Oven repair needed

[rainbowtrolley]

Hey! I have an electric oven and the fan is making an awful racket. Still seemed to be heating up, the time I tried using it, but I don't want to risk anything else with it. Is there anyone local (I'm in SE15) you could recommend? Thanks!

Is it the fan inside the oven that’s making the noise or the fan that extracts? If the outside one make sure there isn’t a pea / bit of pasta etc in there. Just look and if you can see something get it out if you can. With checking the inside one for debris and obstructions too - when the oven is completely cool, obviously.
