Keep the sequence
Describe the selector position, display and fan response. Say whether the knob physically feels different or simply produces a different cooking result.
Why inspection matters
Control and heating faults cannot be separated reliably from a front-panel photograph alone. An assessment can consider the selected path and actual model before recommending suitable parts.
A useful distinction
If two settings that previously behaved differently now appear identical, describe them by their symbols. That comparison may help assessment, but should come from ordinary use already observed rather than extra trial cooking.
