I have a new-ish (18 months or so) built in double oven. When I use the timer function there is a fan that comes on and stays on until the oven comes on as planned later. My previous (also Siemens) oven didn't do this - with that one you set the timer and it all went quiet until the oven came on. I find it really annoying and wonder if they all do this or is mine faulty. Can anyone advise?
Thank you!
