Hi, firstly, thanks for a very informative and useful site.
Secondly, my cooker stopped working 2 days before Xmas (Of course!)and, as the selector switch had been clunking round for some time i assumed it had failed. There was still power to the cooker, the gas hob and clock were still working but that was it.
I ordered a new switch which i only fitted yesterday due to various circumstances, but it didn’t make any difference.
Then, this morning, i was reading a post on here from someone else whose cooker had failed in a similar sounding manner and they mentioned that the element was perished.
I checked mine and the bar that supports the lower element had come away from the slot it sits in on one side, dropping the element by about 5-10mm.
I replaced it and, hey presto, the oven started working again!
Hopefully someone else in the same situation may find the above useful.
