As far as the make think its a howdens own make HJA 3650 the oven heats up fine on boost but when you turn the knob to the bottom oven or even on to the bottom an top oven it stops heating up think the bottom element has blown but am unsure

Howdens do not make it, some manufactures rebadge, they use hoover for washers. But, you need a test meter to find out problem, might be bottom heater, but, I would tend to go for control switch 1st. Again, you need a meter to find out, just check every thing. With it disconnected.
