Hi.
I’ve noticed over the last week that a problem has developed with my oven (Brand = Neb b&q own brand).
Its a fan oven so usually i dont have to preheat it before i cook something. However, these last few days, its taking about half an hour to get to the required temperature. Eg. Last night i cooked potato wedges, i preheated the oven for 10 mins then cooked them for 30 minutes. After this time they should have been done but they were still rock hard. It took another 30-35 minutes until they were cooked.
Any ideas why this is happening?
