Hmm yes perhaps, I tend to think of a dial as part of a measurement device. So a volt/ammeter has a dial, a clock has a dial etc. I suppose I could see myself calling the temperature setting of a cooker the "Temperature dial", but not the mode selector knob thing. Mode/Temperature selector is quite a good one actually. Still doesn't come to hand like knob does though.
