After using the microwave function often today it suddenly decided to arc or if I have got the word wrong, sparks shooting out from, what appears to be the attachment of the quarter circle shaped fan or similar in the centre of the ceiling of the device. What do you think can we do about it if anything? Thanks.

So has ours, so I did a search, and evidently there is food matter in the channel that leads the microwave radiation from the magnetron to the oven cavity. I'm going to take it to bits tonight, and clean it.
