I have a fan oven at home that's only a few years old. About six months ago it started intermittently emitting a horrific sound, that I was able to trace to the fan at the back of the oven scraping against the heating element that surrounds it.
Closer inspection suggested that the heating element had warped, so I bought a replacement online and fitted it.
So far so good, until a few weeks ago when the same sound started. Same problem, but this time I'm just not able to get the heating element into a sensible position.
The photo below shows (with a panel removed) where the heating element is scraping against the fan (Note that this photo was taken after I had fitted the new element, and all was well).
The small screw in the bottom-right corner allows for (limited) adjustment of the shape of the heating element.
And there are three clips that hold the two windings of the heating element in position with respect to one another (one of which also has the adjustment screw mentioned above attached).
The heating element is attached to the back of the oven by the flat silver plate in the top-left corner, and there's no scope for adjustment there.
Can anyone suggest what is going on here? How roughly can I attempt to manoeuvre the element into position before I damage it?
