both. Grill is fine. But if I use the fast preheat option it gets to temperature quickly, so elements must be working. But if I then turn it to the setting I want then it just cools down. Have tried various combinations but always the same result. Grill fine, smaller oven fine. Fan working as expected. Would be grateful of any advice, thank you.
