beko d532w?

I have a beko d532w electric cooker, my oven and back right hob stopped working, as suggested I took the thermal fuse out and tryed thrown it off the floor, this didn't sort my problem, I then bought and replaced the bi-metal thermal cut-out & cables with no luck, I thought it could then be top oven door switch as the oven attaches here and had no joy etheir. I'm left scratching my head on this as the top grill wire with the bottom oven wire does get the oven working, I'm really confused on why my fixes haven't got it back to perfect working order and wonder wither anyone is able to help me on what else it could be could it be thanks
