I’d really like to thank you for this thread! we have the same oven and the top oven stopped working yesterday – no light no fan no nothing, the bottom oven was working ok. I went on to Google this morning, found your link quite easily and joined the site – followed with interest this thread – my husband opened up the switch panel, saw a similar problem in that a spring had come out of the switch controller – took it all off and managed to reposition the spring( took while) – put it all back together & ‘Hey Presto’ all working again! Bacon under the grill right now!!
Thank you so much!!
